As a older beginning runner 35 and formerly morbidly obese zone 2 training has been absolutely working. After training for about a year I bonked at around 19.5 miles in my first marathon and finished at around 4.5 hours. At the time my average heart rate was about 167 bpm. I immediately started zone 2 training and after about four months keeping my easy pace around 148 bpm, I can now run at my former marathon pace without going above 155 bpm. I gave myself the challenge of running 10 miles everyday for 30 days, currently on day 26. I don’t think I would have been able to attain this level of fitness without focusing on slowing down. I may extend this challenge significantly to 100 days, but that’s not a promise yet…..and yes most days are now fasted runs.

[@forrestgumpny6930]

Aye man let’s go . 37 former really big boy too . I’m all about the hr training peaked a few years ago at bq ready before I got struck with Covid * too many times . Back at it now . Good luck with zone training essentially never too slow 🎉

[@Cloud007.]

good going! I would just suggest to recover well and make sure you're not running through injury! Also, maybe mix it up a bit with the types of training you're doing? But completely up to you. Either way sounds like you're an absolute animal at this and big respect for getting strong and healthy!

[@smothyism]

That's excellent overall milage per week there is no dought that will make you a better runner Add strides to the end of each run this will make you fast with low injury risk. Do 0.06 of a mile recover 0.06 of a mile between each stride do 3 to 8 at end of each run. This will give you Massive gains.

Z2 has been game changing for me. I used to think no pain no gain, but that's BS, it just led to injury after injury and doctors telling me to stop running! So I did. This year I turned 60, and I decided I wanted to be fit and healthy again. After much research I started running, slowly, using Z2 as the barometer. I log my results each month and my pace has improved by nearly 3mins/km in 8 months, and importantly, I'm not getting injured. I wondered if I could still run fast, so did a 5k, and hit 21m16s, much faster than I expected, without any speed training. Not only can I run again, but I'm fitter than ever and entering my first 50k trail race next month. The most important thing, I love running again.

[@Steveness100]

That’s awesome! I’m 54 and just getting back to running and managed 22for 5km but I need to slow down as I’m copping too many injuries. You’ve inspired me! 👍

This is fantastic!

[@st4331]

@@Steveness100 That's great, you'll probably break 20mins soon! One of the major benefits of Z2 running is building an aerobic base. When I ran the 21-16 5k I wasn't tiring; I might have been able to keep going for another 5K, whereas when I ran 23-20 a few years ago I was tiring badly towards the end.

[@PoetWithPace]

Well done buddy and great to love running! At what point did you find out that no pain no gain was BS?

[@st4331]

@@PoetWithPace I used to run hard all the time but was constantly getting injured. In my 40s I developed sciatica and after MRI scans doctors advised me to never run again or I might end up in a wheelchair. A couple of years ago I started to watch videos on running form and learning about HR zones. With this knowledge, and focusing on 80:20 with most running in Z2, I am now fitter than I have ever been, even than when I was a county runner at school. I can't run at the speed I used to , but have developed the endurance to do a 50K Ultra in 3 weeks, after which I will focus on speed work as well and hope to break 20mins for 5K, and 1hr 45mins for a half marathon, which I think would be Ok at 60. So a lot of gain comes with no pain, just enjoyment, though for my next goals I will have to extend myself.

[@robogarden5723]

You seem in better spirits in the video. I hope so. You da bomb my friend and inspire many people on here with your threshold runs. I am not sure what to make of Zone 2 yet, it just feels like a cycling term to me and zones in general. But thanks for the explanation!

[@adamfergie87]

I've never been so sure about zone 2 hype. I've always run at threshold or above regardless of distance and have been in and out of injuries regularly. This year I changed to 1 short fast run zone 4+, one threshold zone 3 middle distance and the long run zone 2. This is my first injury free year in 10 years and I believe it's down to this and strength specific training.

