Jeremy Ross's explosive pace in the final run over the Hazards Mountains into Wineglass Bay saw him blast past his rivals in the Freycinet Lodge Challenge yesterday, taking out the Australian Multi-sport Champion title.

Ross, 32, of Canberra, won the open male individual title after a tight battle with veteran Launceston competitor John Gregory on Saturday, and Victorian Jarad Kohlar yesterday.

It was Ross's first crack at the title after hearing about the race from good friend Jody Zerbst, who won the Challenge last year.

"This leaves anything for dead that I've done in Australia and I'll go back and promote this race - it's just fantastic," Ross, and Australian army captain, said. "I gave myself 30 weeks to train for it and didn't miss a beat."

Ross and Kohlar were neck-and-neck after the kayak and road cycle yesterday, although on overall time Kohlar was struggling to make up a 11-minute deficit he suffered on Saturday due to a tyre puncture.

Ross was three minutes ahead of Kohlar after the 22km mountain bike, but it was the 15km up to Wineglass Bay lookout and down onto the beach and back where Ross pulled away.

Kohlar made up some of his lost time to run in second yesterday, almost four minutes ahead of Hobart's Sean Clauson in third. Gregory slipped back in the rankings today, but still took out the veteran individual male title.

Hobart's Imojen Pearce won the women's individual title. After fighting off a strong challenge from world orienteering champion Hanny Alston on Saturday, Imojen led the way out of this morning's kayak leg and was never headed.

Race organisers battled blustery winds for both days of the race, with the kayak from Dolphin Sands to Swanwick cancelled on Saturday, and the opening kayak yesterday transferred from Freycinet Lodge to Swanwick due to unsafe weather conditions.
