MARCH athlete Sean Brown has been forced to retire from the Yukon Arctic Ultra, the world's toughest race.

He took a wrong turn in the Canadian wilderness and strayed from the course for four hours.

An exhausted Brown, 36, was safe and well and resting at the Braeburn checkpoint, 100 miles into the brutal 320-mile race. He decided to withdraw because he felt unable to complete the course before the eight-day deadline.

Injury forced Brown to withdraw from his first attempt at the race last year and although he was obviously disappointed he was reported to be in good spirits and joked that the wrong turn had given him a chance to see more wildlife.

The race is led by American Andrew Matulonis, who is setting a blistering pace, ahead of Canadian Bruce Thompson, Scotland's Hugh Hunter and England's Stuart Gillett.
