Deer Lake 5 Mile Trail Run

The Deer Lake 5 Mile Trail Run is held in rural Killingworth, CT on the Deer Lake Outdoor Center property. Deer Lake Outdoor Center is a 501(c)(3) nonprofit focused on accessible outdoor education and protects more than 250 acres of green space with miles of trails.

The main course is a challenging, 5(ish)-mile trail that includes almost 500 ft of elevation gain. The route traverses the property on well-marked trails, offering scenic views and varied terrain. Runners should expect technical trail conditions with rocks, roots and possible mud.

New for 2027, there is a timed 1(ish)-mile trail course for kids and the young at heart. That course is also technical and will be timed, with awards for top finishers.
