*** 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!

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
