Merckx index said:I guess it depends on where you start:
If the climb is 840m at 7%, then Froome's power is estimated at a much more believable 6.16 watts/kg. Anyone know where he started?
It's interesting that TD is so high on that list, the same as Porte, and only a handful of seconds behind Froome. He's a known doper, like the others below him on that list, but would any of these guys actually dope for a one shot climb that isn't part of a race, for a training ride? You might a little, but you obviously wouldn't waste a blood bag on a training ride. So maybe those times are for a shorter distance. But if Froome is going to compare his time to those of others, he has to know where everyone started. So if he knows what he's talking about, there must be an established place where all the pros start.
Then again, in the same article quoted above, it says Ferrari expected LA to do the ride in 6.8 watts/kg. He surely couldn't have done that clean. And his stated time for 12 km wouldn't do it. Some things don't add up.
Madone does not have official starting point. It can be 15 km long and 9 km long and anything between. I checked Starva (several pros have Madone segments in Strava), but problem is same: no established starting point, lenght of the climb can vary a lot, different segments have listed as Madone.
