We are so excited to be able to host our 4th annual end of summer event this coming up Labor Day Weekend. This is a new weekend for this event as we move it up from our October weekend. We will have a full morning of racing going on with Olympic and Sprint distance Triathlons, Aqua Bikes and Duathlons. This event can be completed as a team or as an individual. Also dont forget about the 5k and 10k runs accross to the other side of the straight on Historic Mare island.



The swim will take place in the Mare Island Straight where the Napa River meets the Bay. The bikers will then cross the Carquinez Straight on the Zampa Bridge into Crockett, and the run course will take the participants across the Mare Island Causeway through the Mare Island Naval Shipyard.



All participants will recieve 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 August 29th. Day of registration will be available for 10 dollars more than the last price listed during pre-registration, and discounts will not apply. Shirt sizes will only be guarenteed for registrations prior to 8/1.
