Welcome to the Catalina Island Eco Marathon

We welcome you, the athlete, to one of the most beautiful marathons that you will ever run in the United States. The Catalina Eco Marathon will start and finish in the town of Avalon, no morning boats to catch, no seas to worry about, just a leisurely stroll to the start line and back into town after 26.2 miles of some of the most beautiful, rugged and breathtaking trails you will experience.

During the course of the marathon, you will traverse single track trails, ridgelines, and vistas that will afford views of the Pacific Ocean – from BOTH sides of the island. You will run through three entirely different eco-systems and see the plant life and animal life in each. Don't be surprised to see buffalo on the course, seals in the water, and bald eagles overhead.

Named "Best Island Run" by Runner's World Magazine- April 2012

What runners are saying about Catalina Eco Marathon

  • I absolutely loved the Catalina Eco Challenge Marathon. After running both marathons on the island, I can say with confidence that the Eco Challenge was my favorite because it was more challenging and scenic than the other one. The course was scenic, challenging, adventurous and well laid out. thank you for your efforts and I will be back!
