Just minutes from I-95 this mid-season Sprint/Olympic race is fast, flat and easy to get to. Staged out of beautiful Lums Pond State Park in Bear, Delaware this is a great race for elite and novice athletes alike. The freshwater swim starts with a rectangular course that parallels the shore for the first 250 meters. The bike course is super fast and completes a large loop around the park. This course is completely flat, all right hand turns and has great pavement throughout. The run course is amazing with a beautiful, heavily forested mix of single track lake views and wide open graveled walking paths. There are mountain biking, hiking and running trails galore as well as the GoApe ropes course. Or you can relax with friends post race at Stewarts Brewing Company on the way home.
