If last year’s Tour de France often resembled a triumphant Chris Froome march to Paris, the road to the Champs Elysees may be more unpredictable this time especially with Alberto Contador likely to be back in the hunt.

Chris Froome

Chris Froome took control in the eighth stage in 2013 before trouncing his rivals in the mountains and the time trials as Alberto Contador struggled to find the form that helped him win the race in 2007 and 2009.

Although the Briton should receive unprecedented support as the Tour starts in Leeds today – the second Grand Depart from Britain in eight years – that will count for little when the event enters France.

Froome will rely on backing from a strong team that includes Geraint Thomas and Bernhard Eisel although the Sky outfit have decided to leave out 2012 champion Bradley Wiggins.

The defending champion has not had a brilliant season, however, and his lieutenant Richie Porte has also struggled.

In addition Team Sky recently faced off-road, doping-related allegations that the UCI has yet to clear.

Froome won four stage races in 2013 but this season he has only triumphed in the Tour of Oman and Tour de Romandie and crashed in the last warm-up event, the Criterium du Dauphine, before finishing 12th.

It will be a treacherous 2014 Tour for him as it features stretches of cobbled roads, a tricky crossing of the Vosges mountains and only one time trial.

Contador, who was stripped of his 2010 Tour title after testing positive for a miniscule amount of the banned anabolic agent clenbuterol, must do without key team-mate Roman Kreuziger.

The Czech rider, fifth in last year’s Tour, is out of the Tinkoff-Saxo team because he faces a possible UCI investigation into his biological passport data from 2011 and 2012.

Extra motivation

Contador, though, seems to be in the form of his life, having beaten Froome in the Dauphine to finish second overall and also winning the Tour of the Basque country and Tirreno-Adriatico.

“Last year he dominated the Tour and there was nothing we could do about it,” Contador said.

“It was a strange feeling being on the podium as winners of the team classification. It’s one of the things that motivated me to improve.”

The fight between the top guns could start before the usual battlefields of the Alps and the Pyrenees as the 10th stage takes the peloton to La Planche des Belles Filles – where Froome took his maiden Tour win in 2012 – with four category-one climbs on the menu.

This is where the outsiders may try to blow the race wide open.

It will be at this stage that the credentials of Italian Vincenzo Nibali, Dutchman Bauke Mollema, Belgian Juergen van den Broeck, Spain’s Alejandro Valverde and American pair Andrew Talansky and Tejay van Garderen will be tested.

Spain’s Joaquim Rodriguez, third last year, targets only stage wins but should he be well placed after the Alps, the Katusha rider could amend his targets.

The absence of last year’s runner-up, Colombian Nairo Quintana, takes some of the drama off a race that otherwise promises more thrills than last year.

France, who have been waiting for a home Tour winner since Bernard Hinault in 1985, will follow Thibaut Pinot and Romain Bardet although a top-five finish would be quite an achievement for both.
