Chris Froome to win Tour de France by 133 seconds (30th June 2017)

The 104th Tour de France will be decided by 133 seconds, according to leading spread betting firm Sporting Index.

Six of the last seven Tour winners have streaked clear by three minutes or more, but this year looks set to be a closely run race with Sporting Index quoting a winning margin of just 133 seconds.

Despite a disappointing fourth place in the tournament's traditional Tour warm-up, the Critérium du Dauphiné, Chris Froome is predicted to get the better of Colombian rival Nairo Quintana in cycling's most famous race this year.

However, it's Richie Porte who is the Team Sky rider's closest competitor this year, with the Australian laying down an early marker for the Tour de France when he finished ahead of Froome in the Critérium du Dauphiné earlier this month.

Four different riders are predicted to wear the `maillot jaune' before the 21st and final stage finishes on the Champs-Elysees in Paris.

The Manx Missile, Mark Cavendish, looks unlikely to add more than one stage success to his 30 career victories this year as he continues his quest to surpass Eddy Merckx's record of 34 Tour de France stage wins.

Sporting Index expect just 165 of the 198 riders that start stage one to finish the race.

Ed Fulton, trading spokesman for Sporting Index,said: "Chris Froome faces an uphill battle if he is to win a third consecutive Tour de France title this year, with Richie Porte a serious challenge to Froome's crown on a course that is expected to suit the Australian. We think this could be a highly competitive Tour and predict a winning margin of 133 seconds."

"Froome's preparation has been far from ideal, entering the Tour without having won a race this year for the first time since 2012. With the margin of victory set to be a slim 133 seconds, the Team Sky rider knows he faces his stiffest competition yet with the likes of Porte and Quintana nipping at his heels."
