Catalina Island Half-Marathon & 10K

Catalina Island Half-Marathon & 10K is held in Avalon, California, on November 14, 2026. The half marathon (13.1 miles) is run on trail and starts at 8:00 a.m., the 10K follows at 8:15 a.m., and a 1K kids' fun run goes off at 10:00 a.m. The half begins in Avalon, passes the historic Wrigley mansion and then turns inland for several hard miles of climbing before topping out on views of the Pacific and possibly two of the other Channel Islands. It drops back down through the Wrigley Memorial to finish in Avalon, while the 10K covers the hills above town.

Expect the climbs to dictate your day. Pace the early miles by effort rather than by the watch, and hike the steepest sections instead of grinding them out. Sustained downhill running takes its own preparation, so work long descents into your training in the two months beforehand.
