Tom Bunk set for his 24th Minnesota Voyageur Trail Ultramarathon

Tom Bunk, part of the first-family of ultra running, earned top billing in this preview of the 30th annual Minnestoa Voyageur Trail Ultramarathon in Duluth.

The 69-year-old runner from North Prairie has finished the 50-mile race 23 times, more than any other participant.

"I've been on this course when it's been 90 degrees, when the mud has been up to your ankles and when you've crossed a creek with water up to your waist," Bunk, a retired manager for Waukesha Engines, said this week. "It's a very tough race. You have to be prepared, and even when you are, it's challenging. I have never failed to be humbled by the time I got to the finish line."

Bunk and his wife, Lorraine, are regarded as the president and first lady of ultra running in Southeast Wisconsin. Check out this story from their 50th wedding anniversary, one they celebrated with a 50-kilometer run.
