Course & Elevation
The Guam Marathon features a scenic coastal loop course starting and finishing in Tumon, the island's premier resort destination. Runners traverse the west coast passing through the villages of Dededo, Barrigada, and Yigo before returning along the eastern shoreline with consistent tropical ocean views. The course is relatively flat with gentle rolling hills, making it accessible for mid-pack runners while the warm Pacific breezes and tropical setting create a unique racing environment.
