2026 Deer Lake 5 Mile Trail Run

Get ready for an exhilarating return to nature with the revived Deer Lake Trail Run! After a seven-year hiatus and an exciting change in ownership, the Deer Lake Outdoor Center invites you to challenge yourself on a 5(ish)-mile trail run or hike, boasting a heart-pumping 500 ft of elevation gain. Immerse yourself in the beauty of rural Killingworth, CT as you navigate a true trail course filled with scenic views, diverse terrain, and natural obstacles like rocks and roots. Strive for glory and vie for awards across various age categories, and if you're quick enough, snag one of the first 100 entries to earn a commemorative T-shirt! Mark your calendars for an adventure-packed day and note the tiered entry fees - early birds get the best deal. Remember, registration is bright and early, so don’t hit snooze! And let’s keep it wild and focused - this event is all about human endurance, so please leave your furry friends at home.
