Park Tool engineer directs Arrowhead Ultra Marathon

Pierre Ostor, Park Tool's lead engineer will take a break from designing bicycle tools to direct the second annual Arrowhead Ultra Marathon. The 135-mile event begins on February 6 in International Falls, MN and ends 30 to 60 hours later at the Bay View Lodge on Lake Vermillion.

The course follows a hilly State multi-purpose Trail under extreme winter conditions. International Falls is often the coldest place in the USA with February temperatures as low as 60°F below zero. The contestants can bike, ski or run the race on foot and must be self-sufficient, carrying their own food, water, and accommodations. Last year's winner, Matthew Evingson completed the course in 28 hours and 54 minutes. Thirty-one hearty souls have already signed up to compete in this year's race.
