Hey Trail Runners! This sounds like a great event. It's the first annual tBunk Endurance Challenge, in honor of ultra runner Tom Bunk. It's run on the ski trails at the Nordic trail head (Home of the Ice Age 50). Plenty of distances to choose from: 200 miles, 150 miles, 100 miles, 50 miles, 50k, or shorter. It sounds like the atmosphere may be similar to that of the John Dick, which is pretty much amazing. Runners are welcome to do as many loops as they choose, from 9-200 miles! Plus, a portion of the entry fee will be donated to charity.
