Iron Will Grand Slam
The Iron Will Grand Slam is a series of four 100 mile races based in Enterprise, KS, with a listed venue at 619 S Lincoln. The series combines four separate hundred mile events held across the year and awards finishers from each race.
The four events in the series are Earth Day Buckle Mania (April 24), Iron Will Backroads (May 16), Honey Badger Road Race (July 11), and Iron Will (September 19). Entry for the combined series is offered as a single package covering all four races.
The published entry fee for all four races is $750. Registration closes on Wed, Apr 22 at 11:59 PM CT. Because the package is offered at a discounted rate, refunds or deferrals are not available.
Each race awards a unique finisher buckle. Grand Slam finishers receive a 15 inch by 12 inch custom plaque that lists their name and finishing times. Visit the organization's website for the most recent information.
