[@ButlerRudd]

Can I ask a question. For the 4 months did you literally do zero work above MAF HR?

[@thatguygreg]

Good video. I´ve been running at MAF almost exclusively for 18 months now. The first three weeks of MAF training was the worst time I´ve ever had while running. Wose than being injured. My ego took a real beating. So frustrating! I was close to tears at one point and I nearly smashed my running watch out of sheer frustration. I had to slow down from around 5:20 / km to 7 min / km. Everyone was passing me and my HR alarm was constantly going off. It seemed like I couldn't run for 30 seconds without having to stop and walk to bring the HR down. But it got better. Improvements came slowly but steadily. I'm now running between 5:20 - 4:55 / km at my MAF HR, depending on the day. Before MAF I was running about 35 - 40km a week and every time I tried to up my volume I would get hit with runner's knee. Now I consistently run 80 - 100km a week and runner's knee is a thing of the past. The MAF method isn't exclusively running slowly and this is a misconception many people seem to have. There is a time and place for speedwork or rather efforts at higher HR. Those who have never built their aerobic engine before (like me) can make incredible progress just with running in the MAF range for a long period of time. In the 18 months I've been running at MAF I've only done about 8 higher intensity workouts. I did this mostly to add some variety to my training and to see how I was progressing but I stayed strictly within my MAF range for a full 11 months before trying anything 'harder'. My higher intensity efforts were all guided by HR, eg: I'd add 30 mins at zone 3 / tempo to a normal 80 minute run, so 30 min WU in MAF range, 30 mins tempo, then 20 min easy with a walk home once I finish. Strides are excellent and a perfect complement for MAF training imo. I do between 6 - 10 strides after a run 2 or 3 times a week. I really agree with the changes or tweaks you're making to your MAF training. Some people change it too much and insist on still doing some speedwork when they just start out at MAF which is wrong imo. What you're doing is still pure MAF. The strides won't elevate the HR above aerobic zone for a long enough time to have a negative affect on your training and I think there is minimal injury risk with this.

[@garylq]

Good plan. I did 7 months of pure MAF in 2019 using the 180 formula. During that time I improved by about a minute per mile at my MAF HR, but when I started to re-introduce intervals I realised I'd completely lost all my ability at higher intensities. I abandoned MAF after struggling around the 2019 Berlin Marathon in 3:59. Since returning to more traditional methods (all my easy runs and some workouts are now done by feel, blind to the watch) I've improved to 3:19 (Goodwood Marathon 2020, 54yo). However, I don't regret trying MAF. It gave me a good base and I learned several valuable lessons during the experiment.

@@david7101 That is where I am thinking, this guy just described dropping his old routine, which made faster, to strictly do a single method.

[@Dirtydreamer2023]

[@tackjibe]

7 months is not enough time to give MAF a fair chance. That is the point at which you can introduce once a week interval training while maintaining your MAF heartrate on all of your other runs. With once a week interval training, your natural stride will return after awhile. You can start racing 10 k races, which will also improve your stride. 3:19 is an impressive marathon time at age 54. With consistent MAF training you could go under 3:10. When I look back I wish I had started MAF training from the beginning. I'll never know what my PB (3:16 age 55) could have been.

[@posner2]

100% agree with what you said. Best MAF advice I’ve heard. I made huge improvements once I added strides to my easy MAF runs

[@tackjibe]

I started MAF training 3.5 years ago. At that time I ran a half marathon at 1:42 at age 66. Three years later, at age 69 I ran the half marathon in 1:38. MAF works. I no longer stress about tempo runs and long runs at a certain pace. I go by heart rate. When it is hot and humid, I have to slow down, when it is cool and dry, I can go faster. All at the same heart rate. It is amazing. Once a week I do about half an hour of interval training, alternating weeks between hills and flat ground.

[@FreshTopEnd]

[@craig2679]

The main benefit of low heart rate training is staying injury free. Training to HR means if you are feeling terrible one day your hr dictates the pace so you're not overdoing it trying to chase a specific pace. So my slow runs based on HR range from around 4:40 per km to 5:30 based on how my body is feeling on that particular day.

