Founded in 1963, the Equinox Marathon is the premier distance running event in Interior Alaska. Held amid golden fall colors, this event will test your running abilities and mental fortitude — but with a marathon run, marathon hike and 3-person relay, it's accessible to just about any runner or hiker. The iconic event, held mostly on trails with some dirt and paved roads, starts and finishes at the University of Alaska Fairbanks and includes a challenging climb up Ester Dome and a long descent back to campus. Marathoners will climb 3,300 feet of vertical gain. The relay is renowned for being festive and teams will combine to complete the full course in three 8-to-9-mile legs. Race-day weather and course conditions can range from dry trails and mild temperatures to wind, snow and mud. There are nine aid stations and a great vibe at the finish area. The event is organized by Running Club North. NOTE: Online registration closes at 7:00 p.m. on Friday, September 18!
