Sure, you can train on rollers and a trainer and get some idea of performance improvement or regression, but how does one get info on the road
yes you still have to do the work but how are you measuring that
You see, this is why I don't see the point.
You are asking 'How on earth can we measure our improvements without a Powermeter?'
Um, well, given that you are training for competition, surely the way to measure improvement is in better results; better times in TTs, better results in RRs? You know, like all those racers who have gone before you, like all those racers who don't use PMs..
It's as if the training tool, the PM, takes on a significance way beyond it's original function, and the things ascribed to it are nothing short of wonderful; it's a tool, just a way of measuring stuff, not anything other than that.
As Sonomasnap eloquently reveals above; he sat in for a race then fluffed the sprint; he doesn't need a PM, he needs to learn to sprint.
As I said, I'm not against them, I just don't see the need, they produce another set of numbers to geek over, but you still have to do the work.
...and cycling competition is about so much more than watts per kilo.
Anyway, I appreciate I've pulled the thread off topic, and I'm not making any great contribution..
