Event Details

The Observatory Loop Relay is a trail relay race for teams of two. Each team runs the Observatory Loop, which is a one mile trail, four times. Team members alternate laps and hand off a baton at the end of each lap. This means each runner completes the loop twice, with a break between laps. The event takes place in Griffith Park, Los Angeles, CA.

The race is held at night and headlamps are required for all runners. There are two registration types: one for full teams and one for individual runners who will be matched with a partner. A branded baton is included for participants.

This edition is currently sold out, but a waitlist is available. Visit the organization's website for the most recent information.