[@beerandchips2545]

That's exactly right. I've been following the method for about 9 years, with a lot of success in racing and training, but when my mental health took a nosedive, it really reflected in my heart rate.

[@nickhyland9497]

I started doing something similar based on a program my smart watch gave me. I was using below 70% of my max heart rate at roughly 140. I found out painfully slow and difficult to hold, was often changing to brisk walk. However I then went for a VO2 max test and as part of it my aerobic and anaerobic thresholds were defined. I was given an aerobic threshold of 151 and advised I should be doing my slow runs below that. Using this as my threshold made things a lot better to manage and it does still feel easy. Been running at that for a while now and definitely seeing my pace improve at that pace

[@davidporter2828]

Good, I'm glad to hear someone talk about the need for "some" faster (for you!) running, in addition to the easy relaxed low HR work.

[@robertcook6476]

Why not just do 80/20 as per Matt Fitzgerald? Same principle large volume of easy running with smaller volume of harder running. The key is understanding what easy running actually means for your current fitness level, time of day, temperature and humidity etc. I find a simple well of checking if your easy runs are at the right level is to see if you can breathe in and out through your nose all the time, you get very instantaneous feedback if not, the advantages of this (as I see it) are you don’t need to use any HR data which relies on actually knowing a number of parameters, such as your max HR for running, assumes your device measures your HR accurately etc.

[@pam00088]

The theory goes that, at least to begin with, the 20% of higher intensity still gives plenty of scope for overworking the system. Maffetone allows for moving onto 80/20 once aerobic base improvements have plateaued. Also, unless I have misunderstood, Maffetone is all about learning how to pace slower runs with the aim of ditching reliance on HR as a measure of what is appropriate. MAF HR is just a starting point for this along with being a useful bnchmark for use in periodic MAF tests.

[@packfodder923]

Matt Fitzgerald 80/20 is a misinterpretation of the research.

[@kites4121]

[@dirtridergrandpa5873]

At 61 I Started MAF appx. 9 months ago. I've experienced great results. My speed has increased, I get more miles in each week and actually enjoy running now. Before MAF I had to force myself to run because of the stress on my body. I can now run multiple days in a row if I want due to shorter recovery time and no injuries. After 6 months of just MAF I have added some speed and hill intervals. Another benefit of MAF is a focus on good nutrition. So with better nutrition and more running I have also lost weight!

[@Bradl0y]

What i found with maf in the last year is how to run easy. Maf in the last year has gone for 7min/km down to 5:35/km at 128HR. I now started this year to do more 80/20. But i know how to run easy now most of my runs avg 125 HR at just under 6min/km which I'm happy with.

[@exerciserelax8719]

I agree with this. I'm not an exercise scientist but have read some very convincing takedowns of MAF by people who are, however, almost all of them agree that easy running should be the bulk of your training time, especially in the early part of a training cycle. The best runners in the world mostly train that way (there are a few exceptions, like everything else, nothing is universal). Many of us never learn easy running because we start off at a fairly low level of fitness and always associate running with working hard. Many of us are also out of touch with our bodies and can't really tell how hard we're working or when our breathing rate is increasing. It can help a lot to have an objective measure (HR) to use as a tool to keep you at an easy pace and give you feedback about how that feels.

[@clairesweter-millar260]

If you have patience it works. I do majority of my runs around 132-135 bpm. I’ve noticed my paces are increasing on my faster efforts. I also work on my form during my slower runs.

Awesome Claire!

[@davidherzog4379]

I have done MAF/low heart rate training in the past and did see progress at the same heart rate over time. I went from 11:30 min/mile to 9:00 min/mile over about 6 months training. I did find it helpful to teach my body what "easy" running means, but I eventually stopped the method and mixed in speed work. In other words, now that I know what easy running means, I don't carry my heart rate monitor with me anymore and I run for feel on easy days. On fast days, I run fast. My body has responded well to this (better abs/muscles) whereas during MAF training I felt like I developed a gut. I think this goes hand in hand with what you said in this video.

