Held on the third weekend of October, the MDI Marathon is an annual event full of fun activities built around the big 26.2 mile marathon run, a USA Track & Field certified event. Festivities begin Friday evening with the Pre-Race Expo in Bar Harbor, where race participants can pick up their race packets complete with timing chip, race bib number, and other important information. The Breakfast Fun Run on Saturday starts with a 1.8-mile run for race participants and family and friends followed by a delicious breakfast. The Pre-Race Pasta Dinner at MDI High School in Mount Desert on Saturday evening, hosted by the high school’s music program as a fundraiser for their kids, is all about carbo-loading for the big race. Sunday morning at 8 a.m. is marathon race start time, an exciting moment for runners and supporters. Cheer along with crowd, then head for the finish line to do it again! And that evening, the Post-Race Dinner and Party celebrates the accomplishments of the runners.
