About
Griffith Park Trail Marathon is run in Los Angeles, California, on March 27, 2027, in Griffith Park. Five trail distances are on the schedule: the 50K (31 miles) and the marathon (26.2 miles) at 6:30 AM, then the 30K (18.6 miles), the half marathon (13.1 miles) and the 10K at 7:00 AM.
Early starts and a stacked timetable send the longer fields out first, which is worth planning for on a trail marathon. Treat your target time as a range rather than a number, since surface and elevation move finishing times far more than they do on the road. The 10K and half work well as an introduction to racing on dirt; the marathon and 50K want a 16-week build with a weekly long run on trails, plus regular practice hiking the steeper sections rather than forcing a run.