[@em34ev3r]

[@alane3983]

You look really good running. Your form is enviable. You are more than twice my speed and that’s when I’m fresh. I have been base building all year and will continue for another year before I even think about my goal to run a marathon. But I am 62 and only started running a couple of years ago. But I do a lot of climbing hills. As part of my training, I am working toward 120,000 m elevation gain this year with most of it in zone 2. Next year it’ll be 150,000m. But I have to add back in some flat running. Man, I went for a flat run for the first time in many months and I can’t believe how sore I was after and how quickly I fatigued. Use it or lose it. New goal will be 50km/week plus the elevation. That should help. Nice channel. I do like the zone two training but definitely have to add in the higher intensity stuff regularly.

i have been doing quite a bit of zone 2 running since my last marathon built-up last year. i didn't get the importance of zone 2 till i see my marathon effort training has become easier, and more importantly i could clear up my lactate for a more intense session the next day. that said, i seldom do morning run without any food. it might not be as efficient as fast running, but for me i can easily sustain a 40-50min zone 2. that's very important.

[@ddhurry4168]

What I love about z2 running is that because you're not stressing working too hard, you have the mental space to think about the run dynamics/efficiency and work on that. If I'm trying to stay z2 on a 2 or 3k hill you see that HR going up and experiment upping the cadence, adding a tiny lean, focus on the knee lift or on the stride recovery and seeing if you can run easy more efficiently. Bottom line the available mental space of easy runs can be used to work on efficient running

[@jenHry-ng3pw]

I believe that the improved running efficiency is part of the benefits that come from the increased volume you can recover running in Z2. Second is strengthening the body with lower impact volume, so you don't get injured, leading to even more volume over a year. Third - the pain free workouts enable you to look forward to your next training session, again leading to more volume.

[@timtrenholm3698]

Getting a test done if only to see the LT1 and LT2 HR areas is all most of us need. Which gives you 3 HR zones. Sub LT1, LT1 to LT2, and above LT2. Spending over a year with 80% of my running below LT1 has had massive improvements to my overall running ability, days per week I can run and consistent mileage I can hit. Easy pace has dropped over 1min per KM in just over a year. As someone who used to run 4-5days a week, with WAY too much intensity and starting to break down too often, all the easy running has now got me to the point I run 7days a week averaging 100km+ a week in my 50's. Once you commit to easy running and are willing to put the time in to allow all the adaptations it provides....the results are CRAZY. Keep fighting the good fight Stephen, and keep giving us your unique personal perspective!

zone 2 plus strides is the qpproach I am now stickinng with as a non compettive recreational runner at 57.

[@philo0]

I only ever run 5k and 10ks and did my first half this year. I have only ever ran fast when I run (2x a week) and need to start running slower for longer. My 5k pb is 18:40 and I did the half in 1:30:40 with always running fast when I start and slowing down considerably at the end.... so here we go on the zone 2 run journey running longer slower runs.

[@dasdWARf]

It would be intersting to see where your optimal rer stands in relation to your aerobic threshold to have a comparison between Inigo and Seiler's zone systems. If I guestimate you seem to be over Seiler's aerobic treshold at optimal rer?

[@GaryJahman]

8:50 😂 I was chuckling too

[@wavesnowaves]

One of the most important things is not moving in an out of your lactate threshold level on a Z2 run, as over the run your body will take longer and longer to adjust again. By all means start super slow, or even end at a Z4/5 pace. But there needs to be a continuous block without going under or over.

[@drewpace7]

I just started Zone2 training for running and cycling a month ago. The hardest part is having gone from running in the 8:30 mile times to almost 12:00 mile times. I'm already starting to see it improve but it's not a quick thing and it's kind of boring. I recommend audio books or music.

[@slowloris1847]

I started zone 2 training specifically about a month and a half ago. Injuries were piling up and every run seemed like a race. Now I do 3-4 zone 2, a hills/intervals session and a fast/threshold one. Injuries holding off so far and I have more energy overall. From a numbers standpoint I've gone from 7.00/km at HR145 over 10km to this morning 6.15/km at HR141 over 15km. So, that is something! Plus, I'm enjoying all the runs more - even the fast ones!

[@andrewwastaken2]

I started training in Zone 2 maybe 5 months ago? From zero running experience to today training pure zone 2 my other run buddies are shocked at how quick I am progressing. Also its easier for me to get out and do the workout knowing I wont be so depleted after.

[@90rock1]

Interesting topic. I've almost always done my weekday runs early in the morning before I've eaten anything. I had thought I'd gotten myself reasonably adapted to using fat as fuel. However, I recently ran a 21k trail race with over 1500m elevation gain and I carb loaded in the days before and sucked down glucose during the race. I felt really good and ran the mountain course better than I expected. I was surprised and began considering how I might have been missing the mark on not fueling enough with carbs. I'll have to think about these ideas more.

