Cycling - WorldTour begins Down Under

The 2013 UCI WorldTour begins in Australia on Tuesday with the sport firmly under a cloud following Lance Armstrong's doping revelations.

The 15th edition of the Tour Down Under is the first of 29 races - 15 stage races and 14 one-day events - on the calendar.

Each stage of the six-day race is held near Adelaide with world champion Philippe Gilbert (BMC), Andre Greipel (Lotto Belisol), Edvald Boasson Hagen (Sky), Tyler Farrar (Garmin-Sharp), Matt Goss of local favourites Orica-GreenEDGE, Marcel Kittel of WorldTour newcomers Argos-Shimano and Mark Renshaw of Blanco Pro Cycling - the successor of the former Rabobank team - looking to contest stage victories in bunch sprint finishes.

But in at least three of the six stages there is a considerable amount of climbing to do and the likes of 2010 Tour de France champion Andy Schleck (RadioShack Leopard Trek) will look to challenge defending champion Simon Gerrans (Orica-GreenEdge) for the ochre jersey.

Gerrans was the eighth Australian winner of the race and the short but testing climb of Old Willunga Hill is expected to decide who goes on to win this year's race.

Greipel, the winner on GC in 2008 and 2010, won Sunday's criterium warm-up and believes the race will be a good early test.

He said: “The stages look very feisty. I expect that in three of the six stages there will be an opportunity for the sprinters. For the other stages we can rely on a guy like Tim Wellens.

"Apart from Cavendish, Petacchi and Sagan the most important sprinters are present, so it will be a first moment to see where we stand.”