[@ethers]

You are absolutely correct about the leg speed issue with low heart rate training. I did MAF for 2.5 months and my MAF pace plateaued and would not budge for weeks. Out of frustration I did some faster running and my MAF pace *immediately* started dropping and over a few weeks came down by 35 seconds per mile. This is clearly a neuromuscular issue, and while I will always emphasize low heart rate training. I will also make it a point to add in bits of speed for muscle recruitment, etc. Something as little as strides a couple of times a week is enough when not training for races. You have to keep the body guessing! Interested to follow your journey to sub-3!

[@samueljele]

That is actually part of the MAF method. When your MAF pace starts to plateau, you add in some hard workouts; but only after you established a good aerobic base.

Slow jogging has vastly improved my endurance and my speed has increased as well. The method is excellent but those calculations are nuts.

I've only been running for 2 years, and really started running more in March of last year. Last November I bought a heart rate chest strap and went full zone 2 running (using HRR zones), around my maf number, it was very difficult at first. I actually got even slower for a couple of weeks. But after 4 months or so it's been amazing, i'm still running slower than i used to but my heart rate is staying in the 130's and my pace is improving slowly by the month. I've run half marathon distance 3 times this year, my longest runs, and 2 weeks ago was first time I did HM distance in zone 2. My legs don't ache every morning now and i'm working on upping my weekly distance (doing around 50-60km currently). I think the moment I realised it was really working was when I was running along in Feb or March, and my mind had wandered for a moment and I realised that I was completely comfortable running, no heavy breathing or feeling tired, just could keep going until I got bored(or my legs give up). Can't recommend it enough.

Your blood volume's divided between tasks when it's really hot and your heart's given an extra job to do: pumping blood to the working muscles, yes, but also pumping blood to the skin to cool you down. Therefore, for any given heart rate, you'll have to back off the pace a little. One way to get round this is to think about layering DOWN (dress code). Another's to consider the time of day you run at. Not always a practical consideration and of course, depends entirely on your working day and home life but if you can get out really early in the mornings during the summer months you avoid the heat of the day. It really does help you direct most of your body's resources to the working muscles rather than any extraneous factors.

MAF training isn’t just slow, HR Zone 1-2, running. After 3 months of anaerobic base building then you slowly start to put in the training runs: hills, fartlek, intervals, tempo, threshold. During the early 3 months you can still work on form, cadence (I went from 163 to 170), breathing, and endurance so the time is well spent. True run training is a long-term goal, not a sprint to one race. I started MAF training this past August running about 10:15/mile pace but now am under 9:15/mile most days, even had a couple at 9/mile. Started a 12-week Strava marathon training program in January and just ran 3hr 2min at age 40. Speeds your recovery, helps prevent injuries, gets results. Highly recommended.

I've done MAF for over 2 years but I was already running really slow on my easy days so for me it was not a big adjustment. I have improved a bit but not that much. I have improved a lot since I started incorporating workouts and working with a coach that uses power as the main guide for my training. HR can be affected by so many things that I find it quite unreliable. If your HR strap is not wet enough, if your HR strap has other technical issues, if you drink a lot of coffee, if the weather is really humid, the lag in feedback to the watch, etc, etc. I find that power is a much more powerful tool and reliable as well. I have been running for 15 years and my fitness level has never been this high.

Your comment is three years ago but nevertheless I got curious about "power". What did you mean by that?

James, the way you are modifying the MAF training, sounds a lot like 80/20 training method which has been been the foundation of probably all endurance runners for decades, except that it didn't have a name. A focus on purely MAF without any neuromuscular stimulus, would simply result in a slow long distance runner. Some speed work is essential, and this is where the 80/20 rule comes in or your modified MAF training. I look forward seeing how you go with it. I'm following a similar plan but I don't focus on HR. I go by feel. I'm going slow enough when I can have a chat with some imaginary running companion. Then add strides, sprints, hills etc periodically.

