Only in International Falls does a 47-below-zero windchill day merit a steady stream of "likes" on Facebook.
Ken Krueger likes it, too.
Krueger and his wife, Jackie, are race directors of the Arrowhead 135 Ultramarathon, an endurance race that pivots on a paradox: The region's otherworldly cold makes the race what it is, yet that same extreme can mean its participants' undoing.
No matter. Another Arrowhead begins at 7 a.m. Monday in this frozen stretch of northern Minnesota, where more than 160 hardcore racers will set out into the wild along the Arrowhead State Trail and toward fates uncertain. By bike, by ski or by foot, their destination is Tower — or bust.
History shows fewer than half the competitors will finish, Krueger said. Last year, when the windchill at times bit into racers with minus-50 degrees, about 35 percent of the 141 who started made it to the finish at the Fortune Bay Casino. The first, by wheel, rolled in after 20-plus hours; the first runner, just over 43; the lone finisher by ski, 54.
Krueger can relate to the extremes and his flock: He has raced Arrowhead seven times since 2007, and by all three means. Early this month, he talked about the race, its informal beginnings and its robust, global following:
On his initiation to the Arrowhead 135: "I live in International Falls. There was just a little, little thing in the paper, 'Hey, they are having this race.' They had a racers' dinner, and there were 10 racers that first year [2005]. There were just the 10 racers and just a couple of family members and me. It's like, 'These people are really cool. I want to try this.' … The first chance I got was 2007, and that was the year it was the lowest finish rate ever. And that year I was the last biker in — I was the ninth finisher on bike, and there were only nine finishers on bike and one on foot."
On the race's evolution: "I think the difference is the applicants just keep getting better and better. The equipment gets better. People are better about sharing information, better prepared … Facebook, Internet, all that stuff. People share tips and ideas, and we have literally — to International Falls — people coming from all around the world. Just some elite-type people, so it's just really neat for the race.
