Weather Conditions

Proper hydration and nutrition prior to the race is extremely important because Guam gets hot!! Runners can expect high 80s with humidity in the 80 to high 90 percent range, so hydrate accordingly!

Race Turnaround and Completion

All half marathon runners must reach the turnaround point in no more than two hours (by 6:00 a.m.) and must complete the race within four hours (by 8:00 a.m.). The race course will open to vehicular traffic promptly at 9:00 a.m. Runners unable to meet the time requirement will not be allowed to complete the race.

Aid Stations

Water will be available at the start and finish lines. The first aid station is approximately 1.7 km (or 1 mile) from the start. Subsequent aid stations will follow at intervals of approximately 1 to 2 km. There will be a total of seven hydration stations on the course (runners will encounter the aid stations twice – on the way out and then back) where water and sports drinks will be served. A limited number of aid stations will be offering gu gel or bananas for 10K and Half Marathon runners (refer to course map for location).
