Catalina Marathon

The Catalina Marathon in March 2027 takes you around Catalina Island on a flat to gently rolling road course, making it a solid choice if you want to chase a fast time without fighting significant elevation. The sea-level location means you won't have altitude concerns, and the relatively gentle terrain keeps the physical demands straightforward compared to hillier races. Be prepared for island-specific logistics, as getting to the start requires ferry access, so factor that into your race weekend planning. The early spring timing puts you in decent racing weather for Southern California, though always check the race website closer to the date for course details and any quirks that come with staging a marathon on an island. If flat, predictable terrain appeals to you and you don't mind the extra travel arrangements, this is worth considering for a personal record attempt.
