  Come join the CT Trailmixers for the eighth annual Spring Fling 600 trail races on Saturday, May 9 starting at 8:00 am ET at YMCA Camp Sloper in Southington, CT!

  This year we’re offering some new race options in addition to the classic 600-minute race. Accompanying the Fling 600 we now offer a 6 Mile distance race, while hardened Fling races can step up to become Fling Fanatics by entering both the Fall Fling and Spring Fling.

  Entry Options

  Spring Fling 600

  Run as many loops as you’d like of a roughly three-mile trail course within 600 minutes (10 hours).

  Spring Fling 6 Mile

  Complete 2 laps of the roughly three-mile course.

  Fling Fanatic Series

  Do the double - Spring Fling 600 and Fall Fling 400!

  CT Trailmixers take pride in welcoming folks who are new to trail running! This event is a great opportunity to give it a try. We make it fun, with a well-marked course that offers a great variety of terrain and scenery. And you’ll get plenty of cheers and high-fives throughout the day — along with what some past participants have said is the best aid station spread they’ve ever seen.
