Spring Fling 600

The Spring Fling 600 is a versatile endurance trail event scheduled for Saturday, May 9, 2026, hosted by the CT Trailmixers at YMCA Camp Sloper in Southington, Connecticut. Now in its eighth year, the event centers around a roughly three-mile loop through varied terrain, offering options for both beginner trail runners and seasoned ultramarathoners. The signature "600" refers to the 10-hour (600-minute) time limit, during which participants can complete as many laps as they choose. New for 2026, the event also features a fixed 6-mile race and the "Fling Fanatic" series for those looking to compete in both the spring and fall editions of the race.
