_ The 2018 Mare Island Half Marathon, 10K, and 5K:

We are so excited to be able to host our first run only event this coming up October. We will have Half Marathon, 10K and 5K runs across to the other side of the straight on Historic Mare island.

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. All courses are still going through the approval process and some tweaks may be made, but the overall feel for the race should not alter too much. Parts of the run through the San Pablo Bay Trail are unpaved.

All participants will receive a tech shirt and finishers medal. Awards will be available for Male and Female of every category that has a minimum of three entrants. Teams will be awards in one mixed category and will also need 3 team entries for awards.

Pre-registration will close on October 3rd. Day of registration will be available however discounts will not apply. Shirt sizes will only be guaranteed for registrations prior to September 15th. Any registrations after that will be first come first serve on the sizes that are ordered.
