RegisterThe Autumn Lake Triathlon begins with a 0.4 mile swim in a clean, spring-fed lake in the heart of Williamstown, NJ. The 13 mile bike ride is flat and fast and includes roads with large bike lanes. The 5K run will take place on the property of Autumn Lake Winery and will take you through trails (hard packed dirt, some grass, sand, and loose dirt) around two lakes and through the vineyard.
