Catalina Island Marathon

Lace up for an unforgettable adventure at the Catalina Island Marathon, 10K, and 5K on March 14, 2026, launching from the picturesque town of Avalon, California. Widely recognized as California's State Off-Road Marathon Championship and the oldest trail marathon in the United States, this iconic event promises a challenging yet profoundly rewarding experience.

The full marathon course, a rugged 26.2-mile journey, traverses the stunning interior of Catalina Island, presenting runners with an elevation gain of over 4,300 feet across its predominantly dirt roads and trails. Prepare for breathtaking coastal and ocean vistas, rolling green hills, and the unique opportunity to encounter native wildlife like bison as you navigate the mountainous ascents and thrilling descents. The 10K and 5K races offer their own scenic routes, winding through Avalon's charming streets and hillsides, culminating in a festive finish in downtown Avalon. Typical race day conditions in March bring comfortable highs around 70F and lows around 51F, with a minimal 5% chance of precipitation, creating ideal weather for tackling this formidable course.

Aid stations along the course are well-stocked with water, electrolytes, bananas, oranges, M&Ms, and pretzels, ensuring runners stay fueled. However, as a cupless race, participants are required to carry their own hydration system to help preserve the island's pristine environment. Runners consistently praise the Catalina Island Marathon for its spectacular scenery and vibrant camaraderie, often describing it as one of the most beautiful and challenging races they've ever completed, inspiring many to return year after year.
