Event Details

Come join the CT Trailmixers for the seventh annual Spring Fling 600 trail race on Saturday, May 27 starting at 8:00 am ET at YMCA Camp Sloper in Southington, CT!


The idea is simple: Run as many loops as you’d like of a roughly three-mile trail course within 600 minutes (10 hours). Whether you want to try your first three-mile trail race or aim for your first ultra, this event is for you.

The CT Trailmixers welcome folks who are new to trail running! This 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.


  • 6:00 am: Bib pick-up begins
  • 7:45 am: Pre-race briefing
  • 8:00 am: Race begins
  • 6:00 pm: Race ends


Advance pre-registration through May 17:

  • $30 for members (Thereafter $50)
  • $50 for non-members (Thereafter $70)

On-line race-day registration will be available if there are still openings. Total registration will be capped at 250.


The race will be timed, and your laps will be counted, using chip timing. You can check your lap counts on a large monitor that will be on display at the start/finish area. Only laps completed within the 600 minutes will count. If you finish your last lap and it’s past 6:00 pm, it won’t count.

The course will start and finish at the main pavilion at Camp Sloper. When you’re done with racing, please tell the volunteers so we know you’re leaving the course. You can take breaks during the day and rejoin the race whenever you like.


All participants will get a CT Trailmixers-branded gift and a finisher’s medal upon completing their race.

Additionally, we’ll recognize the top male, female, and non-binary competitors who complete the most full loops in the shortest time within 10 hours (600 minutes). If more than one runner in a category completes the same longest distance, the winner will be the runner who finishes that distance first.


Race proceeds will go to a variety of local organizations, including the Southington YMCA and the Connecticut Forest & Parks Association. They will also go to the CT Trailmixers Shoe Scholarship Program, which gives free shoes to kids in need who want to run cross-country or track in school.


Connecticut weather in early May can be cool and rainy or sunny and warm. The Spring Fling has historically been a wet and muddy affair, so come prepared. Pay attention to the forecast.
