Catalina Marathon
The Catalina Marathon runs a rugged point-to-point course across Santa Catalina Island, from Two Harbors to Avalon. It is genuinely hard, genuinely remote, and nothing like a road race.
Race Overview
The Course
Race-Day Weather
Mid-March on Catalina is generally mild, with a cool start in the low 50s and afternoon temps topping out around the mid-60s. That sounds comfortable, but the course climbs well above sea level and the ridge can be exposed and windy. Dress in light layers you can shed early. The bigger wildcard is that conditions on the island can shift quickly, so check the forecast the morning of the race. On a calm day it is close to ideal running weather. On a windy day you'll feel it.
