Course Overview
The BURT course is a 55K loop that links a multitude of Bainbridge Island parks and trails, with 70+% (and growing) of the course being on trail. Run through the lush firs and cedars of the Grand Forests, Gazzam Lake, and Fort Ward then take in world-class water views at Port Blakely and South Beach.
​
Each loop is comprised of over 4,000 feet of elevation with a 'vert crux' of deceptively challenging switchbacks in Gazzam Lake. This thoroughly-marked course is a mix of single-track trails, groomed park trails, and road. A limited number of well-stocked aid stations are provided.
