Nestled within the scenic Rock Bridge State Park in Missouri lies an exhilarating trail running experience that challenges even the most seasoned ultrarunners. The annual Rock Bridge 2.0 race offers two distances: a grueling 50K and a more manageable yet still demanding 25K, both winding through diverse terrain and showcasing some of the park's best trails. ### Course Overview The event kicks off at Billy Gilbert Shelter in the upper parking lot with staggered start times for each distance. The 50K race begins promptly at 7:00 a.m., while runners tackling the shorter route can expect to hit the trail at 8:00 a.m. Both courses feature predominantly single-track trails, weaving through lush forests and crossing serene creeks that add an element of unpredictability. For those choosing the 25K option, the course loops around Devil’s Ice Box Trails before venturing across Highway 163 to High Ridge Trails for two additional laps. The full marathon equivalent (50K) follows this same route but doubles back on itself, offering runners a chance to experience each segment twice. ### Race Day Logistics Race day registration is not available; all participants must pick up their packets and check in at the Billy Gilbert Shelter either Friday between 3 pm - 6 pm or Saturday before race start. The park's GPS coordinates are provided for easy navigation: 5575 Missouri 163, with a precise location pinpointed as 38.880933, -92.333980. ### Aid Stations and Amenities Aid stations along both routes provide essential hydration and nutrition to keep runners fueled throughout the race. For the 25K course, aid is available at Grasslands and High Ridge trails twice each loop. The 50K route includes these same points but also features a critical stop after completing the first half of the full distance back at the start/finish line. ### Time Limits A strict eight-hour time limit applies to both races, ensuring that runners remain on course within a manageable timeframe and allowing for efficient race management. Participants are reminded not to litter; instead, they should carry out any waste generated during their run. ### Entry Fees and Cancellation Policy Entry fees cover the cost of participation and include necessary processing charges: $72.06 for 50K runners and $61.43 for those opting for the shorter distance. Race day registration is not an option, nor are refunds or transfers allowed once a runner has signed up. ### Post-Race Celebrations After crossing the finish line, participants can refuel with complimentary burritos from Pancheros Burritos starting at 11 am. Be sure to have your bib number handy for meal pickup; it will be marked by race officials upon redemption of this benefit. The Rock Bridge Revenge Facebook Group serves as a hub where runners share updates and engage in discussions leading up to the event, fostering camaraderie among participants before they hit the trails. Join us at Rock Bridge State Park and immerse yourself in one of Missouri’s most challenging trail running experiences. With breathtaking scenery and supportive communities along the way, this race promises an unforgettable adventure for all who dare to take on its rugged terrain.
