Awesome info and 100% mirrors what I learned in the book "Training for the Uphill Athlete". I used to only train at threshold (didn't have any concept of that at the time) because like you said "that's running". Since I neglected base building I never developed a base. Now I'm building that base and doing threshold's once a week. Without trying that's loosely put me in the 80/20 range. Running at threshold is such a freeing experience. On the flats and slightly downhills I feel like I'm floating and almost always enter a flow state when I'm not on technical terrain. It's very seducing and makes me want to do it all the time. Then when I go to my base building runs it feels like I'm slogging because my base is so low and therefore slow. Anyway, good luck in the race.

As a miler and 800 meter runner from morocco and sometimes a 5k runner we have to do these runs on our easy days more aerobic threshold pace. I run a 4:09 mile and 3:51 1500 so we will do 5:20 pace for these runs slower if needed but we never run more then a hour. I love threshold runs, just our coach is definitely more careful and makes sure we always feel well if we’re not we’re jogging. Threshold is definitely a major system.

Once a week I try to do speedwork at full blast for 400m (+170 HR) or even shorter distances lik 20sec sprint reps.

@@goodyeoman4534apologies for the long answer, but I happen to be sitting at the WC...the word "threshold" refers to regions of lactate production. Knowing what "threshold pace" exactly is at a specific time (important) requires a lactate measurer ($$). Not everyone can, but we can also have a good idea of when we are entering that zone purely by effort feelings or heart rate. Heart rate is a very variable factor (temperature, quality of sleep, stress, wind), so this is why Scullion is putting so much effort in this video in referring to "effort", and not asking you to buy an electronic measurer that requires 40€ per month of stripes to know. The pace will differ depending on how long your repetition is and how quick you are, but the effort should remain the same (~85-90% of max) . You should investigate on your own to learn how that effort feels: it should be hard enough to feel slightly uncomfortable, but you should feel fresh enough at the end of the workout to be able to start another one in a few hours. For example, when doing 8 x 1km with 60-90s rec, instead of going at 10k pace, do them at half marathon pace. See how you feel, then repeat them at a slightly higher pace the following week, and adjust. It is about learning how your body feels at threshold, to be able to bring up your level of effort no matter how the external circumstances are.

@@chrism589.Yes, a test. I visit once a year a threshold test in a lab. A test can give you the confirmation that you train at the right intensity. I once witnessed an experiment where only 3/10 amateur runners guessed their threshold somehow right, when they did blood lactate testing. So either it only confirms that you know your threshold or it corrects your assumption. Would say worth it. Have a good run.

I feel like the 3x 4km at LT2 is a really good session to see how ready I am for HM race day, since for the last hour of the race I'm pretty darn close to LT2, just tip-toeing that line between being good and losing gas.

A few years ago when I was running really well (60-70 miles / week) and doing a 3 month base phase, I would do 2 harder runs every week, and a 2 h easy long run to round the week out. First was at LT1 for 1.5 h and the second run 2 days later was LT1/LT2 for 1 h. I grew to really love the second run and after 2 months of this, I was absolutely flying and to finish the base phase, did a 2 h harder run slightly below LT1 effort (ie slightly below what would have been my then marathon pace effort) at a pace that was much quicker than expected. I was FLYING!!! My next phase was a 12 week 10 K training plan and I vividly remember doing my first tempo session for this (4 X 1 mile, tempo pace, off 5 mins rest...pace was maybe a bit below 10K current race pace) and I was really taken aback by how hard the effort felt, given how fit I thought I was. Basically, while super fit and fast at threshold, my body was so used to running at that effort that stepping it up even slightly still felt challenging. But as I progressed over the weeks with the added tempo running and some VO2max stuff, my threshold pace increased even more. So as Steven says, variety is key and even though threshold can feel so enjoyable when you are well conditioned, don't forget to run the faster stuff!

There are some "tricks" that you can do with a treadmill and looking for your heartrate increase over time (1h). However, the easiest and most accurate is to get it properly measured out at a sport center. It requires quite accurate hrm and a capable person to interpret it. Especially for endurance runners where the test needs to be extended because they're so well trained for the different zones.

It's best to just get familiar with what you can handle for X amount of time. Go for a hard 45-50min run and keep your HR at a given area for the last 35-40min, since at the beginning it takes about 5-10min to have your HR settle in to the effort you're putting forth. Figure out your average HR during those last 35-40min and you should be able to handle that for a solid 50-60min if needed. Same goes for a LT1 run, stay steady and run for 2 hours. If you undershoot your effort and feel like you could have gone a little harder, then figure that in to your next session and see how you do.

I am personally someone who can run faster paces but struggles to hold them for longer races and was wondering of LT1 was the missing ingredient for strength and capacity.

When you say leg strength letting you down and what do i do to improve this leg strength exercises (heavy weights low rep) or muscle endurance ( light weight high rep) im suspicious that this is holding me back i tend to slow considerably towards end of marathon and 50k efforts even tho i train long run well i always you seem to train well and race poorly. Hr always alot higher on race day i assume thats a race anxiety issue but would this also be a reason for underperformance ?
@stephenscullion2629 ай бұрын
Hr higher can also be being fresher, and so less suppressed. But nerves and anxiety can play a role of course. Could be leg strength, or could be you didn’t train on relevant terrain. Pounding can cause physical issues that was more linked to relevant practice and not gym strength.. same for hills, or trails. Relevant practice in training. Gym would just be ensuring the areas that are breaking down, are being worked in the gym to rebuild strength throughout the build up. Training breaks the muscles down (reduces strength) but be consistent with that.

LT1 is the point where your lactate levels rise a bit but not too an intense degree. This is about Zone 3. When you go a bit faster, you'll have another noticeable spike which is LT2. Not sure how the HR fits in. I never focus on HR anymore but just go by feel, pace and time.