[@jamesascham]

I'd be interested to see how fat oxidation in exercise is improved with low carb diets. How accurate are the formulas for calculating zone 2 HR in comparison to lactate testing etc.?

[@MrJohnno89]

Every run in my training block is fasted apart from my Sunday long run and my 2nd run on Friday afternoon. And I must say I perform so much better in the morning fasted then I do on the 2nd run Friday arvo, after work. And Sunday long run is prep for the race.

[@cpm4317]

It's important to note that you will only reap the zone2 benefits if you really do your 3-4h z2 peer week - consistently over time. For most people it's not worth it because we don't have the time to feed in 3-4h z2 a week and then still have a couple of other workouts. Z2 is for people that do have a lot of time.....

[@cospinan]

Great video, and it's great that you address zone 2. I think you should focus on information directly from Inigo San Millan. for runners, the best adaptation is to increase mitochondrial volume density and the ability to clear lactate. I know Inigo has a lap at the U, and they do test and advise athletes. it would be great if you contact him and ask about his concepts for runners.

[@ShervinShares]

I love your channel

[@SuperFuzzyDunlop]

The consensus around zone 2 training being effective is pretty overwhelming at this point. What I find a little irksome about it is that if you're logging the kind of mileage it really shines/even becomes necessary, for me anyway it becomes a pretty tedious and unreasonably time consuming way to do the majority of my running. And if you decide you decide you don't want to do the majority of running at Z2, there is a steady stream of experts and fellow runners telling you you're doing it all wrong By far the biggest % improvements to be made by amateur runners can be found by simply running consistently and eating/drinking well over a period of several years. The vast majority of amateurs probably won't reach even reach let's say 80% of their potential on this basis alone, so for there to be such a widespread focus on the sort of rigid optimisation that can rob an amateur runner of their enthusiasm for the sport over a couple of measly % seems misguided to me

[@ImprezowyKotek]

I spent last winter runing trails in ZONE 2 for WHOLE 3 months. In the weekends 2-3h sessions not looking at pace, only kepping HR under 150 bpm. At first it was hard to move soooo slow. I had to walk a lot. However in few weeks not only I was getting faster, but also my regeneration was better. Then it took me 5-6 weeks of specific marathon training to do 3h 24min maraton, when my previous PB was 3:57. Now I mantain that zone 2 by bike rides or runs without breakfest. I also cut carbs in meals on those days to make body use fat and lactate more. Most runners should start from building a solid oxygen base, that was I was lacking before.

[@jsacodes916]

It’s really kind of mind boggling that there are so many people going out to run, running with their HR WAY too high…and typically for WAY too long. You’d think that in the year 2024 this would be more mainstream knowledge. And yet, it is just as bad as it was 30 years ago. The only difference is this information is now much easier to come across. But for some reason most people can’t let go of their need for running fast…even if it is counterproductive to their health goals. Thanks for sharing your training info. In the next two weeks I’m heading to do a VO2 Max test, the ReR test and a DEXA Scan. Doing this so I can train for my first 50k…and do it right.

[@TRIQx1]

Should you eat before training in zone 2 or just eat carbs before. Will your body adapt to use fat if you train fasted? I do boxing so it needs to use carbs in a match not fat right?

[@standcontractdelta8120]

my zone 2 is probably 5:30 per km, 2 months in the making. I don't think I can wait 20 years, I will just do it for cardio fitness and if I improve, fine.

[@victormegir3041]

I have a BIG question. Is fat oxidation related to the working muscles of the activity? Do you have different fat oxidations for running and cycling? Can I improve fat oxidation for the purpose of running by cycling really slow? I could have a hard running session but then do some zone 2 cycling? Will that help me? Is it wise? I am greedy and I want to do more zone 2 running but also more threshold efforts. I think that being greedy is bad though

[@user-so4lj5ic7j]

Stephen, interesting vid. I'm confused though. If you are doing these z2 runs for 45 mins, what pace do you run the rest of your miles in the week? Lets say youre doing 100 miles week's..im guessing you're doing 20 miles at threshold/vo2 max? So what are you doing the other 80 miles at?