I will add this very good article, see link below, based on a lot of research done by Stephen Seiler (he's also on youtube) about the question of how much should you train. For endurance athletes the data is clear: lots of low intensity work but interspersed with high intensity work at lower volumes: www.8020endurance.com/seilers-hierarchy-of-endurance-training-needs/

[@jf8138]

I have been loving MAF training. I have been an athlete since I was a kid and always ran a 530 mile, wrestled for 10 years, did taekwondo for 10 years... The low intensity and easy healing of MAF training is great, and I have never come across a sport where you get a chance to stick in that zone, for so long, so it is new for me to do this level of low heart rate training. I wish I had started sooner in my life

[@peterkisidaj9329]

Hi James, thank you so much for a great topic!!! I'm learning to run slow but t's even harder that run faster :) at least for me. I'm almost struggling with it, because I need to almost walk to get below 135. But this is what I really want to achieve, easy/aerobic base runs mostly with low HR and I've just started to add some strides at the end, just 400-500m up to 1K.

[@d-tect1621]

Just strated MAF training week ago.. my MAF HR 153 but I keep it below 150. It's so frustating.. I used to run 5:30 - 6:00 pace/km now I have to deal with 8:30 - 9:30 even 10:00 pace/km.

[@jamiemegson5291]

I’m not doing exclusive MAF training (I’m prepping for a 10km race in May so balancing low intensity with some tempo/speed and goal pace sessions) but I am keeping some of my easy/long runs around my MAF HR (144bpm). I’m also doing a MAF 8km test each month, which is really helping me to see my fitness improve. I’m logging the splits as well, but headline figures: first MAF test, average pace of 7.46/km. 2nd test- 7.14/km. So definitely getting faster at same HR, fitness improving!

[@kleitosaliagas5668]

How many months did it take you to go from 7.46 to 7.14?

[@lizaho246]

I started maf as I was actually over training and got an over use injury... I was running my easy runs at around 8.30 pace felt easy but my hr would always be around 160 odd... So I did 145 hr for 5 full weeks Inc on my bike and actually built up miles while managing an injury.. Now its sorted I am doing 1 rep session per week a tempo or hill.. At harder efforts.. Anything else is all now under 150 hr... I ran 18 miles on Sunday my hr didn't go over 145 an my pace was 9.45 average when originally I was at 11mm an needing to walk on some climbs... I think its brilliant for easy days.. But yes you defo needed to run fast efforts of your looking to race as I noticed my first tempo run I got sore quads because they hadnt done pace for so long... All in all for me it's working for me with the added efforts as and when

[@wunderlichdrive]

Sounds very similar to my current training block, which I am wrapping up (I am tapering now). I have a goal of sub-3 marathon, but because I am 55 I knew that I need to slowly build up to that. So, my PT gave me the advice to scale first my volume, then frequency and lastly intensity. I had been training at a max of 85 km/week for a long time. Then about a year ago, I bumped that up to 110 km/week. I did one block at that volume, then between blocks, I maintained that volume, but focused on keeping my heart-rate at/under 120. That slowed me down a bit, but I was able to maintain the volume without feeling muscle fatigue. I would add in 1-2 sessions of 6-10 strides per week. Now, in this block, I feel really close to my goal. Keeping up the volume inbetween blocks really helped me build up good endurance and allowed me to add in the more intense sessions, following Pete Pfitzinger's book. In 2 weeks, I will try a solo marathon run and I think I should be able to hit 3:05 - 3:10.

[@And-rc9yy]

Sub 3 at 55 seems really impressive. I write 'seems' because I'm only a year in as a runner. I'm registered for my first official marathon in November. I will have turned 50 two weeks prior to the marathon. My PT suggests I can go 2.45, I ran a 3.03.08 on my own during training but taking a further 25 seconds per km off would be tough. My PT has me working on speed work at the moment but I feel I'm constantly on the verge of injury. The PT tells me I'll get to do some longer slower miles in the coming months, quite frankly I'm eager for that. I enjoy the speed work, but I feel I'll benefit the most if I can get my body used to running 20+ miles. Good luck for your sub 3.

[@kozepz]

I started with MAF to tackle the aerobic deficiency syndrome (ads) as it's a good baseline to start with. Now my calculated HR zones are based on AeT and AnT. I really do enjoy those low intensity runs.

[@magdalenawalton1215]

I started yesterday. My MAF hr is 140. It went pretty well my pace had to be around 11;00/mile. Hills are the challenge though, I had to walk the steepest ones.

