Wrist Running Power

@Egika lack of wind in calculation is a bummer. Also - changing of effort due to ground surface change.

The wind adds or detracts very little to power unless the wind is very strong and would affect HR as well. This is true from Stryd’s pod. I am not sure wind is worth it. Instantaneous power IMHO is not very useful, but the zones definitely are. Changes in your direction vs. wind would have to be near instantaneous.

@Brad_Olwin well, this is the case. I’m not thinking about a lil windy, but mouthful of wind. I usually run through the fields, and there are hardly any trees, and it’s flat as a pancake. I can easily go +/- 20 HR if I’m with or against the wind. But the power stays the same. Just curious - would Stryd pick it up?

In my experience wind added more noise and inconsistency during runnings when is a wind from one side… I’m not a huge fan of wind stride pod for that reason and the valued added is not so important.

Yes wind exists and it is there but I don’t find it useful.

I think that we need new sensor for wind.

@suzzlo interesting, do you have any insights how it compares to wrist based power?

I have done a lot of testing with 9PeakPro with the Stryd Pod (generation prior to wind). They are very similar. The major differences I saw were on very hard VO2 Max intervals the Stryd had higher max power and slightly higher avg power. Not enough to change the Critical Power calculations. Wrist-based power is much more convenient and always there. I did not like having to deal with the pod all the time.

WOW, s9peak has wrist power. I see I see.

Yesterday had a very windy first part of my easy run, this was well captured by my Stryd pod, as you can see 6% of my total power output was added by wind resistance

I’d say if you’re just getting started with running power and don’t have a Stryd pod, the wrist based power is a good start

@zhang965 Sorry about that, they look the same and I can forget which one I have on my wrist. Thanks for the correction. I fixed the post.
