Maine Coast Half Marathon & 5k

From there, runners head south along the beaches for the first 4.5 miles with views of the Atlantic Ocean to the left and the inland marshes to the right. This section is virtually flat with only one tiny hill near mile 2.5.
Runners will cross a footbridge going over the estuary before heading inland, where the course continues the nature tour of marshes and wildlife and crosses the estuary several more times.
This section of the course is part of the Rachel Carson National Wildlife Refuge, which protects salt marshes and estuaries for migratory birds. Keep an eye out–you might see some of these birds before they fly south for the winter.
Though the second half of the race features some rolling hills, the elevation ranges from just above sea level to about 50 feet, so there are no major changes in elevation throughout the 13.1-mile course. The last mile is fully downhill as runners approaches the finish line at Wells Harbor Community Park.
Aid stations will be located at roughly every two miles along the half marathon route, stocked with water and Gatorade, and organizers add that some of the stations will also have jelly beans, orange slices, peanut-butter-filled pretzels, mint chocolate chip cookies, watermelon chunks and more as you run through them.
The half marathon is limited to the first 1,200 entrants and the marathon is limited to the first 1,000, so if you’re thinking of running this race you’re strongly encouraged to sign up early.
