Adirondack Marathon

Registration is open to all runners through Race Roster on a first-come, first-served basis. There are no qualification requirements, but the field is small so it's worth signing up early before capacity is reached.

Yes, the course is USATF certified and qualifies for Boston registration. That said, the 1,500 feet of elevation gain makes it a demanding course, and only a small fraction of finishers hit BQ times, so go in with a realistic plan.

The loop course gains 1,500 feet with no net downhill to offset it. The course runs between roughly 800 and 1,100 feet in elevation, with rolling grades throughout rather than a single sustained climb. The cumulative load is significant, especially in the back half.

The time limit is 7.5 hours, which is generous enough to accommodate a wide range of paces on a hilly course.

The Adirondack Marathon is a small race with around 160 finishers in a typical year. You will spend significant stretches running without many other competitors around you.

Late September brings cool starts in the low-to-mid 40s and afternoon highs in the mid-60s. It's generally good running weather, though the combination of hills and midday warmth can make the back half feel harder than the temperature suggests.

Schroon Lake is about 90 minutes from Albany International Airport. Flying into Albany or Burlington, Vermont, and renting a car are the most practical options. There is no public transit to the race start.
