The third annual Badger Mountain Challenge is planned March 29-30. It includes three events: a 15K trail hike or run, a 50K ultra-marathon and a 100-mile endurance run -- each one starting and ending in Badger Mountain's Trailhead Park.

Cost is $20 for the 15K, $40 for the 50K and $125 for the 100-miler if registered by Thursday. After Thursday, the price increases. Shirts cost an extra $18.
