*** 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 is paper cups, in fact over 6000 cups per race! We are making steps over the next few years to move to "cupless" events.
For 2026, we are encouraging participants to bring their own reusable cup, handheld water bottle or hydration pack. We will still have paper cups at all 6 water stations this year, but with your help we can start reducing our waste and impact on our sensitive environment.
Thank you for helping us protect and maintain the natural beauty of Acadia National Park!