I did alot of high intensity training for the last 10 years. 5-14 sessions a week. And now I‘m here to tell you, if I want to run at Zone 2, I can run for two minutes extrmely slow 9:00/km and the I have to walk for 30 seconds to let heartrate drop. For me it‘s fun but for alot of people it‘s too humbling and y‘all start to run too fast again. You HAVE to stay in the zone though. Let your ego at home.

[@stephena1639]

i had my lab test (V02 max and Lactate threshold ) done in Bath Uni a couple of months ago (£140) i received a 14 page report setting out my correct zones, RER inc. it gives me training pointers how to improve both my LT1 (top end of zone 2) and LT2 (when lactate cannot be controlled by the body). i now know what my ideal zones to run in. i am an older athlete, 61 i would highly recommend getting tested as we are all individual and my coach suggested the 180 minus your age "119" bpm (is no good for older athletes) but my top of zone 2 is actually 145 bpm.

[@tri0xin]

I've always wondered how this works for those of us low carb folks. I typically eat less than 30 carbs a day and run 10 miles every other day(7:30 a mile'ish). These are typically 75 minute runs with a 160average bps. I'm 49 years old. I've been mostly low carb for 15-20 years. I guess the best way to test is to run for 2+hours and see how I feel?

[@JoshPitts530]

Before I discovered zone training, I thought older runners were just slow. I get it now!

[@sojournern]

So I think a fast walk might get really slower runners into zone 2. And it depends on how often you run. If you run 5-6 days a week yes, some of that should be zone 2, but if you run 3 days a week you do other things, like walking fast that might get you into zone 2.

[@stephenscullion262]

I’d say so yes and that’s the idea of “most people” won’t want to do that, and I actually get that. BUT most people aren’t always willing to do what could eventually separate them from the pack

[@heatherbriggs7818]

Absolutely us slow runners can get into zone 2 with a fast walk. Then over time it requires some short 15 sec jogs to get there. Now I'm at half and half and my mile times are a full minute faster!

Stephen, I live in an area which is impossible to avoid hills alot of the time. Can you do a zone 2 and 3 video on what time do with heart rate?

[@boblamb2161]

used to do 20:4 intermittant fasting. would run an hour at the end of the fast. would bonk after about 25-30 min until I started taking about a 1/2 tsp of coconut oil before the run. could run 1-hr hard after that while fasted for 20-hrs. MCTs in the coconut oil fed my brain (liver was too depleted of glycogen after 20-hrs of fasting to feed the brain and I couldn't metabolize fat quick enough to feed the brain while runingn hard for an hour). Muscle glycogen can't be shared with the brain so when your liver runs out of glycogen, you only can run slow if relying on fat metabolism, or you can do what I did and take some coconut oil and you can go fast fasted. Corn starch or ucan superstarch works good also and no upset stomach with either one.

[@na-dk9vm]

Bob, if someone isn't doing fasting, but they still have a spoon of coconut oil before a run, would it still help?? Would the MCT oils still give a boost in energy/endurance

[@karenr.349]

If I do my long runs at zone 2, I don't reach the cut off time of my race. Any thoughts? I started running in 2003. Now I am 40. I ran 2 Marathons and I am slow. This new zone 2 trend is making me depressed 😢 Because I think you are right and I am even slower than I was in 2016? Can I add an extra session as a brisk walk at Zone 2 during the week and keep my long runs on the weekends on the cut off time pace? I am training for a half IM in 16 weeks. I ran today 10km at 7:15 min/Km which is already above what I wished and was Zone 4 😢

[@kennydroid2254]

Since pace is prob so low for most people in z2, could walking be benefitial?

[@JesseStarks]

This is a perfect starter for people who are overwhelmed by zone2, MAF, low heartrate, yadda yadda. Like you said, simplest to assume your fat burning is shit, and start really low. So many vids out there get super technical and complicated and that’s cool - but for most people, just go slow as hell and abide by a conservative HR to start. Maybe 130bpm +/- 10bpm. Then stick to that and see how pace at that HR improves over weeks. Been going for several weeks and landed on this approach myself. Love seeing someone who’s been at it for 20 years drop 6 minute miles at 144 HR! I used to run at only blistering speed. So glad I started slowing down.

Respectfully, we don’t lose lactate from the body - not sure what you mean here? Also, it doesn’t become waste? Did you mean the accumulation of hydrogen ions?

