Event Description

Come join the CT Trailmixers and the Southington YMCA for the fifth annual Fall Fling 400 trail ultramarathon! We’re excited to be back after a pandemic hiatus.

Here’s how it works: 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.

The CT Trailmixers welcome people 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.

Health and Safety

Even though we’re in pretty good shape here in Connecticut related to the pandemic, we will continue to monitor and follow federal, state, and local guidelines. We expect the event to be “normal,” although we reserve the right to make changes should the environment around us change.

Prizes and Goodies

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

Additionally, we’ll recognize the top male and female who complete the most full loops in the shortest time within 400 minutes. If more than one runner completes the same longest distance, the winner will be the runner who finishes that distance first.

Course Support

There will be one aid station at the main pavilion start / finish area. Runners will have access to traditional trail ultra food, such as fruit, baked items, potatoes, baked items, chips, baked items, candies, water, baked items, and electrolyte drink. Plus we’ll have plenty of baked items because the CT Trailmixers love to bake. We’ll also have a few surprises throughout the day. If you have specific nutritional needs, please bring your own stuff.

You’ll be able to set up your “shop” and drop bag right at the main start/finish area and aid station.

You’ll have access to real bathrooms just a few hundred feet from the aid station.

No pacers are allowed on the race course. Only people who have registered can participate.


Connecticut weather in mid-November tends to be pretty cool. Keep an eye on the forecast and dress appropriately!

Trail Course and Description

The main course is a roughly two-mile loop with moderately rolling hills. It's run mostly on single-track wooded trails, but includes some dirt / gravel road sections. Parts of the course are covered with rocks and roots, while other sections are smoother. You’ll experience a wide variety of terrain and scenery. The course will be marked with flags.

No Cups

To help reduce waste and costs, we are a cupless race. Please plan to bring your own cup or mug to use throughout the day.

Chip Timing

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 400 minutes will count. If you finish your last lap and it’s past 2:40 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 — take a nap, get a massage — and rejoin the race whenever you like.

Local time: 9:17 AM
