Drivers targeted for Mark Webber Tasmania Challenge

The 2011 edition of the event, which featured former V8 Supercar champion Rick Kelly among the entrants, ended on Sunday, having raised money for the Save the Tassie Devil appeal and the Whitelion youth charity

Red Bull driver Webber, who took part in the first day of competition, was himself a regular competitor in the event - which features cycling, kayaking and trekking - in the past, while fellow grand prix winner Heikki Kovalainen has also taken part.

Webber now wants drivers from Formula 1 and sportscars to compete in the event in the future.

"I would love to (get other motorsport stars to compete), no question about it," he said. "I got a tweet off a couple of Le Mans drivers the other day, so I think for those sorts of guys it's possible," Webber said.

"In terms of Formula 1, the season is getting longer and longer and that's quite challenging for the guys - but if we have any times where the season finishes out this way, then maybe..."

Webber's squad, Team Tasmania, came second in the Elite Van Diemen Cup category last weekend, behind winner Team Iron House.
