Thunderbird Warrior Challenge 2026

The second annual Thunderbird Warrior Challenge in Bayfield is Wisconsin’s northernmost trail run and the only run with views of the Apostle Islands. The event features 50k, 25k and 10k trail run options and a 5k run with obstacles. There are also games, entertainment and activities throughout the day.

The run courses feature a mix of rolling trails, technical singletrack and panoramic vistas of Lake Superior and the Apostle Islands. Runners explore diverse terrains, including old-growth maple stands and sandy pine forests, with challenging climbs and descents through glacial topography. Notable highlights include passing the historic Nourse Sugarbush State Natural Area and taking in views from Mt. Ashwabay.

The challenge kicks off at 6 a.m. with the 50k trail run, followed by the 25k and 10k races at 8 a.m., and a 5K fun run and obstacle course at 9 a.m.

This event is also a chance to honor veterans and first responders, with discounts for those groups and free entry for active-duty military personnel.

All proceeds from the event benefit Camp Benesi and Mt. Ashwabay Outdoor Recreation Area.

Camp Benesi is a nonprofit recreational getaway for veterans and Gold Star families who are grieving loss or dealing with the effects of military service. Created in honor of MSGT. Jonathan J. Dunbar, who was killed in action in 2018, Camp Benesi’s mission is to provide a safe and peaceful retreat for its guests to enjoy a variety of outdoor activities and connect with others who share similar experiences. It offers free lodging, meals and activities at no cost to its guests.

Mt. Ashwabay is a nonprofit ski and recreation area dedicated to promoting outdoor activities and community engagement throughout the greater Chequamegon Bay area.

On-site (primitive) camping is available for those looking to immerse themselves in the event and the beautiful natural surroundings.
