Seth James DeMoor: Crazy low HR

His running 9 minute miles is like a 3:30 marathoner running 13-minute miles. Not that surprising that it is barely above walking effort for him.

What percentage of his max hr is that? Maybe if his max is very low his easy pace hr should be very low as well?

Are there any guys on Seth's fitness level (that share this type of info) and run some of their Easy/Recovery runs as easy as Seth?

1). 9 minute pace is too slow for a 66 minute half marathoner. 100bpm is not in any aerobic zone and the pace is so far away from the mechanics of running a race, it does nothing for him.

2). We don't know his max Heart rate. HR is only relevant as a percentage of max.

3). He's using a wrist-based HR monitor which is inaccurate.

4). He also just made a video explaning why he doesn't train by HR.

Hold up is this same guy that was crying when Joe Gray smashed his FKt because he couldn't go to Golden trail champs? Give me a break. Stop making posts about yourself dude. Honestly HR monitors on wrist are completely bogus. I did a tempo once and it said I was 125avg and I could taste blood the entire way, so clearly...

Good to know. Don't follow his youtube much. Interesting.

No it's not, and my watch is never that off. 125 on a tempo? I did 125 average on my recovery run today at 8 min pace. Garmin forerunner 245.

He's 35 or somewhere around there so based on 210-age that would be 175. so 62 percent. But I highly doubt his max is that low. Maybe 200. with that than 54 percent. Either way very low.

For the 1,000,000th time, wrist-based HR is not that accurate. Especially if you're looking at someone else's run. You don't know if he bothered to let it lock on, if it was tight enough, etc.

But he's running slowly enough that ~120 (within the range of error) is believable.

I honestly think you’d be hard pressed to find others who train that slow at that level. Seth appears to follow Lydiard like a cultist. Most guys his level train around 100-110 at 7:30ish if I had to guess

I follow Seth's channel on and off. He doesn't train all his easy days this easy. If you look at his Strava, you'll notice this was his first run of the day. He also did another 10 miles that afternoon at 7:29min/mile where is average HR was 120.

Additionally, the day before he ran a 25 miles mountain run peaking at 14,000 ft, so it's completely understandable to see the Strava activity be slow as it was truly a recovery effort for him. Not to mention this was during a week where he topped 130 miles.

I do appreciate those in this comments section that are slamming Seth for this one run as if he's got his training philosophy wrong though. Jealous LRC users never cease to amaze.

im indifferent to seth's youtube antics, but that HR reading impresses me.

I wouldn’t over analyze Seth’s heart rate on runs with his wrist based heart rate monitor. Even he doesn’t pay attention to it. Though he has ordered a chest strap heart rate monitor to satisfy the fan boys who want heart rate information. It has been coldish here Denver and if he doesn’t put on the watch on correctly, he’ll never get a good pulse reading, especially with with his small wrists. Also the 10 mile was triple sandwiched between another 10 mile run on the same day at 7:27 pace, 25 mile winter ascent of the 14er Mount Evans and a 23 mile run around Denver. He’s getting some road work in for a YouTube runner.

I can believe a HR of 110 for a 9min pace easy jog. I'm more like a 70min half marathoner, 28 years old, and at 9min pace I'd be surprised if my HR got over 120. so not far off and he's a tier or two above me. my tempo HR is about 170, marathon around 160s, easy runs at 7:20 pace maybe 130.

but if you check my strava it says my HR is always 150-160 because I use an optical HRM on my wrist and it's not even the slightest bit helpful as data

Could you post the video where this occurred? I think you are full of sh!t. Letsrun posters (idiots like you) started some threads about it is all I remember.

As for heartrate, mine is between 110 and 112 when I jog at 9 minute pace and I am much much slower than SJD.

I wasn't hating on Seth. I like the guy.

There is Nicolas Navarro (2h09 marathoner), Jo Fukuda as well maybe

Here's a 1h jog with some straight lines

Oh, baby! Maybe for an additional $3.99 per month, SJD subscribers can get a buttered toast emoji shaped like a heart that beats really slowly? Clearly, he was doing his run in some new prototype super flat that only weighs 4.5 ounces since anything over 8 ounces in his size is hot garbage akin to wearing cinder blocks.

I've gone through three of those wrist hrms recently.

I can at best only say that one of them shows a nearly accurate resting pulse rate occasionally and none were even close on running rate.

The last watch, a TicWatchPro (at @$300. Is completely bonkers. Does nothing logically or accurately. Completely useless.
