We have 2 kids and a third is on the way. Very little chance for any consistency other than on the bike...
I was monitoring power while trying to keep up with Di Luca up Mt Zoncolan. Sweet spot is such a narrow band that it is really hard to keep in it, even on an indoor trainer.
I was pretty chuffed not to say surprised that the two were so close, as my power reading goes up and down like a yoyo, but since the window is only 14 watts there's got to be a close eye kept on the PT.
Off topic, but I watched a sprint stage on this year's Giro, it was the first or second flat stage after Zoncolan. Two AG2R guys led into the final bend before the line and the lead guy's front wheel just went from under him, he was going that fast. Impressive crunch into the barriers!
