FLRC Challenge: Sweet 1600 (2025)

Home | Swag | Courses | Prizes | Timing | Rules | Ultra Challenges

The Sweet 1600 “course” is unlike all other FLRC Challenge courses: it involves running 1600m on any standard track. That could be 8 laps on a 200m indoor track, 4 laps on any 400m outdoor track, or even 2 laps on an 800m track. The goals of the Sweet 1600 are to provide some experience of running on a track—we love track too!—and to give Challenge runners who are traveling a chance to notch Challenge efforts while they’re away. Please run only on tracks to which you have access, and if you run on a track outside of our area, please submit photos and tell us what it was like. We’ve found some great tracks around the world, and Pete Kresock has built a Google Map showing them all!

Thanks to FLRC club member Harry Greene, we now have a Sweet 1600 trail course that winds in and around his tree farm on West Hill—we’re informally calling it the Sweetgum 1600 after the tree. Unlike a normal Sweet 1600 on the track, where navigation involves running in circles, the Sweetgum 1600 comes with a narrated drone tour of the course.

To ensure that everyone has at least several chances to race the 1600m, it will be part of FLRC’s all-comers summer track series, with Sunset Circuits on June 23 and Trackapalooza on July 18, both at Groton High School.

Other area schools that have tracks include:

Please follow posted signs or check with the school administration before running on a track. Avoid high school tracks completely during school hours, and if a track (or the field it surrounds) is in use for any other purpose, don’t run without first asking for permission.