MAF + Chi Running are very complementary. Maf for the aerobic training and Chi running for the the technique and neuro muscular part (chi running is based on taiji quan after all)

[@tbgoog]

At 54/100kg I am spending a couple weeks in MAF hell now... Garmin watch tells me to perform running workouts at 10min/km! So I prefer to do these "runs" at night while _hopefully_ improving ...with some initial privacy. After times of much-too-high-HR training and then close to nothing in 2022, this is the only chance. Great to read of these great advances achieved with MAF!!

[@enriquesundiang3558]

I just started last month on my structured running when the pandemic subside, we have the similar method. I'm currently at my base phase MAF. Doing strides intervals right after the long steady easy MAF session.

[@Julian-pj2zi]

Very good advice James.. I did a full year of low HR training (it did work wonders for my aerobic base) but then after that when I introduced a hard tempo run once a week I soon got a case of plantar fasciitis. Just recovered from that and I think I'll follow your tip to build a few pick ups and strides in before starting the high intensity work again. Re: MAF formula, its pretty good for approximating your starting aerobic threshold HR but it doesn't take into account that this level drifts upwards over the months with aerobic training. I started at 138bpm but after a year of low HR training my AeT was 150+ bpm. That said I mostly shoot for low 140s so I can easily keep the volume up without risking injuries

[@GruntProof]

Good stuff

[@theparalexview785]

I tried the slow, steady approach beginning a few months ago, and gradually improved my pace... for slow, steady jogging. It didn't help at all for strides and sprints or faster steady running. Every time I push the pace I find new body parts getting sore and risking injury. It's an okay approach to base fitness, but the only way to get faster is to run fast, which means longer strides, faster turnover, and risking injuries to rarely used muscles for those of us who haven't built up a base from years of running. My base aerobic fitness was already really good from years of cycling, but the leg and body ergonomics are totally different.

[@AnTalk_blog]

I tried the MAF method last year. Probably I should have used the 180-50+10 formula. My starting pace was ~6:20/km over 10km distance. After 4 months it went down to ~7:00/km, I was getting slower. Very frustrating experience. I did increase my monthly distance to 200km/month and lost some weight (was not overweight to start with). I learnt to pace my runs better and watch my HR. Currently following a Garmin training program with Coach Greg. It's more like 80/20 with higher pace based easy runs.

[@anitahendrix7573]

Have run some 5k in my past and now am very inactive. Won a few firsts because I out lived my competition. Now at 80yo and having gotten threw some back and Hip problems want to get back at it again.Did the calculations and my maxHr is 144 so think my 70 percent is 102 that is just walking for me so far am doing 20min every other day and will see how it goes. Doing strength training twice a week so far Any tips at my age???

[@garrettmoriguchi9253]

As another viewer pointed out, the MAF method does teach you how to run at slower paces without taking awkward strides. However as James pointed out, after two months of MAF running, it felt really awkward to run at tempo/threshold. My stride felt really disjointed and my heart rate was higher than usual for the given pace. It should be noted I didn't follow MAF strictly; while I'd do 30-40 miles per week of MAF running, I did include a single 1.5 hour threshold cycling session as my "fun" cardio (and yes I realize that's against MAF training). While I was making progress with my pace on MAF runs shaving 30 seconds/mile off my time at lower heart rates than when I began MAF training, my cycling during that time suffered with higher heart rates for the given power output. I really don't understand how other people can do MAF only and then smash records when they go and run an organized race.

[@AlexVoinotGuitar]

Some great pointers in that video. I've never followed MAF training, but I have a similar approach to my running (my max HR reaches 200 bpm at the end of a 5k race, when sprinting to the finish line and giving all I've got), and I do most of my base endurance training at around 145 bpm. HR is a great effort indicator, and it helps me stay in the proper zone during extreme weather conditions (wind, heat, humidity). I also agree, training there all the time won't make you faster, if you want to do so, you need some faster running in there as well (tempos, strides, intervals). If fast running were a house, the base endurance pace is the foundation and exterior walls, threshold training is the framing and roof, and speed is your shingles and chimney.

