Thank you for your interest in the 2025 Mare Island Half sponsored by the Mare Island Brewing Company. We expect to be running from the Mare Island Brewing Company coal shed location on Mare Island and stay on the island for the full race.
Our Half Marathon course will take you along the historic naval yard on the east side of the island, to the highest point of Mare Island for beautiful views of the Bay, Mt. Diablo, and Mt. Tamalpais. It will then run you down by the Old Admiral housing and out to the Mare Island portion of the San Pablo Bay trail on the western side of the island. The 10K will take you by the Old Admiral housing and the San Pablo Bay Trail before heading to the finish. The 5K race will run by the Old Admiral housing before heading to the finish. Parts of the run through the San Pablo Bay Trail are unpaved. As the Island is going through some revitilazations there may need to be course changes to allow for safe running we will keep this listing and our posted maps updated if we are required to make any changes.
All pre-registered participants will receive a t-shirt and finishers medal. Awards will be available for Male and Female of every category. We expect to have categories of <19, 20-29,30-39,40-49,50-59 and 60+
Shirt sizes will only be guaranteed for registrations prior to June 5th.
