For nearly five decades, the Catalina Island Marathon has drawn runners from around the world to one of California’s most breathtaking and challenging races. On March 8, 2025, the 48th annual event will take place, solidifying its status as the state’s oldest trail marathon and the only one traversing an island in the Pacific Ocean. With stunning ocean views, rugged terrain, and a deep connection to Catalina’s natural beauty, this event remains a bucket-list race for seasoned marathoners and adventurous first-timers alike.
Runners will take on a variety of courses, ranging from the full 26.2-mile marathon to shorter, more accessible distances, including the 10K, 5K, and a special kids’ race. The event serves not only as a test of endurance but also as a significant fundraiser for the Catalina Island Conservancy, which works to preserve and protect the island’s unique ecosystem.
The marathon kicks off at 7:00 a.m. in Two Harbors, challenging participants with steep climbs, sweeping descents, and some of the most breathtaking views of the Pacific Ocean imaginable. Unlike traditional road marathons, this trail race winds through the rugged peaks and valleys of Catalina Island, where runners may encounter native wildlife, fields of wildflowers, and panoramic ocean vistas. The challenging terrain makes this course both rewarding and demanding, requiring endurance, strategy, and determination to reach the finish line in Avalon.
For those looking for a shorter challenge, the 10K and 5K races begin at 8:15 and 8:30 a.m., respectively. The courses allow runners to experience a portion of Catalina’s stunning landscape while still offering a formidable challenge. The kids’ run, open to ages 3 to 13, provides an opportunity for younger participants to experience the excitement of race day, with a fun and supportive atmosphere to encourage the next generation of trail runners.
Beyond the personal challenge, the Catalina Island Marathon benefits the Catalina Island Conservancy, an organization dedicated to protecting the island’s natural beauty. By participating in the race, runners directly support conservation efforts that maintain trails, protect wildlife, and preserve access to Catalina’s stunning landscapes for future generations. In keeping with this mission, the marathon is also a cupless event, meaning runners must carry their own hydration systems or purchase reusable soft cups to help reduce waste and minimize the environmental impact on the island.
Awards are given to top finishers across all race distances. For the marathon, custom awards will be presented to the overall top three male and female finishers, as well as the top three in each age division. Runners who are island residents can choose to compete in the exclusive Islander Division, further fostering Catalina’s strong running community. Similar awards are given in the 10K and 5K, recognizing top performers in each category.
While completing the Catalina Island Marathon is an accomplishment in itself, the event also serves as part of the prestigious Catalina Island Triple Crown Challenge. This challenge requires participants to complete three of Catalina’s signature trail races — the Avalon 50K or 50-Mile race, the Catalina Island Marathon, and the Catalina Island Half Marathon — within a 12-month period. Those who conquer all three earn exclusive finisher swag, including a custom belt buckle, a Hi-Tec finisher jacket, and trail running shoes.
Signing up for the Triple Crown Challenge also comes with a discounted race package, allowing runners to experience all of Catalina’s most renowned courses while saving on entry fees. For trail runners seeking the ultimate test, this challenge is the perfect way to push limits while soaking in the island’s breathtaking scenery.
