So, I have been using a Stryd power meter since late December of 2016, and I really like it. Now, I know that there are people who complain that it is not a direct force PM, meaning that the numbers are not accurate. I am not going to get into that argument; however, I can say that the numbers seem to be consistent for me. Since arriving in the DC area earlier in the month, I have had the opportunity to do some runs along the Mt. Vernon trail. It’s a great trail with a good amount of foliage cover.
That cover, though, messes with my GPS watch and the accuracy of the pace metric. I did a little non-scientific test yesterday evening, and here it is:
I held a fairly constant power output, but my pace changed dramatically when I left the cover of the trees into open area. Same power, but up to 30 seconds/mile of difference on similar grade. You can see that my VI was 1.01, meaning that I had a pretty steady power output range.
Anyway, to me this validates previous experiences I have had with running with power versus pace or HR. If my watch isn’t accurately depicting how fast I am running, then my stress score will be off. Plus, pace doesn’t take into account wind or gradient. You can also see that it was about 90 degrees during my run, which left me with a higher than normal running heart rate for this type of effort. I’m curious to hear about anyone else’s experience running with power. I know @MitchD is now playing with it. Anybody else?
