The Kenyan-born all-rounder is the bookies' favourite to win the 2013 Tour, even more so after the withdrawal of his Sky team-mate – and 2012 winner – Bradley Wiggins.
There had been question marks over which of the two Brits Sky would get behind this year, but with such a mountainous route lying ahead, Froome always looked like getting the nod, and he will now lead Sky into the 100th Tour.
Froome's rare combination of slender physique, raw power and immense stamina make him almost the perfect Grand Tour rider, but it remains to be seen if his personality is forceful enough to keep his team-mates on his side at all times throughout the Tour.
There can be few doubts about his form in 2013 – Froome has already picked up the Tour of Oman, the Criterium International and the Tour de Romandie.