[@DB-kq8kp]

What a great post and video. Just started this as training for an Ultra in 12 months. 7.25/km at 130 bpm baseline as a start but I'm in Middle East running in 35+ Deg C heat. So think the HR would be a bit lower / or I would be quicker etc in sunny Scotland.

[@trummscott]

My issue with using this training is my heart rate is higher than it should be since I have asthma. I’ve tried multiple times to get it lower all the ways I’ve heard to do. So I use perceived effort for runs.

I did 10 weeks of MAF only running at the end of last year. I was frustrated and bored, and I didn’t see much progress in that period. I still partly run at MAF HR, but now incorporate intervals, tempo, and hill work. At 45 years of age, I am now running better than I ever have. Don’t know if that is down to the 10 weeks of MAF, but I think I’ll do it again during the winter months.

[@Spartan117FS]

10 weeks is too little time for the MAF method, you need to commit for 6+ months.

Followed MAF for Ironman training for years then moved more over to Mark Allen who slightly altered it which works better. If anyone who knows who Mark Allen is, you can say it works. My HR now sits at 4min ks at 140hr.

[@prashantfadnavis852]

I have done Maf training for one year before shifting to Zone 2 training . My advice to you would be to get a chest strap heart rate monitor for yourself for accurate heart rate data if you don't have one. Wrist based optical heart rate monitors are woefully inaccurate.

[@DonGivani]

True

[@pauldonlan6408]

Good video, some healthy scepticism here in the comments, but I’m on board with this idea of long slow running for base training and developing a healthy body with low stress levels. Maffetone himself puts emphasis on the holistic approach to health, as James Dunne does, with performance improvement a side effect. I’ve been running in this same manner for the last 2 years, and at 51 I’m as strong and injury free as I’ve ever been. Perhaps my performance would be better with more hard intervals, but I place a HIGH premium on staying injury free. I do some strides and short repeats, I find hill sprints are a great way to get some of those benefits with lower injury risk.

Started LHR training about 3 month ago, and I can finally run for longer distances without feeling worn down.

Okay, now I feel better about being at what I consider a much slower pace lately. I've been noticing that a lot now that it is warm enough where I live to go back to running in the early am. There are a lot of factors that my body has not been exposed to for a while, like extra humidity and the pollens in the air from everything putting out buds or actually blooming. Also, I am over 50 and I need to remember to give myself credit for doing this at my age. It will begin to pay off in a few more months; I will get faster and more efficient with time.

I have a strange experience. I've been running 80/20 for 2 years. I decided to do MAF-pure. I've been running MAF 8km for 45 days. Every other day run (then rest). Chest monitor and tracked routes. Exactly 137 bpm (180-age) for the whole run. My times over 11km (GAP analysis adjusted) have INCREASED my times by km. KM1 +1:01, KM2 +1:23, KM3 +1:24, KM4 +1:19, KM5 +1:30, KM6 +1:38, KM7 +1:28, KM8 +1:54, KM9 +1:38, KM10 +1:45, KM11 +2:16!?!. I don't do any anaerobic exercise (as per Lord May) - only strength training. I'm fit and not overweight. I hydrate. I had no changes in eating, and stress was the same. I have only got worse!!! My average first MAF per km run (11km) was 5:49 min/km (SD .01) and now my average per km MAF run is 7:24 min/km (SD .02) (over 11km). So far... this has just been a terrible experience.

[@infl8urshoes]

I have had a significant problem with adhering to the MAF training method. The "180 equation" sets my rate at 113, while lab testing last fall identified my aerobic threshold at 104, both quite low numbers. My max HR north of 180 is reportedly atypical for someone my age with a history of a sedentary lifestyle [and humorously enough, as I sit here writing this, my watch alarm just went off warning of an excessively low heart rate of 45 - LOL]. The problem I continue to have with MAF base training is that it has become ridiculously difficult to walk fast enough to hold a pulse near 110, and any amount of Kenyan shuffling or similar spikes my pulse to 140 or above almost immediately. Holding 110 (as measured by chest strap) involves mere moments of jog/shuffling with slightly longer moments of walking, repeated over the two-hour period I've decided is desirable. I'm not claiming MAF training doesn't work, because I have been able to increase the time and distance I can actually run, but I am observing that for some people's physiology it is very challenging to implement.

