I'm not sure why more research into heart rate response in older well trained athletes has not been done.

We keep getting calls for trained cyclists to do "studies" at the local university and any time I try to volunteer they say that they can't take anyone over 50.

I suspect the under 50's have been studied enough and there would be some interesting things to discover with the over 50's crowd with respect to well trained athletes.

At 62 I have the same max heart rate (within a couple of BPM) that I had at 50 around 188-190 which puts me about 30 away from the formula suggested value. Threshold a few BPM lower than 10 years ago.

I am 55, typically run 35 miles a week. on yesterdays 16 mile run I averaged 180bpm, and on a sprint at the end of a 5K I topped out at 210bpm.


Hi Joe,

I am a 36 year old competitive mountain biker. I generally race in the top 10 in my age category, but I am looking to move up to the top 5 (age Cat) and possibly even get into the top 10/ top 15 overall.

I have been reading several of your articles with interest. I train about 10-12 hours a week and have recently finished your Cyclists Training bible and I monitor my training with Training Peaks. I don't have a power meter.. and cant afford one yet!!

I race about twice a month and my general distance is about 60km Mountain bike Marathons, but I also do XCO on and off. My challenge is around getting my blend of intensities right.

I have recalibrated my HR monitor as recommended in your Cyclists training bible using your tables. According to Training Peaks my heartrate for the past 3 months is:

Z1: 36%
Z2: 26%
Z5: 3.5%
Z6: 3%
Z7: 4.9%

What I am trying to establish is, am I training in the right zones at the right intensities with that blend? I read another of your articles saying that intensity trumps volume almost every time. Do I need to spend more time in higher zones and less in 1,2 and 3? Am I doing too much volume at low intensity? Thanks in advance.

I am 69 years old and run and cycle. I have a max HR of close to 170. Following running a half marathon race, Training Peaks gave me a new LTHR of 163. I updated Training Peaks accordingly and my HR and Pace zones seem to match now. My question is with a Max HR of 170 shouldn't my LTHR be lower than 163 because using your 7 HR zones for running and LTHR zones 5b and 5c are above my max HR.

Joe Friel

Franz--Heart rate is unique to the individual. And the amount of time spent well above LTHR is so minimal as to be a non-issue. Just press ahead with your training.


This discussion of heart rate got me thinking, since mine has pretty much always run high during exercise. I'm going to buy one of the books, but also wanted to post here in case other forum readers have experienced the same and can weigh in.

Has anyone ever experienced where rTss is consistently higher than hrTss for all running workouts, and does anyone know what this means?

Could it mean that my HR zones are set too high? I did a 30 minute test, and the average HR for the second 20 mins was 189. Now on the one hand, I have observed HRs during crits a few years back that were up around 210, so it's not out of the question, but one the other hand, it's pretty high relative to recently observed maxes (which were mid 190s). Maybe i was too fatigued, or fighting off a virus, when i tested?

Alternatively, could the running zones be set too slow? It's been a while since my last Run TT, so maybe fitness has advanced since then.

Appreciate any thoughts!
