Well not long finished my first ride with a power meter (
https://www.strava.com/activities/834927926).
I know it's a bit early to make sense of it, as I have nothing to compare it to, but it was still really useful to see how I coped over such a long ride. For example, 175-200W seemed to be my sweet spot for an average pace, but I really faded near the end (didn't eat enough), and it was interesting to see how I could barely stick to the same power (in fact I could barely reach triple figures at times lol!)
I can see how it will be a really useful pacing tool too, as it was useful to see my power on longer climbs, and trying to stick to a comfortable level.
I'm mainly using 3 second smoothing, I was surprised at how much this jumps around, let alone the normal instant power reading!
Really pleased so far, and I guess it's one of those tools where the more you ride, the more useful it'll be.
Bring on another ride tomorrow! My legs are feeling it too, so no FTP test for the moment lol!
