The Booneville Backroads Ultra invites runners to explore the stunning rural landscapes of Iowa through its diverse course offerings. Spanning from the challenging #tuffest10k to grueling 50k, 100k, and even a full 100-mile trek, this ultra event promises an unforgettable journey for all levels of endurance athletes. In 2026, the race organizers are introducing significant enhancements to elevate the runner experience. For starters, detailed course markings will be implemented on the 50k, 100k, and 100-mile routes, complementing the traditional cue sheet system that has guided runners for over a decade. This change aims to reduce barriers for newcomers while maintaining the race's adventurous spirit. To encourage greater female participation in ultra distances, Trail Sisters members will receive special discounts on registration fees for the longer races. As women continue to set new benchmarks in trail and ultrarunning, this initiative seeks to foster an inclusive environment where everyone can push their limits. Another exciting update is the allowance of crew support along the course beyond aid stations. This provision aims to enhance runners' success during challenging conditions by enabling them to receive additional assistance from supporters. However, strict guidelines will govern how crews operate on-site to ensure fair play and safety for all participants. The Booneville Backroads Ultra remains true to its roots as a grassroots event characterized by unpredictable weather, rustic level B roads, supportive small communities, and rugged terrain. These core elements create an authentic challenge that tests runners' mettle while celebrating the beauty of Iowa's countryside. As you venture onto these backroads this fall, prepare for an adventure that combines natural splendor with a rich trail running tradition.
