What is the course like?  

The course is a ½ marathon, 13.1 miles. It is a challenging loop course, with the start in downtown Bar Harbor and finish at the Bar Harbor athletic field across from the MDI YMCA.  This year our course will take a different route through Acadia National Park due to park maintenance. We will return to our usual Acadia National Park course in 2022. The 2021 course is NOT certified. 

Are there adequate bathroom facilities? 

Yes!  And they are real bathrooms – not porta-potties! We have bathrooms available at the start & finish of the race and 2 bathrooms on the course itself. The race course restrooms are near the water stations at (approx) mile 4 and also at (approx) mile 10.

Can we walk the race?  

Yes. We ask that walkers start at 6:00am to ensure all race participants are out of the park by 9:15am. Please note, ALL 5K participants start at the same time: 8am whether you are walking or running.

Do I get a shirt?  

Every pre-registered half marathon runner and walker is guaranteed a t-shirt and a custom award. The first 50 to register for the 5K will be guaranteed a t-shirt. 

Are there enough water and sports drinks on the course?  

We have 6 water stations with sports drink included at miles 5 and 10.

Do I get an award, even if I come in last?  

Yes!  Every half marathon & 5k finisher receives a custom medal.

How about parking?  

The Y offers free parking. Parking meters in the field adjacent to the athletic fields and on main street will be turned off during the event, but will be turned on afterwards. Please be mindful of wen the parking meters are turned on.

What are my lodging options?  

For lodging options contact the Bar Harbor Chamber of Commerce. Their website has a list of campgrounds, motels, and hotels.  Many people who participate in this race lengthen their stays in order to further explore Acadia National Park and Mount Desert Island.

Refunds?  Due to a limited amount of spaces in the race, and the fact that this is an important fundraiser for the YMCA, race fees are non-refundable and non-transferable.

Is this race capped?  

Yes. Due to Acadia National Park permit restrictions, only 400 runners may participate. This means lots of elbow room along the course. Registration Fee for race includes the cost of a National Park Pass. This will be included in your race packet. Park passes are Individual passes and are good for one week.
