Catalina Island Conservancy Trail Marathon 2026

“Anyone else going to Catalina Island Conservancy Trail Marath...? Let…”

The Catalina Island Conservancy Trail Marathon runs across the most dramatic trail terrain accessible by ferry from the mainland — a point-to-point course across the interior of Catalina Island from Two Harbors to Avalon, crossing the island's mountains and canyons on trails maintained by the Catalina Island Conservancy that are otherwise accessible only to hikers.

The marathon distance covers approximately 26.2 miles of technical trail terrain with significant elevation gain, passing through the island's interior buffalo and bison range (yes, real buffalo), the Catalina highlands, and descending to Avalon's harbor for the finish. The island's unique ecology — shaped by isolation from the mainland for thousands of years — makes the race course unlike any mainland trail marathon.

Registration fills quickly; the race has a strong following among California trail runners who value the adventure of racing on an island accessible only by boat. Ferry transportation is included in registration. The race typically runs in November when temperatures are optimal for trail running and the island's summer tourist crowds have diminished.

Catalina Express ferry service connects from Long Beach and San Pedro to Avalon and Two Harbors — the race start is at Two Harbors with finish in Avalon. Pre-race accommodation in Two Harbors (camping or the bunkhouse) or Avalon is arranged by participants. Check the Catalina Island Conservancy website for 2026 race registration and course information.
