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!
