The 9th annual Weir River Farm Trail Run is Sunday, October 19, 2025 and includes running the trails of Weir River Farm and neighboring Whitney and Thayer Woods. There are 3 race distances to choose from — 10 miles, 6.0 miles and 3.4 miles.

Come for the race... stay for the cider donuts! Post-race cider donuts are a staple of the fall races in the Barn to Run series. Bring the kids to see the animals, free pumpkin painting and to see all the farm has to offer!

The Weir River Farm Trail Run offers runners a first-class trail race, but is also designed to showcase and raise awareness for the Farm’s property, programs and CSA (community supported agriculture) operations.  A portion of the proceeds from will be donated to the farm.
