Spring Fling 600

Spring Fling 600

The Spring Fling 600 is organized by the CT Trailmixers at YMCA Camp Sloper in Southington, Connecticut and takes place on May 9, 2026. The event uses a roughly three-mile looped trail that starts and finishes at the main pavilion and offers varied terrain and scenery on a well-marked course.

Race options include:

• Spring Fling 600: Run as many ~3-mile loops as possible within 600 minutes.
• Spring Fling 6 Mile: Complete two laps of the roughly three-mile course.

Both races use chip timing and laps are counted on a public display at the start/finish area. For the 600 minute event, only laps completed within the 600 minute time limit count; laps finished after that limit are not included. Participants may take breaks during the day and rejoin the course; when done racing, runners should inform volunteers so organizers know they have left the course.

Registration is accepted online only, fees include processing charges, and CT Trailmixers members receive a 25 percent discount via a member coupon. Race-day registration is contingent on available openings. Total entry caps are 150 for the Fling 600 and 50 for the 6 Mile.

All finishers receive a CT Trailmixers gift and a finisher’s medal. Top male, female, and non-binary competitors are recognized. Race proceeds support local organizations including the Southington YMCA, the Connecticut Forest & Parks Association, and the CT Trailmixers Shoe Scholarship Program.

Connecticut spring weather is variable; the event has often been wet and muddy. Visit the organization's website for the most recent information.
