Half-Marathon General Information

Start TIME & Location ➤Half

October 18th, 2020 - 8:30AM (eastern time)
5 Manchester Road, Northeast Harbor - Maine

There is no early start time option for the Half-Marathon. If you are walking the Half-Marathon please self-seed yourself in the starting field so that faster runners are in front of you. We ask that you do this to help avoid collisions between participants in this congested area.

Also, please keep in mind that the faster Marathoners will “catch you” on the course. The first runners will come up on you very quickly. Please yield to them. This means you must proceed single file when faster runners are present. DO NOT jog/walk 2-3 abreast after the runners start to catch you. Failure to do so could result in a collision and serious injury.

There is an 4-hour course limit. This means that you must be able to maintain an average pace of 18-minutes per mile.

The course and finish line will close at 3:00PM for all events.

Please note: There is no Early Start available; all Half-Marathon participants will start at 8:30AM.

Bib Numbers ➤Half

Half-Marathon participants are assigned RED personalized bib numbers. In the event that a Half-Marathon participant is fundraising for charity through our CrowdRise platform, they will be assigned a PURPLE bib number. 

Half-Marathoners will be issued TWO (2) bib numbers. The bib with your name and number must be worn clearly visible on your front. The bib that says “HALF” must be worn on your back. (The back bibs are intended to help full marathoners identify their competitors. Neglecting to wear your second bib number is grounds for disqualification.)

Please keep your personal information (submitted at the time of registration) up to date. If your half-marathon personal best time changes before race day, be sure to let us know. You can update your personal information by following the directions found on our FAQ page.

Transportation to start ➤Half

We highly recommend using the provided bus transportation to the start in Northeast Harbor. You will need to be wearing a RED half-marathon bib number to board. These buses will leave from the Village Green in Bar Harbor beginning at 6:15AM, and will run continuously as filled until 7:15AM. It is very important that you do not try and wait for the “last bus” or you could miss the start of the race. (This is because we cannot possibly transport all the runners at one time.)

Buses will unload at the Neighborhood House, where you can check your bag and stay warm until the race starts. The starting line is an easy walk from here. (Approximately ¼-mile.)

Bus transportation to the start is one-way. Shuttle buses from the Finish Line Festival in Southwest Harbor are non-stop and will bring passengers back to the Bar Harbor Village Green, where you originally boarded the bus to go to the Half-Marathon start in Northeast Harbor.

Bar Harbor - All parking options in downtown Bar Harbor are an easy walk to the starting line, located at 200 Main Street.

Please note that both paid and permit parking rules are not enforced until 12:00PM on Sunday. (This means that you will need to pre-pay for parking; if you select two hours, you will be able to park until 2PM.) See complete parking guidelines and maps online HERE.

DO NOT park on Main Street south of the starting line! (i.e., the marathon course.)

Paid and permit parkin grules in Bar Harbor will be enforced during MDI Marathon weekend. See included map of downtown Bar Harbor for parking locations. In addition to paid parking, there is also free parking available at Conners-Emerson School, located at 11 Eagle Lake Road. Finally, permit parking will be lifted on race day on the following streets: Glen Mary Road, Shannon Road, Park Street, and lower Ledgelawn Ave (south of Park Street only).


Northeast Harbor - Downtown Northeast Harbor, including Main Street, will be very busy. Please do not park on Main Street as this is the Marathon route. Please park at the Marina or in the town lot behind the Old Firehouse Museum. Shuttle bus transportation from the Finish Line in Southwest Harbor is non-stop back to Bar Harbor. If you are leaving a car in Northeast Harbor you must have your own plan to get back to it.

The baggage check vehicle will be stationed at the Neighborhood House in Northeast Harbor, about ¼-mile from the start. You must check your bag 30-minutes prior to the race start. No bags will be accepted after 8:15AM. Bags will be transported to the Finish Line in Southwest Harbor.

When packing your checked bag, keep in mind that the Finish Line Shuttle Buses back to Bar Harbor don't start running until 12:00PM. Be sure to include a few warm layers so you'll be comfortable as you cheer on your fellow race finishers!

Race officials are not responsible for lost or stolen items. Please leave any and all valuables with family or friends. Unclaimed bags will be donated to charity.

Half-Marathon Course Information

Course Description ➤Half

USATF Sanctioned & Certified: ME16012JK

Our 13.1-mile foot race starts at the half-way mark of the full marathon course in the picturesque village Northeast Harbor.

The first miles of the course gently roll along the mouth of the only true fjord on the Atlantic Coast, lined with the pink granite that makes up most of the area, Somes Sound nearly bisects the entire Island. (These first miles are literally on the edge of this remarkable topographical marvel!)

The low point on the course, will come at about mile 3 along the eastern shore of Somes Sound. This is followed by a slight rise to mile 4, and then a sharp incline from 4 to 5, heading up to the cliffs of the interior end of the fjord. Running hills makes for powerful camaraderie. Mile 6 is a giveback downhill, and then the gradual ascent from mile 7 to 12 begins in Somesville, the quintessential New England village.

Approaching mile 13 will be the high point of the course, literally and figuratively, and affording great views. And it will be all downhill from there. The final 1.1 miles to the finish line in charming Southwest Harbor descends; yes, that last 2,000 meters will be all down. But what a sky-high feeling of accomplishment it will bring!

Rules of the road ➤Half

The Marathon, Half-Marathon, and Team Relay are all run on the same course. The Marathon & Team Relay start in Bar Harbor, while the Half-Marathon starts in Northeast Harbor.

Portions of our course are open to local traffic. Please be respectful of our neighbors who are sharing their roads with us. Course marshals and public safety officials will be directing traffic at key intersections. Please be aware of vehicles around you. If wearing headphones, which we strongly discourage, please remove one ear bud and keep the volume down. (Noise cancelling headphones are strictly prohibited!)

Our Half-Marathon distance has been measured on the LEFT side of the road, FACING oncoming traffic. Do not run far out in the traffic lane, or cross the center line, over to the right side of the road or you will not be running the entire 13.1-mile distance, and you will risk being disqualified. It is very important to note that parts of the course will remain OPEN to local & volunteer automobile traffic.

The ONLY section of the Half-Marathon course closed to thru-traffic is along Somes Sound on Sargeant Drive. (Approx. miles 1 - 4.5.) On this section of the course that is closed to thru traffic, runners should use caution, but may take the shortest possible paved route, on either side of the road, to cover the accurate marathon distance. (Note: Even on the sections of the course closed to thru-traffic, there may been limited local traffic or course volunteers.)

It is the participant’s responsibility to know the course.

Disqualification: Anyone seen running or walking on the RIGHT side of the course, (except along Sargeant Drive –see above) will be doing so in an unsafe manner and in violation of the rules of the event. Since the course has been measured on the LEFT facing traffic any such violation may result in running less than the full distance and the participant risks immediate disqualification.
