5 running events in Southington, Connecticut

For 6 weeks, young athletes across Rhode Island and Massachusetts have been swimming, biking, and running toward this one incredible goal!

This finale event brings together participants from Race4Chase programs across both states to celebrate their hard work, determination, and confidence gained throughout the summer. It’s more than a race, it’s a powerful celebration of youth achievement, healthy living, and community support.

While this event is exclusively for Race4Chase participants and not open to public registration, we need enthusiastic volunteers to help make it a safe, smooth, and unforgettable experience for every child crossing that finish line.

Welcome!

Come join the CT Trailmixers for the annual Fall Fling 400 trail races! This year we’re again offering race entry options. These races are a great opportunity to give trail running a try.

Entry Options

Fall Fling 400 You can run as many loops as you’d like of a roughly two-mile trail course as long as you're done within 400 minutes (six hours 40 minutes). You’re not required to run an ultra distance — at least 28 miles (or 14 loops) — although many people will. Whether you want to try your first trail race, or go for an ultra distance, this event is for you.

Spring Fling 4 Miler Complete 2 laps of the roughly two-mile course.

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

We aim to make trail running 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.
