Jason Cherriman is a 38 year old elite runner from Leeds in the UK (Strava: / strava ) His current marathon PB is 2:21:51 and he is trying to break 2:20 at the London Marathon this Sunday!
In today’s Extramilest Show, he shares many recommendations for marathoners of different levels who are looking to improve. We take a deep dive into heart rate training, aerobic development, measuring various data points, heat training, tapering and much more.
Background stats Jason:
* His max heart rate tested in a lab is 198
* His vo2max during the test was 70
* MAF hr is 147 (180 - 38 + 5)
* In the past 10 weeks he ran an average of 111 miles (179km) per week, that’s about 14 hours a week, 2 hours a day
* 75 to 80% of his runs at low HR (140 or below)
* His average HR during marathon races is 174 to 177
* PR's - marathon in 2:21:51, half marathon in 68:55, 10k in 32:05 and 5k in 15:37.
I learned a lot on today’s episode and made many notes for my own upcoming training blocks.

I went from a 2h19min half marathon in 2018 to a 1hr42min half marathon this weekend. Did this by cutting ALL my fast runs (Which used to be about 90% of my runs) and doing only runs at MAF heart rate. Been training like this for the past 5 months. My times are nothing spectacular for sure but still better than anything I could manage in the past and definitely thanks to low heart rate training. Still at the early stages of training by this method and I still foresee a lot of improvement in the coming months.

@lastfearboy 5 лет назад

Hi can i ask you just continue to run at a lower bpm without looking at the pace right?

@kotieerwee2593 5 лет назад

@@lastfearboy For the occasional races I am more focused on pace, but for my training I only look at my bpm's. I do however allow a play of about 5 beats up or down from MAF depending on my fatigue levels.

@Quincycle 2 года назад

What I don't understand is if you're always running at MAF HR for months, do you just go straight into race date and then run much faster at a higher HR? Surely you need some conditioning at your race day HR?

@bendigeidfranemmanueljones5694 Год назад

I did that in 6 months not doing maf. Anything works for beginners.

@balachandar548 Год назад

@@Quincycle with low HR training you avoid injury, can go on and on without getting injured. I did sub 2 HM training at 7km/hr that's 8:34mins per KMs. Trained for 6 months, no injuries feels good actually. My runs were 1hr to 1:30hr each.

@Amanda.c91 3 года назад

Just signed up for my first marathon yesterday! Been doing MAF training for a bit. All my runs so far are 10+ miles with no aches or pains. Just some soreness in the glutes haha but feel ready to run again at the end of each run! Keeping that HR in the 140s and enjoying every second of my runs, total bliss training this way and fasted.

I've just started maf training so far I've done a week and a half... My garmin is telling me I'm detraining lol good job I don't pay attention to that... I have a overuse injury to my achillies which is why I've started on this way of running and altho it can be frustrating going so slow its also very enjoyable and I can't wait to see me get faster on the same heart effort in the weeks to come.. I love listening to all the podcast on this and also nutrition :)

@richardmiddleton7770 2 месяца назад

You have to occasionally test if you can still hit your max HR. Even sticking to zone 2 training only it can make you fatigued which will bring down your max HR so you will be running at higher and higher percentages of your max. This will happen if you always stick to MAF especially believing you can go 5 beats above if your advanced. It's better to stick to a pace and let your HR be lower rather than always be chasing the upper end of the HR formula. I believe the MAF formula is better as a MAX HR number and to try to stay 5-10 beats BELOW that.

@advex4428 5 лет назад

I have to totally agree on the Garmin wrist heart rate monitor. I'm a triathlete and figured out that it has problems distinguishing vibrations from the steps from actual heartbeats. After I also had discarded it for running, figured out that it works very well on the bike. But recently I went over some cobblestone section at low heart rate, but the watch showed hr go up crazily. So to specify, it usually works great on the roadbike, but I would assume that mountainbikers run into problems, too, due to surface.

@FlorisGierman 5 лет назад

@advex4428 10 месяцев назад

@@ozz3790Oh your actual question was, what did I use during a run after discarding it for that. A cheapo garmin with a cheststrap. It worked well. But the current Garmin works well on the wrist without a cheststrap. Cheers

@giovanbattistafichera8439 4 года назад

I have exactly the same model and at low temperatures the readings are all over the place. I suppose that's because my veins constrict and the watch has trouble picking up variations. I have a threshold run with 115bpm throughout with spikes close to the real HR to prove it. After that disappointing experience, I just bought a wahoo chest strap and now all is fine.

@dcutl 4 года назад

Giovanbattista Fichera, sorry to hear that the M430 doesn’t work for you in cold weather. Glad that you corrected the problem with a chest strap. I have never had a problem.

If I run 50% of my marathon at 148-153 and 40% at 154-158 and 10% at 159-165, what makes sense as training heart rate? MAF rate+5 is 128, which is no where near race rates. Garmin has me at low Aerobics till 142. I feels comfortable running at 138 for a long run.

How do you related MAF heart rate(and pace) to a race heart rate(and pacing strategy)? It's common to see runners running a marathon @ high zone 2 to low zone 3(which is around MAF HR). But elites like Jason are definitely running much higher than that.

@krruns4165 4 года назад

Hi, you would be looking to run a marathon at between 80-90% max HR. For me, MAF HR would be more like 70% max HR. So, in summary, you would be looking to race a marathon at a higher intensity than MAF HR.
