One of the best features of WKO+ is the "fast find" feature. In the ride graph you can search your effort for a self-specified power range. Besides the food poisoning last Saturday night I was surprised to get dropped on the Sunday ride. I was curious since I had done 5x5 VO2 max and 6x3 VO2 max efforts the Tuesday and Thursday before the ride, whether I had over extended in that range and was just very tired when those efforts came up in the fast ride.
What I found going back is that I had burned 13 matches of efforts between 30 to 2 minutes where the power average ranged between 318w and 450w.
Also, in looking at the power distribution graph I was 13 minutes total in VO2 max and 16 minutes above that.
While the ride might normally be in my wheelhouse, I would suspect that if I were to do a ride like this later in the week it might be better to adjust my intervals earlier so I can put in a better performance.
