Webber was attended by paramedics at the scene before being airlifted by helicopter to the Royal Hobart Hospital, where he underwent surgery to insert a pin in his right leg. He is expected to stay in hospital for around three days before beginning a rehabilitation programme.
The Australian was participating in the penultimate day of the 2008 Mark Webber Pure Tasmania Challenge, a 250-kilometre endurance event that involves teams of sportsmen and women competing using mountain bikes, kayaks and trekking.
"Mark's in good spirits," the event's director, Geoff Donohue, was quoted as saying by the BBC. "The broken leg is the injury, and beyond that, he's in really good shape. He has a little bit of a graze on his left forearm, but he has had full scans and everything else is clear.”
The accident will almost certainly rule Webber out of any Formula One testing activity with Red Bull until the New Year.