[@michaelgodsmark2008]

Does anyone know what lab tests he's referring to? Just not sure what to search for when looking at companies local to me (NW England)

[@crayontom9687]

Lactate testing. You’ll get onto a treadmill and the speed will gradually increase with lactate readings taken every 4 mins or so. I did one in the North West earlier this year, was £60. Worth doing

I am very fat. Should I prefer aerobic running to make my body use the fat because I have so much of it? I don't want to loose weight or so, just make progress in running faster. I don't think my body can store as much glycogen to match the amount of fat I have.

[@hikerJohn]

It's all about moving your lactate threshold farther to the right so you can burn fat all the way up to 80% of max HR. If you really want to understand this, watch the YT video *"The Physiology Of Endurance"* or buy the book *"Training For The Uphill Athlete"* It's good to actually know what is going on with your metabolism and just WHY coaches are saying what they are saying.

[@frankgeppert8972]

I practiced zone 2 training a while and it did not help to get better. I am sure, you can get to a point with that kind of training. But if you achieved it, you have to do a lot of intervals, sprints and tempo runs. I also tried the pipolar approach but the pyramidal training works better for me. I mean: I do running and swimming and I have 4 running sessions per week. One is a long run between 15 and 20 km. This is the slow run, the zone 2 amount for the week. Then there are 3 more between 4 and 8 km each and they all have to be faster than that, otherwise it gets hard to get the medium and strong zone runs. Many of the scientific findings are researched on professionals, running 3 times the km than I do.

[@markvickers9677]

I'm new to running and seen a lot around Zone 2. What I don't understand is I have a garmin and Zone 2 which is classed as easy by Garmin is a Lower heart rate than the calculations I've seen. The heart rate calculations comes out at Zone 3 on Garmin. Should I be doing the Zone 2 on the watch or work to Zone 3? Thank you.

[@st4331]

I recommend using Karvonen method to calculate HR zones, then adjusting the Garmin settings, which are generic.

[@jamesroberts6370]

I’m in the same situation my zone 2 is between 115 and 130 ??

[@rafaelodossantos4210]

Your hr is so low at high speed amazingg

[@wrusst]

Pretty sure he said 2 x to hold it and 3x a week to start move the needle forward

[@Cloppa2000]

I am so confused with zone 2 and aerobic training! Zone 2 I see for fat burning is 60-70% HRM Aerobic training using Karvonen is like 70-80% HRM So is zone 2 for fat burning and zone 3 for aerobic training? I tried MAF training to get fitter but after 9 months my MAF tests were not 1 second better. I now think it was because it was too slow! Was I using the wrong zone to get fitter? My MAF zone was 60-70% of my HRM. So is Zone 2 just for fat burning and zone 3 is for improving aerobic fitness?

[@rad6918]

Yeah im also little confused but im 39 so ill do 180-39 = 141 bpm Ill do 48minutes in this ZONE2 BPM and then ill do 12minutes in ZONE3-4 at 160BPM +-.... I already did similar but not controling the BPM's and usually running at Zone 3-4 most of the time! ill probably do this 5times a week! Lets see how it goes LOL

[@rad6918]

i believe this way i fat burn on the Zone 2 but also challenge myself on Zone3-4-5 like for fast 12min sprint after Zone2

[@jhunt5578]

Im all for zone 2 running my confusion is just where exactly it is. There's 3 zone methods and 5 zone methods. Ive heart 60% - 70% off maz heart rate (MHR) which seems too low. But Ive also heard 65% - 75% off MHR and also 70% - 80% off MHR.

[@riderboys8635]

I agree brother..its all over the place..so just maintain the middle..70% heart rate,, so i cant be far off

[@Eric-bh7jy]

I run zone 2, 2-3 days a week for 45 min for the past 3 months. My pace has gotten even slower!! Help!

[@benhur2265]

I found information that it really helps when you run weekly 7 hours and 4-5 runs each week. If still no progress, Then maybe sth wrong with nutrition, running form or enough sleep. after 3 months you may see some improvements thats because zone 2 pushes cell nucleus giving orders to mito’s to increase their numbers. It just happens after a while(3-4 months ) which means now you have more energy plants for carb cycles and lipid synthesis so that less bpm would enough to carry out oxyg to the muscle cells. After you reach plateau then you may add some tempo runs or intervals, that kind of sessions force mito’s getting larger in volumes now you have more and bigger mito’s. Hope that helps.

