We are so excited to host another running event on beautiful Mare Island! We will have a Half Marathon, 10K and 5K courses taking you through natural and historic sections of the island. We will be starting from the Mare Island Brewing Company coal shed location, running through over 100 years of Naval history and natural beauty, with a finish line party at the Mare Island Brew Co Coal Sheds!

Our Half Marathon course will take you through the historic waterfront along 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 including St Peter's Chapel (with the largest collection of Tiffany stainied glass in the West!) and out to the sweeping views of the Mare Island portion of the San Pablo Bay trail on the western side of the island.


The 10K will take you through the historic waterfront by the Old Admiral mansion and the San Pablo Bay Trail before heading to the finish.


The 5K race will run through the historic waterfront by the Old Admiral mansions before heading to the finish. 

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 <20, 20-29, 30-39, 40-49, 50-59, 60+

Pre-registration will close on June 22nd. Shirt sizes will only be guaranteed for registrations prior to May 29th. Any registrations after that will have a selective inventory to choose from with the remaining sizes that are ordered. Exchanges can occur once all races have started. 

Race Day registration may be available but shirts and medals will be subject to availability. 


Refunds will also not be given.
