About the race

Sycamore Canyon Trail Races take place on a loop course at Goodman Ranch Sycamore Canyon Preserve, just east of San Diego. The event offers multiple distances and formats on a repeated-lap course with notable elevation gain.

Distances:

  • 100K (102 km) solo or relay
  • 50K (51 km) solo or relay
  • Half Marathon (13.1 miles)

Each lap measures about 12.8 km (7.9 miles). Elevation gain is approximately 1400 feet per lap, totaling roughly 11,200 feet for the 100K and 5,600 feet for the 50K. The 100K solo requires completion of all eight laps by the same runner; entrants must have completed at least one prior 50K or longer event to register for the 100K solo.

Relay format: four-person relays have each runner complete two laps for the 100K relay and one lap for the 50K relay. No substitutions are allowed on race day; substitutions are permitted until 24 hours before the race. Drop bags for solo runners are designated at Race HQ and are accessible about every 11.1 km; bags should be labeled with name, bib number, and race distance.

Event provisions and rules include aid stations, a requirement to carry a minimum of 40 oz of water between aid stations, lights for running after dark, no littering, and adherence to marked trails. All entrants receive a long sleeve tech shirt and finishers receive an award; top finishers receive cash and future-race prizes. Visit the organization's website for the most recent information.
