Catalina Island Marathon

The Catalina Island Marathon, along with its 10K and 5K distances, takes place in Avalon, California on Catalina Island. The event features the full marathon (26.2 miles), a 10K (6.2 miles), and a 5K (3.1 miles), plus a Kids Run, drawing runners to the island’s scenic trails. It is the oldest trail marathon in the state and serves as California’s State Off-Road Marathon Championship.

Runners traverse trails through the Catalina Island Conservancy, enjoying sweeping ocean views, rolling green hills, and rugged coastal scenery. The weekend also offers a Triple Crown challenge, creating a bucket-list, island-running experience with a supportive, island atmosphere.
