SARR Prickly Pear 50K/15K/5K

Lace up your trail shoes for the SARR Prickly Pear on Saturday, March 7, 2026, an iconic event set amidst the natural beauty of San Antonio's McAllister Park. This long-standing race proudly holds the title of San Antonio's oldest ultra-distance event, even marking the ultra-running debut of celebrated athlete Courtney Dauwalter in 2011. Offering a challenging 50K and a scenic 15K, this race caters to a range of runners looking to experience the park's renowned, mostly flat and fast single-track trails. You'll navigate a picturesque course winding through the Blue Loop, Mud Creek Loop, and Mosquito Lake trails, encountering a mix of rocks, tree roots, dry creek beds, and the distinctive prickly pear cactus. With a modest elevation gain of about 100 feet per 10.34-mile loop for the 50K, the course is described as easy to moderate, offering a true trail running experience that is both accessible and engaging.

The 50K race, which will serve as the 2026 RRCA Southern Region Ultra Championship Race, consists of three 10.34-mile loops, while the 15K is a single 9.36-mile loop. All races start and finish at McAllister Park's Optimist Pavilion #3, providing convenient access to restrooms and parking. Typical race day conditions in early March offer pleasant running weather, with highs around 74°F and lows around 53°F, and only a 6% chance of precipitation. This is a cupless race, emphasizing sustainability, so runners must carry their own hydration devices to fill at generously stocked aid stations. The 50K and 15K courses feature three water stations, while the 50K also boasts an exclusive aid station near the start/finish line for drop bags, offering an array of drinks, hot and cold snacks, sandwiches, and Wildway Granola, with dedicated volunteers ready to assist and even "pamper" ultra-runners.

Finishers across all distances will receive a medal, with 50K participants earning a special finishers hat and car sticker. Top overall and masters finishers will be awarded unique hand-sewn cactus awards, adding a memorable touch to your accomplishment. This popular event, capped at 600 runners, often sells out, so early registration is highly recommended to secure your spot in this exhilarating trail challenge.
