Griffith Park Trail Marathon - November 21, 2026
This event is a set of trail races held in Griffith Park with the start area at the Merry-Go-Round Lot 1. Multiple distances follow marked courses; organizers provide GPX files for download and ask runners to familiarize themselves with the maps before racing. Courses are marked with orange ribbon, flagging, and signage, and may be changed by the race director or park officials based on conditions.
Distances offered include:
- 50K
- Marathon (26.2 miles)
- 30K
- Half marathon (13.3 miles)
- 10K
Aid stations are positioned along each course with varying services. Stations stock a mix of sweet and salty snacks, PB&J, potatoes, fresh fruit, GU gels and electrolytes, and ice when conditions require. Bathrooms are available at selected aid stations and at the finish. Drop bags are allowed for the 50K and marathon at designated locations. Runners are required to carry a cup, bottle, or hydration pack for use between aid stations.
Event rules emphasize no littering, respectful behavior toward volunteers and other trail users, and low headphone volume to hear instructions. Poles are permitted with caution on single-track sections. Post-race food and snacks are provided; participants are asked to use reusable cups or bottles to reduce waste. Parking on race morning is free and directed by a parking crew. Visit the organization's website for the most recent information.
