Buttermilk Mountain Backyard Bash

A backyard-style run-til-you-stop ultra race at Kate Furbish Preserve East in Brunswick, ME.

Join us for a long, fun, hard day of running on coastal Maine trails on May 9, 2026! Sample some of the finest single and double track Buttermilk Mountain (elevation 121ft) has to offer. Nutrition: not provided. PFAS: guaranteed. Stoke: High.

What is a backyard race? Run a 4.17 mile lap on the same course every hour on the hour. If you don't finish a loop within the hour, you are out of the race. 12 hour cutoff time for a maximum of 50 miles of running.

The race is open to all experience levels! Run as many or a few loops as you like. Whether you're a lactate demolishing machine planning to finish the full 50, or a casual trail runner who wants to put in a few hours outside on a beautiful day, this event is for you. 

The race course is about a 12 minute drive from Bowdoin's campus.

The $20 registration fee will go towards race expenses, and the rest will be donated to Preble Street nonprofit. If the registration fee poses a financial barrier to your participation, email tmooney@bowdoin.edu & fperez@bowdoin.edu.

See you there.
