Mercer Island Half Marathon, 10k

  • Mercer Island Community and Event Center (map)

Every year, thousands of runners and walkers cross the finish line at the annual springtime running of Mercer Island Rotary’s Half Marathon which includes 10K and 5K races along with a Kids’ Dash, all designed to help raise funds and awareness to fight colon cancer and to benefit an array of other charitable causes supported by the Mercer Island Rotary Club Foundation.

While the 10K race is for runners only, both the 13.1-mile half marathon and the 5K welcome walkers as well as runners. 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 uphill and downhill challenges.
