Froome undergoes testing to quiet doubters

Sky's Chris Froome undergoes physiological testing in London on Monday, in part to quell doubts about his Tour de France performances.

Don't miss a moment from Paris-Roubaix and Unbound Gravel, to the Giro d’Italia, Tour de France, Vuelta a España, and everything in between when you join Outside+.

Chris Froome (Sky) underwent physiological testing Monday in a bid to quiet those who doubt his performances at the Tour de France.

Froome, 30, caught flak in July en route to his second yellow jersey. Some questioned the legitimacy of his performances. To counter doubts about his ability to hit power numbers, he promised to test himself in lab conditions to demonstrate his physical boundaries.

In messages posted on his Twitter account Monday, Froome promised to release the information later this year.

It was not clear exactly what testing was completed, but it could reveal such parameters as Froome’s VO2 max and his maximum heart-rate, with hopes that the information could quell the storm that inevitably seems to kick up every time Froome takes the yellow jersey.

“Chris Froome has started the program of physiological tests he promised he would undertake during the Tour,” a Sky spokesman said. “The process will continue later in the year and Chris has given a commitment that the results will be made public. This process is part of Chris’ and Team Sky’s ongoing desire for greater public transparency to help to continue to build trust in the sport.”

The GSK Human Performance Lab in London hosted the training sessions. Froome also posted a short video clip on Twitter, and the lab posted a message, “Great to have Tour de France winner Chris Froome in today, working with the HPL team to measure and improve performance.”

Froome has been busy since winning the Tour. Not only has he participated in nine, post-Tour criteriums, when top riders can earn up to $50,000 in appearance fees, he’s also been undergoing intense time trial training sessions with Sky coach Tim Kerrison, suggesting that he already has his eye set on his top goals for 2016. Froome stated his main objectives for next season will be defending his Tour title in July, and then trying to strike gold in the individual time trial in the 2016 Rio de Janeiro Olympic Games in August. He won bronze in London 2012 behind former teammate Bradley Wiggins. Monday’s tests also served to replicate conditions of what he expects to face in Rio next summer, according to Froome’s Twitter.

Also on Monday, Sky confirmed its lineup for the Vuelta a España, with Ian Boswell tapped to make his grand tour debut in support of Froome.

Froome will be trying to become the first rider to win the Tour and Vuelta in succession. Jacques Anquetil (1963) and Bernard Hinault (1978) won the Vuelta and Tour in the same season, but achieved the rare double when the Spanish grand tour was held in April. No one’s matched the feat since the race moved to September in 1995.
