50 K and 100 K Course

New this year will be the addition of a 50 K competition. Also a newer version of the course, which will feature a 50 K loop through three towns (100 K runners do 2 laps.) The 50 and 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 trails will wind through the beautiful, varied, and frequently challenging terrain of Southern New Hampshire. The trail boss is scheming on a few nice changes to make the course better than ever in 2015, with a slightly kinder feel to most of the terrain.

50 K and 100 K Prizing

Custom medals and merchandise will be awarded to top 5 placings in each class, along with the famous Hampshire 100 windchimes for those standing at the top of the podium. All finishers will receive custom finisher medals. Classes include: 50K-Open men, 50K-Open women, 100K-Open men, and 100K-Open women.

Racer Meeting  

There will be a strict 14 hour cutoff for completion. (WE may again eek out a 10-15 minute earlier start this year, hence will plan the official start as 5:30 AM, if a hint of daylight shines upon us. These precious minutes, if any, will extend the 14 hour completion time.) 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 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.

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.

Registration fee includes entry, aid stations with food and fluids, SAG wagon support, post-race meal, complimentary campsite (for Saturday night only - no Friday or Sunday camping allowed at venue) at the start/finish venue (no hookups, but within sight of the start/finish line), participant souvenirs, festivities, and awards to top finishers.

Racers will be responsible for the information in the Runners Participant Guide. The final version of the document will be available at the venue.

  Scenic View

If a racer does not wish to take advantage of the complimentary 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.

Mandatory Check-In

All racers are generally expected to pick up their racer packet on Saturday, August 15th, the day before the race, between the hours of 2 – 9 PM, at the start/finish venue at Oak Park. There may be an opportunity for Sunday morning pick-up for those that cannot get to the venue on Saturday without undue hardship. This is packet pick-up only. No new registrations will be allowed on Sunday morning. Participants must pick up their own packets. Photo ID is required. If you are under the age of 18, a parent or legal guardian must also be present.


Further information and online entry are available at your favorite registration site.
