Mare Island – Half Marathon, 10K and 5K routes

The run will kick-off from outside the event's major sponsor - Mare Island Brewing Company - who will also be supplying a free beer, post-race.

From here, runners will make their way through the iconic naval yard on the Island's Eastern edge and take in stunning views of the Bay, Mt Diablo, and Mt. Tamalpais.

After, you will speed down to the Old Admiral Housing which includes St Peter's Chapel and loop round to the Western side of the Island.

The 5K and 10K will pass the Old Admiral Housing, before then looping back toward the finish.

    the course is a hodgepodge of stuff. A killer mile up at mile 3 then a race down, then 5 miles on packed dirt, the rest on roads. Mare Island is beautiful though and the parking is great. Strange to have no electrolytes on course for the 1/2 and no food at the end. will do it again
