The Catalina Island Marathon is a long-standing and iconic destination race that brings runners to the rugged, windswept beauty of Santa Catalina Island. First run in the early 2000s, the event has grown into a must-do for trail and road-marathon enthusiasts who want a challenging, picturesque alternative to mainland races. Traditionally held in March, the race's timing and island setting create a festival-like atmosphere in Avalon, with runners arriving by ferry the morning of the race or the day before to take in the small-town charm, pre-race pasta dinners, and expo. The event has been conducted on a USATF-certified, Boston-qualifying course, making it attractive to competitive runners chasing qualifying standards as well as recreational runners seeking a memorable marathon experience.
The course is point-to-point along Catalina Island's coastal roads and rolling interior hills, featuring sweeping ocean vistas, rugged cliffs, and stretches through chaparral and Catalina's unique island habitat. Expect significant cumulative elevation gain (approximately 4,200 feet) with steep but runnable climbs and rewarding downhill sections as you approach Avalon, making the route as technically and physically demanding as it is scenic. The small field size fosters a supportive, community-oriented atmosphere—aid stations are friendly and well-stocked, local volunteers cheer along the route, and the finish in Avalon offers celebratory views of the harbor, island culture, and post-race refreshments. Runners should plan for island logistics (ferry schedules and limited accommodations) but will be rewarded with one of the most memorable marathon backdrops in California.
