Lace up your shoes for the Badger Challenge on Sunday, September 27, 2026, in Madison, Wisconsin, a signature event that combines an exhilarating race day with a powerful mission to advance cancer research and patient treatment at the University of Wisconsin-Madison and the UW Carbone Cancer Center. Runners can choose between a challenging 13.1-mile half marathon or a spirited 5K run or walk, knowing that every stride directly supports a vital cause, with 100% of participant-raised funds dedicated to increasing cure rates and reducing the burden of cancer for future generations.

The half marathon course features a rolling terrain with approximately 420 feet of elevation gain, offering a satisfying challenge for running enthusiasts, while the 5K run presents a more accessible route with around 145 feet of elevation gain. Both courses are primarily on roads, likely offering scenic views of the Wisconsin landscape, similar to the event's well-regarded bike routes that wind through picturesque countryside and past rolling fields. Runners will be well-supported with aid stations approximately every mile for the half marathon and two for the 5K, providing essentials like water, Gatorade, Honey Stinger Waffles, gels, and bananas, alongside crucial medical assistance and bathrooms. Typical race day conditions in late September offer ideal running weather, with highs around 68F and lows around 48F, and a minimal 14% chance of precipitation.

The Badger Challenge cultivates a fantastic race day atmosphere, starting and finishing at the UW Health Eastpark Medical Center, with the 5K events also converging there for a vibrant post-event celebration. Participants receive a commemorative finisher medal and a participant shirt, along with complimentary professional on-course photos to capture their achievements. The festivities continue with a post-event meal and a dedicated Kids Zone, making it a memorable experience for the entire family and a truly impactful event for the community.
