Does anyone know why run speed from Zwift doesn’t look the same in Strava? Run speed during my zwift runs match what my bluetooth enabled treadmill says (there’s actually a few seconds per mile difference but it’s consistent - doesn’t jump around if I don’t change the pace - I haven’t done the math to see which is correct at a given mph). Looking at the run after on zwift website shows flat lines for pace when the pace stays the same, and it moves appropriately if I adjusted the pace during my run. So far, treadmill display, zwift stats in-app during the run, and zwift website all appear to be consistent.
When I look at a zwift exported run on Strava App sometimes the pace graph shows momentary spikes even though I knew I was going a constance pace at that time. The Strava website pace graph shows even more fluctuations. Usually 1-2 seconds per mile but sometimes as much as 10 seconds per mile difference. Those bigger spikes correspond to the spikes on the app. The fluctuations aren’t uniform.
I have a Sole treadmill - is it sending belt speed to zwift? I assume not because when I start a run it takes a few seconds to get up to speed but in the game speed changes look to be instantaneous and I don’t see the slow ramp up in the zwift or Strava data. Or is zwift sending something else to strava that’s different from it’s own website? It doesn’t seem to make a difference, Overall pace seems to be within a second per mile each run.
Just strikes me as weird. Does anyone know what’s going on?