[@jackpiper3684]

So is zone 2 running still beneficial to someone who specialises for 5k distance? Should I be doing all my easy runs in the zone 2 HR zone or should I just go at what feels like an easy conversational pace?

[@jackpiper3684]

Mainly because if the main benefit is becoming more efficient at utilising fat as a fuel I don’t know how useful that is because you won’t reach a point of carb depletion in a 5km. Or is it still worth running easy runs in the zone 2 for the benefit of the recovery.

[@dresden_slowjog]

5k and 10k runner here. Yes, Zone 2 training helps on short distances, too. During Zone 2 training you will not only increase your number of mitochondria, mitochondrial efficiency, and increase your metabolic flexibility (BASE BUILDING, mitochondria are your "furnaces" to create ATP for energy AND reuse/clear lactate. The more you have the better.), It also improves LACTATE CLEARANCE, plus reduces RISK OF INJURY. I still see my 5k PB drop over the years (at 45 y.o. now, started running 3 years ago, 21:32 PB), and I know a >70 y.o. who runs 33 min 10 km races. Out of Corona lockdown boredom he ran long zone 2 runs every day. He shed every ounce of fat, I think he went overboard, though! Googled for "Zone 2 mitochondria", and like the first hit sums it up nicely, an article by San Millan: www.trainingpeaks.com/blog/zone-2-training-for-endurance-athletes/ "Besides fat utilization, (slow twitch) type I muscle fibers are also responsible for lactate clearance. Lactate is the byproduct of glucose utilization which is utilized in large amounts by fast-twitch muscle fibers. Therefore, lactate is mainly produced in fast-twitch muscle fibers, which then, through a specific transporter called MCT-4, export lactate away from these fibers. However, lactate needs to be cleared, or else it will accumulate. This is when Type I muscle fibers play the key role of lactate clearance. Type I muscle fibers contain a transporter called MCT-1 which is in charge of taking up lactate and transporting it to the mitochondria, where it is reused as energy. Zone 2 training increases mitochondrial density as well as MCT-1 transporters. By training Zone 2, we will not only improve fat utilization and preserve glycogen, but we will also increase lactate clearance capacity, which is key for athletic performance."

[@MrSuperstevie]

Yes absolutely. Just because you won’t reach carb depletion doesn’t mean that aren’t still relying on fat for a substantial part of your fuel mix during a 5k. Chances are an easy conversational pace ought to put you pretty close to zone 2 anyway

[@61js]

​@@jackpiper3684On a 5k you don't want to burn fat. Glycogen coverts to energy more efficiently that fat. It needs less oxgen.

[@ragreenburg]

I am a bit confused here. When you say "It teaches your body to burn these other fuels" which are fat and lactate, how does that work? If I were to never do any Zone 2 work would my body never burn either of those? Then if I started doing Zone 2 all the time for a while my body starts burning the fat and lactate? Thanks for the nice video, would love a bit of clarification on how that works. Sorry if you said it in the video, I think I listened pretty well but it's possible I missed something.

[@stephenscullion262]

Essentially if you don’t develop your bodies ability to utilise fat as fuel, you’ll use carbohydrates. Body can only store about 1 hour 40 of carbs if you’re running at “max effort” for 1 hour 40, obv not max effort.. so of course developing the ability to utilise fats is fab.

[@ragreenburg]

@@stephenscullion262 Okay, thanks for clarifying! That makes more sense now.

sometimes you are using mins/km and other times mins/mile and it hurts my tiny brain 😖😖😖

180£ on a Saturday night? Not for the last 20 years! 😂 I'm American, I shudder to think what this would cost here in the land of preventative care being a luxury, but I'll look into it. Honestly, I'm more concerned about zone 2 as it relates to cardiac efficiency. I'm an ultra runner, I munch on donuts and quesadillas while I run... it's a reward for covering the miles! 😂

[@vikroy3777]

They say zone 2 'works' if you really up the mileage and I can believe it. Who has time to spend hours and hours jogging at this pace? Not many... May as well take up cycling and make a day of it imo ... go somewhere nice and slow on the bike, stay over etc
