Course Map: Mercer Island Half Marathon

From the starting line on the outskirts of Luther Burbank Park on the northern end of the island, the race unfolds along an out-and-back course that takes a clockwise loop around the island and features a wealth of rolling hills along the way, as well as a few steep uphills and downhills. The race starts at an elevation of about 75 feet above sea level and dips to a low of about 30 feet in the first mile of the race, which is followed by a gradual climb over the next few miles.
