A former March AC runner has completed a treacherous 430 mile race across Canada ... at the fourth attempt.

Sean Brown, who is from March but moved to Colorado four years ago, braced temperatures as low as -50C as he ploughed his way to the finish line in the Yukon Arctic Ultra 2015.

Organiser Robert Pollhammer said: “Sean crossing the finish line was for myself and I’m sure the entire crew a moment we will not forget.

“This was Sean’s fourth try at the 430 miles. Of course we all admire people who come here and finish on the first try. But to have Sean come back again and again and finally achieving it is simply amazing.

“Sean is a true hero of the Yukon Arctic Ultra.”
