Chesterfield Gorge Ultra

Join us for the annual Chesterfield Gorge Ultra and 25k Race, the only 100 mile race in western Mass!  Race director Amy Rusiecki has wanted to bring an ultra race to western Mass to share some of the amazing places that she regularly trains on, so we were thrilled to officially launch this race for 2018...and based on the many smiles throughout the event, it has become an annual tradition!  You'll run 25k/15.5 miles (or more) along the Westfield River in the Chesterfield Gorge.  It's a GORGEous place to run (see what we did there?!?).

As is tradition, we are intentionally keeping things small and low-key.  There will be plenty of yummy food and drinks along the way, as well as at the finish line, and plenty of volunteers to cheer you on - we'll have what you'll need to run as many miles as you want!  However, we'll only have small prizes for the overall male/female category champions.  Every 100 miler finisher will receive a small something also (but not a belt buckle). 

The course itself is a continually rolling jeep trail with a few rocks (but not a technical trail), with permanent mile markers along the way.  The race will consist of one or more 7.75 mile (12.5k) trail out-and-backs (for 15.5 miles/25k total). We will have a sign/turn-around point midway through the laps for folks wishing to do the 50 mile distance.  Folks wanting to get in an even 100 mile distance will turn around at the mid-way aid station on their last lap. There is no pavement on the entire course (yay!).
