Iron Will Backroads

Iron Will Backroads takes place in Enterprise, Kansas. The event offers three distances—50K, 100K, and 100 mile—run on 7.7-mile loops composed of gravel and asphalt. The 100 mile option requires 13 loops, 100K eight loops, and 50K four loops.

Each loop has a full aid station at the start/end with standard items and hot foods; if temperatures exceed 80°F, an unmanned water stop is added about five miles into the loop. Pacers are allowed starting Loop 6 (one at a time) with waivers. All finishers earn buckles; awards for male and female winners; and every participant receives a tri-blend shirt.

Shirt deadline: May 1; registration closes May 13; 30-day deferrals available. Visit the organization's website for the most recent information.
