The Adirondack Marathon starts on Main St. Schroon and heads north. The course is one full loop around Schroon Lake on paved roadways (except for one half-mile stretch of gravel road in mile 3).
The first four miles are rolling or flat. Miles 4-12 feature short, but steep hills along a two-lane country road on the east side of the lake.
Miles 13-18 are flat, along the east shore. Then, there are long, gentle hills on Route 9, leading north to the finish in the town of Schroon.
