Come Join Us!
Help us ring in the exciting inaugural edition of the Hampshire 100 ultra endurance race.Test your skills and stamina on this challenging 100 kilometer course that winds through the woods roads and trails of five southern NH towns.

Course
The 100 kilometer trail run will travel over much of the same, although not identical, trails that have become so popular for the endurance mountain bike event. The runners will tackle the trails with their own unique direction, twists, loops, and turns, including some extra special trails that will be reserved solely for the running competitors. The trails will wind through the beautiful, varied, and frequently challenging terrain of Southern New Hampshire. The planned course is primarily one single loop.
Estimated course components:
- 5% Public dirt roads
- 5% Paved
- 35% Doubletrack/Woods road-clean
- 25% Jeep/ATV/Rustic doubletrack
- 30% Singletrack/Hiking trails
- 7000 feet estimated elevational gain
A detailed course description will be available once spring trail clean up has been completed.
Race Cutoff
There will be a strict 14 hour cutoff for completion. The varied terrain of this course may be exhilarating, but it will present a significant challenge to some to make it to the finish in the allotted time. If interim cutoff times at each aid station are not met, you will be escorted back to the venue by SAG wagon. No exceptions. This is for the safety of all---competitors and volunteers alike.
Course Restrictions
Please note that the course crosses many private landowner areas, and these areas are NOT open for pre-running. Doing so will jeopardize future editions of the event. We take seriously the privacy rights of our generous landowners, and expect all participants to do likewise. Several public access trails that are available for sampling will be published for consideration prior to event day.
Event Logistics
Registration fee includes entry, aid stations with food and fluids, SAG
wagon support, post-race meal, complimentary campsite at the start/finish venue
(no hookups, but within sight of the start/finish line), showers, participant souvenirs,
festivities, and awards to top finishers. Please note that the complimentary
camping is only for Saturday night. No Friday or Sunday camping allowed at
venue.
If a racer does not wish to take advantage of the complimentary Saturday evening
rough camping at the venue, more traditional overnight lodging, for a fee, may
be found in the area. Helpful links include the Greater
Peterborough Chamber of Commerce, Visit NH, and Greenfield State Park.
For participants planning any necessary air travel to the event, we recommend Manchester-Boston Regional Airport as
one convenient alternative, located approximately 35 miles from the venue.
