Will Davison and Mark Winterbottom both shrugged off debilitating foot injuries to produce a Ford one-two in the V8 Tasmania Challenge.

Davison clinched his second race win in succession after his success at the Clipsol 500 in Adelaide and stretched his series lead, despite fighting a mystery foot problem.

And Winterbottom, who qualified on pole position, allowed himself to be jumped by Davison at the start as he fought against an ankle weakened during a water skiing accident.

The pair led throughout the race and continued Ford’s early dominance of the championship although defending champion Jamie Whincup managed third to keep Holden’s points tally on track.

Davison scored by just half a second from Winterbottom with Whincup a further nine seconds back.

Davison said he had been given no proper diagnosis of his recurring right foot issue which flared again on Saturday.

“I’ve worked on trying to get on top of it and we’ve improved the situation, no doubt,” Davison said.

“We got through the Clipsol with no problems but it put its ugly head up in that race.

“The last 20 laps today was a nightmare to be honest, just trying to focus on not making a mistake.

“It happened here last year when I ran wide with three laps to go…I was just thinking back to that moment and thinking, don’t make a mistake again.”

Davison said he was undergoing various forms of treatment but nothing had produced a cure.

“I just get complete numbness in my foot so it’s obviously just cutting off the circulation somewhere.

“When you go 50 or 60 laps without a safety car it’s never easy.

“It could be back, sciatic nerve – there’s a million things I’ve been looking at and treating.

“Before I get in the car I’m getting acupuncture in my butt cheek…all sorts of stuff,” he said.

Winterbottom said he was confident his ankle strength would return but it continued to hinder his starts.

“Maybe I’ve lost my reflexes but I just can’t modulate (the clutch) off the line,” Winterbottom said.

“I’m just wheel-spinning all the time when I used to modulate the clutch quite a bit.

“Once you get going it’s fine, but it’s just the starts (because) it’s very important around a track like this to get a good start.

“I lost two positions so it is costing but it will only get better,” he said.

Davison said he intended to work hard to put a lid on his emotions after his victories in Adelaide and Launceston.

“I’ve just got to try to enjoy the races and rack up as many wins as I can – to get another one so early feels really good inside,” Davison said.

“I’ve just got to concentrate on staying calm now. I got a bit excited by the Clipsol (Adelaide) thing but now it’s going to be a long, hard road this season.”

Davison now holds 438 points from Whincup on 399 and Winterbottom with 360.
