RYR Endurance Race Weekend 2026

The RYR Endurance Race Weekend is an annual event held in Owensboro, Kentucky, featuring a marathon, half marathon, 50K ultra, 10K, and 5K spread across two days. The marathon structure is distinctive: a Saturday marathon with a 9-hour time limit, followed by a Sunday competitive marathon for those aiming for a Boston qualifier or a personal best. Both marathons utilize the same USATF-certified course, which also includes the area's first certified marathon and half marathon routes. The course is a multi-loop out-and-back on an asphalt greenway with minimal elevation gain, following a creek, passing two lakes, and crossing wooded areas. This loop design allows spectators to view participants multiple times from a single location, and runners have access to standard aid stations as well as personal support tables. The Saturday marathon shares the course with the half marathon and 50K, whereas the Sunday marathon has a limited field and runs exclusively. All participants receive a shirt, all finishers receive a substantial medal, and all profits benefit the Wendell Foster Center.
