Man, if true then that's a hell of a 10k time. You sure that's not on a bike though haha. The only suspicious thing for me is the HR? Avg of 124 at that pace over 10k?
That's the first thing I noticed too. Surely it's too low? That or the crappy treadmill heart rate monitor isn't reliable.
Speaking about low heart rates... i've stumbled upon something weird. I like to "analyze" runners efforts on strava - to learn something from them. Well, for some of the fast local people around here, i'm just perplexed. Some of them are running 5:0X-5:2X per mile over 5k, so 15:XX-16:XX 5k's, with HR's at ~125 BPM or so. To me that's insanely low. So then I look at another race a few months earlier, and the HR's are ~165 BPM, at a slightly slower pace. That made me do a double take.. I find that extremely odd. I know nothing about PED's, but that's the first time i've really wondered if people are doing them. Also, this happened for 2 people, who are "friends". Doesn't bother me any, just find it interesting. I wonder what someone's stats would look like if they just got on EPO or something. Or maybe they just had a serious tail wind, that'd probably be a legit explanation. FWIW, they are also fast with a more normal HR, just not as fast as this bigger 5k race with an incredibly low HR. I personally don't get how someone who is "near PR level" for a 5k effort, could run 3 x 5:0X miles, with such a low HR. I'd expect someone's HR to be that low, if they are used to running 4:2X per mile, and are trotting the 5:0X..
As for Mutumbo's friend, that's a fast pace for sure. I imagine that HR could be legit for a treadmill run, the treadmill itself does alot of work. I'd imagine it would be higher on a road/track run.
Never thought about the EPO thing for recreational runners but then again why not use? I know a dozen guys at my gym who aren't that big but are recreational lifters and use steroids regularly. Even posting their "juicy" pics and workouts on IG as if no one can figure out that terminology. Runners are ego and numbers driven so it would not surprise me at all if they were using. I would go as far as to suggest that some runners are more ego driven than the vainest of bodybuilders out there.
Would it be accurate to say that the fitter/more elite you are the closer to your max HR you can run? Therefore if you're doing 3m/k's for distance and only have a HR of 124 then you would potentially have plenty of upside???
