San Diego 50 Mile & Trail Marathons

San Diego 50 & Trail Runs is a multi-distance trail running festival staged at the San Pasqual Valley Staging Area in Escondido, California. The lineup includes a 50-mile ultramarathon, a Trail Marathon (plus a 2-person relay), a Trail Heavy Half, Summit Chase 10M (with a youth version), plus Valley 5M, Stroller Trail 5K, and Elevated Youth 1-Mile. The rugged course showcases San Diego County trails and the summit of Raptor Ridge, with a cupless aid-station policy.

After racing, participants enjoy an Elevation Culture finish-line camp with drinks, food, music, and community. Pacers are allowed for the last 7 miles of the 50M, and finishers receive shirts, wooden medals, and a reusable cup. Visit the organization's website for the most recent information.
