Event Overview

The Iron Will 100 takes place in Junction City, Kansas, organized by Iron Will Racing. The event features several endurance distances held on a course located at 5203 N HWY 57. The route utilizes a river trail that is flat and provides approximately 75% shade for participants.

The available distances include:

The course is structured as an out and back loop on a fast river trail. For the 100 Miler, participants complete the out and back ten times. The 50 Mile consists of five out and backs. The 50K includes one short out and back followed by three longer segments to reach the 31 mile total. Manned aid stations are positioned every 5 miles along the route to support athletes.
