The main start and finish are at the State Park near the intersection of Lake Waramaug Road and Anderson Acres Extension; coordinates for the park are N 41 42.47, W 073 23.059.

There are four well stocked aid stations around the lake, positioned roughly 1.8 miles, 1.9 miles, 1.7 miles and 2.2 miles apart in sequence from the main start and finish. Post race food and drinks are provided for runners. Entry includes a technical T shirt, finish medals for 50K and 50 Miler finishers, and a custom belt buckle for 100K finishers; t shirt sizes are not guaranteed after March 15.
Time limits are set at 12 hours for the 50K and 13 hours for the 50 Miler and 100K, though officials may allow continuation based on conditions and safety considerations. Visit the organization's website for the most recent information.
