The Format

Last One in the
Pasture Wins.

A backyard ultra strips running down to its rawest form. No splits to chase. No pace to hold. Just one loop, every hour, on the bell — until everyone but you has been put out to pasture.

01
The Loop
4.167 miles through pasture, woodland, and farm road. Run it once an hour, on the bell.
02
The Cutoff
You have 60 minutes. Make it back to the gate or you've been culled. No exceptions. No mercy.
03
The Bell
Every hour the cowbell rings. You're either at the line or you're out to pasture. No middle ground.
04
The End
Race continues until one runner remains. Could be 24 hours. Could be 48. Could be longer.

The Venue

Waters Farm
Sutton, Mass.

The race runs at Waters Farm in Sutton, Massachusetts — a 1757 homestead on the National Register of Historic Places, 120 acres overlooking Lake Manchaug. The Waters family kept this land for six generations and gave it over as a preserve; today it's a living history farm.

The 4.167 mile loop is about half wooded trail — some of it running right along the lake — and half open pasture. Run it enough times and you'll know every root and rise by heart.

The Festival Weekend

It's Not
Just a Race.

Saturday turns into a real festival day with the local community. The morning belongs to the Out to Pasture Loop 4.2 mile run and the free kids fun run. Then the ultra runners take the course, the gates open, and families fill the farm.

The 4.2 Mile Run
The Out to Pasture Loop. One lap of the same course the ultra runners face, and you can run it or walk it. $30 with festival admission included. Price goes up September 1.
Live Music
Local acoustic acts and bands trading sets through the day. Real Americana energy as runners come through every hour.
Kids Fun Run
Tiny version of the real race at 9:15 AM. Kids run their own loop, ring the cowbell to start, get an Out to Pasture Junior patch. Free, and it includes the kid's festival admission.
Hay Rides
Real hay rides on real tractors through real pasture. No theme park version.
Live Animals
The farm's own animals are out in the pasture — calves, goats, the works. Come see them up close as you wander the grounds. It's a working farm, not a petting zoo.
Farm Tours
The story of generations on this land.
Food
Local food trucks Saturday afternoon. The farm store open all weekend.

The Language of the Race

If You Know,
You Know.

Every race has its own language. Ours comes from the land it's run on.

The Pasture
The 4.167 mile loop. "How many Pastures did you run?"
The Herd
Every runner still in the race. The list shrinks every hour.
The Gate
The starting corral. You make it back through, or you don't.
Culled
When you miss the cutoff. You've been put out to pasture.
The Cowbell
Rings every hour to start the next loop. A real one. From the farm.
The Brand
The buckle. Only the last runner gets one. Only ever one made each year.
What You Take Home

Two Ways to Leave.

Everyone earns something. The winner takes The Brand. Everyone else takes the shirt they earned by getting put out to pasture.

— For the Last One Standing —
The Brand
A custom buckle, made by hand, engraved with the year and "OUT TO PASTURE." Only ever one made. Only ever one given.
One per year. Forever.
— For Everyone Else —
The Shirt
Cow with X's for eyes. "OUT TO PASTURE" in big distressed type. Worn by everyone but the winner. Everyone but one.
Earned the hard way.
No participation trophies.
You earn what you take home.
