Need thoughts on HR data - for a guy running across the USA

is that the approx HR of a watch sitting on the desk of an RV being driven around based on vibrations of the surface?

normal HR is 60-90. Above 100, it is considered tachycardia which would be consistent with a brisk walk for someone who has a HR of 70. Is that how fast this guy is going on his 40 miles per day efforts? 40 miles / 16 hours per day is like 2.5 miles per hour which is consistent with a moderate walk.

Seems legit to me

This has potential.

Mmmh sounds interesting.

I can see that the heart rate goes up a little bit when people show up but that should settle again after a couple of minutes.

No idea what the heart rate should be, since I did these things without a heart rate monitor. But I would think that the heart rate should be fairly constant.

Sounds like you’re mad at this guy for walking occasionally. Anything else mundane you’d like to bring up?

Clearly the guy has social anxiety so his HR jumps when he’s around other people.

Actually, if someone in Iowa wanted to track him down like that Kansas Letsrunner did to catch that one RV fraud, then we could put this question to bed, and stop doubting him if he’s really running.

Heart rate from watch sensors are notoriously inaccurate. There is a very good reason why chest strap heart rate monitors are still used even with these stupid heart rate sensors built into watches. There is nothing to see here.

No way 109 is accurate for a 50 mile run. At some point HR always creeps up due to fatigue if he was actually running. Are times of his runs posted?

At first glance, you're overthinking it. You can see his pace is quite slow; he's doing little more than shuffling along at about 10- or 11-minute pace. That won't require a very high heart rate, and that assumes his Garmin Enduro is pretty accurate. He has also enabled his cadence display on Strava, and you can see he's consistently about 160-165, which is normal.

You can compare this data to Mike Wardian's, who's running the opposite direction. There's no cadence data for Mike's runs (I think), but he's running roughly the same pace per mile, and his HR is in the low 120s, with some stretches near and under 100. So, maybe 10-15 bpm higher most often, but not different enough that it would make me doubt Greg's data.

Yes, detailed data for all of his runs is on Strava.

good points Makes Paper.

hr data is really tricky. if you're putting in extreme volume you have to remember your max hr goes down and typically everything else along with it, except for resting hr. my threshold hr was typically around 185-188, but in a block of very high volume i might be putting out the same power at nearly 20 beats lower. lots of fatigue so maximum efforts wouldn't get my hr anywhere close to my typical max of around 205-210. i'd be lucky to flirt with 190.

the size of a person matters a lot too. typically lighter people will have higher hr and larger people will have what looks like a strangely low hr (mouse to elephant curve). same goes for younger v. older, higher hr in the former.

not sure the age or size of this runner, but the hr data provided thus far doesn't raise major red flags for me.

He's running 10 minute miles on his ownand 8 minute miles when others join him.

Good post. Clever handle.

I'm in an agreement that older watch sensors have been inaccurate. The newer Garmin's that have come out have shown to establish a decent baseline. I've taken this into consideration and asked if Garmin Enduro is legit.

Brisk walking makes sense but there should be some spikes in HR to account for elevation changes & weather.

His runs are posted on Strava.

I did a quick check and I am not seeing anything strange.

He is also a little bit behind schedule if I see that right.

Great info. Just glanced at Michael Wardian on Strava & will compare the two runners. I'm using their last 6 runs and just adding up Strava HR Range zone.

The first 6 days of their journey's.
Percentage of time Wardian spent in HR zones Z1 with a Coros = 65%
Percentage of time Nance runs in HR zones Z1 with a Garmin = 38%

For their last 6 runs.
Percentage of time Wardian spent in HR zones Z1 with a Coros Vertix 2 = 62.5%
Percentage of time Nance spent in HR zones Z1 with a Garmin = 97.5%

Hmm...

He's usually 40 miles / 11 hours per day on average. Agree on the brisk walk.
