Iron Will Backroads

Iron Will Backroads is an ultramarathon event held in Enterprise, Kansas, featuring 50K, 100K, and 100-mile race distances. The course consists of 7.7-mile loops on a mix of gravel and asphalt roads, with runners completing multiple loops depending on their chosen distance—four loops for 50K, eight for 100K, and thirteen for 100 miles. A fully stocked aid station is located at the start and end of each loop, offering typical and hot foods, with an additional unmanned water stop if temperatures exceed 80°F.

The event provides finisher buckles, awards for top male and female runners, and allows pacers from the sixth loop onward. Visit the organization's website for the most recent information.
