This triathlon kicks off with a refreshing 0.4 mile swim in a pristine, spring-fed lake right in Williamstown, NJ, followed by a speedy 13 mile bike course on flat terrain with generous bike lanes. You'll finish with a 5K run across the scenic Autumn Lake Winery grounds, where you'll navigate hard-packed dirt trails, grass, sand, and loose dirt while circling two lakes and passing through the vineyard.
