San Diego 50 & Trail Runs 2027

San Diego 50 & Trail Runs offers a trail race series in San Diego centered on a 50-mile ultra. Shorter distances accommodate marathoners, relay teams, new trail runners, parents with strollers, and children. The 50M is presented as a suitable first 50-mile race or an accessible ultra. The event also features a trail marathon, a half marathon, the Summit Chase 10M, the Valley 5M, the Stroller Trail 5K, and a 1 Mile Fun Run for children 10 and under. Raptor Ridge is a key course feature. The trail marathon crests at Raptor Ridge, and the Summit Chase 10M goes to the summit and back, with the winner taking the title. The marathon relay divides the marathon into two 13.1-mile segments, with handoffs at Piedras Parking Trail Head Parking Lot rather than using a shuttle. The Valley 5M and Stroller Trail 5K are flat courses, and the kids' mile is untimed but includes finisher medals. The series is cupless; participants must provide their own bottle, cup, or hydration pack for aid stations.
