The estimate for Froome ranges between 6.1 W/kg (Ferrari method) and 6.2 W/kg (CPL method) for the 41 min climb.
For the sake of comparison, the estimates compare favorably to estimates of Robert Gesink’s power output. As per his MEASURED power output reported on Strava, he produced 409 W (5.8 W/kg if we go with 71kg, halfway between his Strava-listed and team-website listed mass), while the CPL method estimates 408.8W (5.8 W/kg) and Ferrari’s formula 5.86 W/kg. Conservatively then, I’m once again confident that the estimate for Froome is not outrageously wrong (I’d say it’s exceptionally accurate), and that he was at least at 6.1W/kg (calculations & times, as always, provided by the excellent Ammattipyoraily)
Quintana, incidentally, at 5.9W/kg, was just slightly above what we’ve seen from the Tour winners for the last four years, for the length of the climb, while everyone else was down on estimates, so a howling tail-wind won’t cut it this time.
For 41 minutes, making some conservative assumptions (that is, weighted in favour the rider), that implies a VO2max over 90 ml/kg/min, but more likely mid-90s, because he’d need to be riding at a super high % of max for it to be any lower. Or he must be 25 to 26% efficient, something documented and disputed only once before. And of course, the combination of super high VO2max and high efficiency is, by definition, rare. Too many ifs and buts, however, so moving along…
i 6.1 W/kg za 40 + min je previše.
