Cool start — fast day potential, warming through the race

A cool 47°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 60°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 75% is worth noting for effort level, especially in later miles.

It shares the marathon route for the first 6.5 miles before turning back toward Portland. The opening and closing 1.5 miles along Back Cove are flat, with a mix of rolling hills and flat sections between, and views of Casco Bay and fall foliage along the way.
