Ironbull, Inc. will be bringing Underdown Trail Races to the Underdown. Epic running & biking event on the Underdown and Prairie Dells trails taking part all day with six races (60K, marathon, and half-marathon run and 13, 37, and 111 mile bike) over hills, heavy forest and Ice Age Landscapes making this a thoroughly scenic and challenging race. Since 2021, the run and biking events were combined which saves volunteer resources and costs for the two previously separate events. More details on the website. www.ironbull.org/underdown.details
