Interestingly enough it didn't seem to help a bit in actual race circumstances, or even to close out a typical road race. Specificity is an interesting thing.
This was when he was a Sky domestique, which he did well. Specificity indeed.
that's an interesting insight TP that i was completely unaware of. in fact i had been getting disgruntled about the lack of movement in my 1 min, 5 min etc. but at the same time i had been riding at levels of power output for durations of time that i found pleasantly surprising.
A few years ago I started looked at the ratio of what power I could hold for 30, 45, 60 and 120 minutes compared to my peak 20 power. Sure enough, the longer I've ridden and raced for the more that gap has narrowed. All this before hearing those anecdotes from the pros.
My 'issue' now is I cannot seem to push through my FTP ceiling much more.
