Did you Know: Power
Greg Lemond pioneered the use of power meters in the early ’90s, but it is only in recent years that they have become ubiquitous. The pros now race with them – the weight penalty is 20g or so – and if you search a little you can find live and semi-live feeds while the Tour is on, giving speed, power, cadence and heart rate as the guys ride. Google SRM power meters as one option, or look for Velon on Twitter, as they push out summarized power values for certain riders during the Tour. If you have one of your own, or have played on a Wattbike in the gym, make a note of what your five-second, one-minute and five-minute bests are, and then be prepared to weep. The sprinters will pump out 1 500-1 800 watts, after a six-hour stage, in the final metres. Even your toaster will hang its head in shame.
Just have a look at Romain Hardy’s Strava file from Stage 12 – the monster Alpe d’Huez one – where he scraped in inside the time-limit – just – to finish third-last… 3.5w/kg for six hours, just to survive. Gladiators.
