Mercer Island Half

March 22, 2020

Join us this year for the Annual Mercer Island Half! Once again, the event will kick off the Northwest running season, offering a Half Marathon Run/Walk, a 10K Run, a 5K Run/Walk, and the Half-Mile Kids Dash!
On Saturday of event weekend, participants will have the opportunity to visit the Pre-Race Expo with packet pick-up, ‘last gasp’ registration and dozens of sponsor and exhibitor booths. On Race Day, participants and supporters alike will converge on Race Village at the Mercer Island Community & Event Center to enjoy music, awards, giveaways, samples and friendly faces at our sponsor booths!

All proceeds from the Mercer Island Half benefit colon cancer prevention and other Rotary causes. With the support of event sponsors and participants, the event is able to fund an awareness & prevention campaign explaining that the disease is 100% curable with early detection.

Don’t miss out on an opportunity to be part of one of the largest runs in western Washington!!

5K, 10K, Half Marathon, Kids
