2026 Deer Lake 5 Mile Trail Run

It’s back! (and hopefully back for good!) After a 7 year pause and a change of ownership, the Deer Lake Trail Run is back. Deer Lake Outdoor Center, formerly Deer Lake Scout Reservation, is a 501(c)(3) nonprofit organization dedicated to accessible outdoor education while protecting their more than 250 acres of green space and miles of trails. Come to rural Killingworth, CT to run (or hike) the Deer Lake Trail Run. The challenging 5(ish)-mile course, involving almost 500 ft of elevation gain, traverses the 250+ acre property and offers many scenic views as you navigate the ever-changing elevations on well-marked trails. This is a true trail course, and the technical nature of the terrain will mean that you will be exposed to rocks, roots, possible mud, etc. There will be awards for male & female winners in each age group listed below as well as the overall male & female winners. T-Shirts guaranteed for the first 100 entrees, so sign up today! ENTRY FEES$30 through March 15t