[@2spoons]

Hi James..... I'm only a few years older than you lol and have been Maf training for about a month now... (the difficult stage)... my HR is 135 (180 - age +5 for fitness) - don't forget you don't need to carb load anymore... (try and cut out the pasta, white bread, jacket potatoes) and let you body get used to eating the access fat in your body as energy ... painfully slow as I was so used to running 7:50 pace until I started Ultra running - I can't wait to see if my pace starts to increase.... patience I have little of... uh oh

[@ScottMoyse]

I used the MAF method heavily when I started running 2.5 years ago... I feel lucky that I found it so early on! I definitely experienced the speed increase over time.. but that improvement is limited in my experience. Probably for some of the reasons you mentioned. I'm no running about 10bpm above my MAF HR for my aerobic runs to see how that goes. I want 4m30s k's to feel like my easy conversational pace... whereas 5 is where that is currently. I do like your logic with regard to reminding those legs what running fast feels like though!

[@cianmulligan5696]

I started a weightloss program this week based on the MAF method. It's Dan John's Easy Strength for Fat Loss. The basic program is, 5 days a week you do a moderate intensity kettlebell/weights workout for 10-15 minutes to get the heart rate up, then immediately go for a walk/run/cycle for 35-45 minutes, carefully staying within the MAF zone. For me, as it is early days, I am constantly checking my HR monitor to make sure I am on target. I have already realised walking just doesn't work for me, I can barely make the minimum MAF band. I'll be alternating running and cycling from now on. Hopefully I will become aware of how much effort I'm using soon so I can relax and stop obsessing about my HR rate!

[@cassiel6217]

I just started MAF training and managed to hit my PB distance without feeling too tired or getting pains afterwards. I used to do a lot of tempo runs (previously I did 4'50'' for 8k) but I'd sometimes get joint pains after I finish the longer distances with such a speed. I'm still battling with slowing down (I'm kind of competitive so it hurts to slow down so much) but it also impresses me how I can run longer distances without injury and fatigue now

[@bmp713]

I think the ideal training intensity is the range MAF - Max Steady State, or the hardest intensity you can maintain without slowing down for at least an hour. 130-150HR, Zone 3 for most people, recommended by most professional runners and coaches known as Cardiac Output.

[@marcvanderlinden7618]

Great video as ever. I also started putting in low HR sessions and, clearly, this implies a drop of c. 1min per km from the usual medium pace; feels a bit boring at the beginning, but one gets used to it relatively easy. The most difficult for me is to keep a high-ish cadence without speeding: otherwise, I know I tend to slow down and to pound down on the ground

[@davidporter2828]

I agree, if I go really slow i feel like I sink into the ground and feel the ground impact forces way more; and simply end up training poor form. This can be a disadvantage of sticking 100% to MAF.

[@daveleitz9107]

I've got Maffetone's book. It's 516 pages. To focus entirely on the simple 180-[your age here] formula is to miss out on a huge amount of other information relating to the method. And one can certainly supplement knowledge with information from other sources, for example, like KZbin. I've learned a lot about foot anatomy and optimal foot strike by watching videos examining the running form of elite athletes. I was doing it wrong, and it's something you really can't learn from a book. Before saying Maffetone "doesn't work," one must ask oneself, "did I really follow the principles of the method or did I take a formula and tack it onto what I was already doing?"

I am using heart rate training since quite a while and I am mostly happy with it. (I am not a good runner (too heavy) I just do it to maintain endurance for sports I enjoy but cant do all the time) ... In any case I have the problem that when I occasionally go faster to see what pace I can sustain, I am not limited by my cardio but by my lower legs - they just get weak before I get out of breath - sometimes I even get needles and pins. It feels as if they just cannot handle the amount of energy they are supposed to process. So now I "run" a bit up the hills to develop strength in my lower legs, however its almost walking alternated with actual walking, when I want to keep my heart rate. I may switch to ignoring heart rate for hill runs once a week or so ... not sure.
