The Iron Will 100-Mile Ultra was inspired by a runner's resilience through adversity, especially after facing personal challenges. It features a flat, fast, and smooth trail that winds along a river, offering about 75% shade, making it an ideal course for personal records. Runners can expect well-stocked aid stations every 5 miles to support their journey, with additional provisions if the heat rises above a set temperature. Aside from the 100-mile option, participants can also choose 50 miles or 50k, each consisting of multiple out-and-back sections. The course is designed to be inclusive and accessible, even allowing strollers for those who need balance assistance. This race welcomes runners of all levels, creating an inviting atmosphere for all to challenge themselves.
