For the last few Zwift rides I’m finding that after 4 or 5 ks my speed isn’t matching up with my watts. I’m hitting 250-300 w up a Zwift incline that I’ve done many times before ,knowing I should be sitting mid 20k’s, and Zwift has me going 8-9 kph ! As mentioned it only started a few weeks ago.
I also notice no resistance from my trainer ( wahoo kickr early vs 1). I stop and save the ride, re calibrate again , and it normally takes 2 - 3 rides of 4-5 ks ( stopping,saving and re starting again ) till it comes good.
Any ideas ?
