Temperatures are expected to plummet again over the weekend and into next week, but that won't stop racers in the Annual Arrowhead 135.
The race kicks off Monday morning in International Falls, where temperatures could be 30 below with a wind chill of around 55 below. Bikers, walkers, runners, and skiers have 60 hours to complete the 135-mile course along the Arrowhead State Trail. Only about half of the participants usually complete the grueling race. Mike Lessard, who is participating this year for the fourth time, spoke with MPR News' Tom Crann about the race.
