*** There is NO RACE DAY packet pickup. ***
The Mount Desert Island YMCA is committed to environmentally conscious and sustainable racing, as our course travels through Acadia National Park. A large amount of our waste was paper cups, in fact over 6000 cups per race!
For 2027, we are a CUPLESS event. All half marathon runners will receive a race branded reusable silicon cup at bib pick. You can also bring your own personal reusable cup, handheld water bottle or hydration pack. 10k runners have the option of purchasing a race branded reusable silicon cup during the registration process if registering before March 1.
Thank you for helping us protect and maintain the natural beauty of Acadia National Park!
