This was supposed to be the last true high-intensity bike ride in the build period. If you go by how I felt, I'd agree with that assessment, but if you go by the numbers, it's just not there. I don't know what's going on, and it's getting harder to not be concerned. For the second week in a row, an effort that should be tough but doable has pretty much wrecked me, and I don't know why. I feel fine on the commuter, and move at my usual speed, but on the trainer, I'm not turning out the power I should be able to do. I know the wheel isn't rubbing, the brake isn't applied, and I'm calibrating every ride, but I continue to lose power. There isn't any time to worry about it, though, so I'll get through the week, then rest my ass off during the taper and hope that the problem is with the i-Magic and not with my legs. Fingers crossed.
Bike: 65 minutes, w/2x20 minutes @ 240-280w, 5 minutes recovery
Run: 2 miles @ 7.8 mph + 4 strides
I would put money on this: and hope that the problem is with the i-Magic .
ReplyDeleteRecall my experience using the i-Magic and my Powertap. Not only did the absolute numbers disagree, but the delta between the i-Magic and the PT wasn't fixed... the only function that seemed to accurately map i-Magic numbers on to PT numbers was one-off stochastic noise with occasional trends.
I seriously wouldn't put any stock into i-Magic numbers... especially if you're feeling good everywhere else.
I agree, I just find it odd that after 18 months of, at least, "the numbers are higher when the effort is harder", it's suddenly so fat out of whack. But I can't do anything about it now, so I'll get my last few rides in, and see what's what in Florida.
