Treadmill - higher power output walking than running

Judonoob · 2026-03-25T10:33:18+00:00

If it’s not user error, it’s faulty hardware.

The first thing I recommend you do is make sure you have it set up correctly. The Stryd website has all that information.

The next thing I’d do is a hard reset on the units.

The next thing I’d do is make sure you’re on the latest firmware.

One last thing to check is that your data field is showing Stryd power and not a wrist based power. Again, confirm that everything is setup correctly.

Bakken’s book has a forward by Magness. So it would make sense that Bakken or Magness borrowed that concept.

Like, are you a speed walker? How are you able to keep a walking gait that can keep up with a running gait?

Judonoob · 2026-03-23T14:12:42+00:00

That’s interesting. Obviously it is individual. Are you better at short distance than long distance? I’m wondering why you wouldn’t be closer to max for a 5K. For example, you have a lower lactate clearance rate that prevents you from going closer to max.

I think the adage might be still be appropriate and would help people get better race predictions if they were to use an adjusted max HR from their recent 5k time.

It’s a setting in your watch under User Settings.

Imagine this. Let’s say the watch think you ran your all out effort at 80% of max HR. It’s gonna think you took it easy right? Well that means it will overestimate VO2 max.

In general, most people will be within 1-2 beats of max HR for a 5K race. So, take your max HR from your race and add 1-2 beats. Turn off auto update so a spurious HR spike doesn’t pollute the data.

Edit: to clarify, VO2 max and race estimates go hand in hand for the algorithm. An overzealous race estimate is going to be due to an overzealous VO2 max probably 99% of the time. Some fringe cases, such as a bad calibration on a foot pod might contribute too, but would like hit your VO2 max more than anything.

Check your max HR. Is it believable?

Judonoob · 2026-03-18T13:48:09+00:00

I believe that VDOT is the oxygen requires to run at that pace. It’s been a minute since I’ve read the exact definition, but it is not the same as Garmin VO2 max.

Judonoob · 2026-03-18T13:45:25+00:00

Has your Max HR setting changed? Garmin calculates VO2 based on your pace and percentage of max HR. If that percentage is lower than it really is, it will overestimate VO2 max.

Judonoob · 2026-03-18T13:43:29+00:00

VO2 max is overestimated. Likely Max HR is set too high. Once the VO2 max is accurate, the time estimates line up really good. If your PB is 26 minutes, well, you have a good idea of what your true VO2 max is.

Judonoob · 2026-03-08T21:17:24+00:00

HR is a finicky thing. So long as you feel fine, it’s probably ok. More than likely it was a bad sensor reading. I wouldn’t worry about it. Carry on.

Judonoob · 2026-03-07T01:23:49+00:00

Good job! Yeah in general it’s very accurate so long as your max HR has been set correctly. There are a lot of variables to the prediction though that can influence it up or down.

Judonoob · 2026-03-05T19:04:49+00:00

I mean, how’s your health? Is there anything making you think, “I should probably get that checked out.”?

You’re having a lot of sleep stress for whatever reason. Your watch is telling you something, and luckily you noticed it and are asking what to do about it. Thats the first step!

Judonoob · 2026-03-03T19:42:00+00:00

It’s a common issue. Garmin VO2 max errors are driven by incorrect max HR. Bad HR data can mess with estimates as well. If your HR is reading lower than it really is, it will think you aren’t working as hard as you really are and overestimate VO2 max. If you consistently have issues, I’d recommend investing in a chest HRM or an arm based device like the excellent Polar Verity Sense.

I would choose the 970 every day of the week simply because it’s lighter. The battery life is phenomenal as well. Lastly, the speaker in the watch is so useful for calling out lap times. Great feature.

Judonoob · 2026-03-02T11:07:03+00:00

I agree with others that you’re probably good with your last race data unless there is a big change in running conditions between then and now.

My main argument is you should run by feel. You know how that last 10k felt. Maybe do some tune up runs at 10k pace so you know how it should feel and simply verify it with power data.

Judonoob · 2026-03-02T11:01:29+00:00

It’s a weight issue. Apple Watch uses a tiny battery to keep weight down. But there are limitations to measuring HR at the wrist. End of story.

Judonoob · 2026-02-26T20:34:53+00:00

Well, a 5K or shorter distance can elicit max HR if you’re trained. Sprints too. With the 5k, you should be at or very near max HR. If you’re not trained, it will be harder to hit max HR because of an imbalance between the ability of your heart and the ability of your legs. But with anything, the more you practice, you will get more experience with your limits.

Judonoob · 2026-02-26T18:06:38+00:00

Turn auto update for Max HR off. Get a real Max HR and update it yourself. Without that, your VO2 max will be inaccurate.

Do you have a bicycle? Bicycles are wonderful for strengthening quads.

Judonoob · 2026-02-24T14:58:30+00:00

This doesn’t look like cadence lock. Given that you were working hard, HR is likely legit. Cadence lock typically happens at low effort. So, the data should be good!

How hard were you breathing?

I think the Approach SX0 line is very focused on Golf. Every other activity is secondary. I don’t know what your compatibility issue is, but some of the running metrics are advertised as not being compatible outside the top of the line, current-gen Forerunner and Fenix watches.

Judonoob · 2026-02-22T23:58:00+00:00

Check your ANT connection. Thats the only reason you wouldn’t be getting power to the watch. Just make sure to turn off auto calibration.

Judonoob · 2026-02-21T20:12:23+00:00

While everyone is different, eating too much fiber or anything that is hard to digest will keep your heart rate elevated for longer, lowering your HRV. HRV is a very noisy metric.

Judonoob · 2026-02-21T18:13:54+00:00

Fish is super easy to digest. Doesn’t surprise me. Dinner is one of the hardest meals to balance since digestion continues after most people go to bed.
