We wanted the tBunk Endurance Challenge to reflect the personality of the runner it’s named for. So this event is tough but fair. There is plenty of elevation change (1,500 feet per loop) and the weather in Wisconsin at the beginning of November will likely test your ability to deal with temperature extremes. But, unlike some long distance events, ours is designed to test your mettle not your patience. No matter what the weather, these trails will remain runnable. So if you’ve ever thought about challenging a new distance, or setting a PR at one you’ve already conquered, this is the event for you.

All the events will be run primarily on the Nordic Blue loop. The loop is 9.19 miles in length and will include an unmanned aid station at the half way point and a manned aid station at the start/finish. See website for complete info.
