The OK Hundred trail race invites endurance athletes to challenge themselves amidst the rugged terrain of Eastern Oklahoma's Robbers Cave State Park. This scenic course offers three distances: 40 miles, 100 kilometers, and 100 miles, all following a challenging loop that covers steep, rocky trails with some rock scrambles and stretches along roadways. The race begins at Robbers Cave State Park in Wilburton, Oklahoma, where participants will experience an elevation gain of approximately 2549 feet per lap. The event is scheduled for the weekend starting on Friday evening through Sunday afternoon, providing ample time for runners to acclimate before their respective start times. Early packet pickup is available at the park from 2-5 PM on Friday and again in the morning hours leading up to race day. Runners should prepare to carry their own hydration systems as no cups are provided along the course. Pacers are permitted only after completing two laps for those competing in either the 100K or 100-mile events, adding an extra layer of strategy and planning to the challenge. The event is known for its scenic beauty and supportive atmosphere, with fully marked trails ensuring clear navigation throughout the race day. Aid stations along the route provide essential hydration and nutrition to help runners maintain their energy levels over the grueling distances. Photography at key points around the course captures memorable moments from each participant's journey through this challenging landscape. Upon crossing the finish line, all participants receive a long-sleeve event shirt and a finisher medal, while top male and female competitors in each distance earn additional awards. Distinctive silver buckles are awarded to those who complete both 100K and 100-mile races within their designated cutoff times. For runners looking ahead to future challenges, the Outlaw Membership offers significant value with race credits applicable across multiple events throughout the year. This membership includes exclusive perks such as priority access for select races and discounts on entry fees, making it an attractive option for frequent competitors.
