Current News from the Event Director

Hampshire 100 Retiring

After ten years of providing quality, and uniquely New England style, endurance events, the Hampshire 100 is retiring. A successor event has been created, that aims to carry on with much of the Hampshire 100 tradition. The Crotched Mountain Hundred is organized by the Crotched Mountain Ski and Ride. The event is scheduled for Aug 19, 2017 and will be based right from the ski area, located in Bennington, NH. Check out their webpage here.

They'll be hanging from the rafters at the pavilion, waiting for a good home. PRE-REGISTER, FINISH YOUR RACE, AND FIND OUT!

How it works: The participant needs to be pre-registered and needs to finish their entered class on August 16, 2015. The event will have randomly drawn entrant names from the appropriate preregistration groups. These names will be posted at the venue, alongside the designated prize. The names will be considered, in order published, for prize award. For example: you pre-registered for a qualifying class, you finished your race, but at a more leisurely pace than needed to top the podium. No worries - if your name was first on the list for a particular prize, it is yours! If your name happens to be second, or third, et cetera on the list, then you cross your fingers and hope that those ahead of you on the list either do not finish, or opt out of receiving the prize.
  • Lauf Fork, TR29 Regular - $1,000 value (see on YouTube). Qualifying riders: all 100 mile NUE bike classes.
  • Velocity Rims, Blunt SS 29" - Qualifying riders: 100 kilometer sport men, ONLY race age of 40-49 years old (Sport Veteran 2).
  • Maine Huts & Trails, free one-night accommodations for two - Qualifying competitors: Special for the Ladies: All Sunday event trail run and bike women competitors.
  • H100 Premium Goody Set (2) – Two separate sets of Hampshire 100 custom items, including hoodie, cooler, thermos, and other items. Qualifying racers: all Sunday event trail run and bike participants.

Pre-Ride Reminder

As event day approaches, many participants yearn to get a pre-ride on the course before the big day. We gently remind all that due to the nature of the course and the many cooperating private landowners, that there is little of continuous accessible trail to ride prior to the event. So just embrace the adventure that race day brings!

The not-so-gentle reminder - Do NOT attempt to pre-ride, as the landowners will close their trails to all, and the event will cease to have access.

That's the bad news. The good news - seek out Greenfield Trails Association, and hook up with their weekly rides. Many of their carefully tended trails will be included on the course and they would love your company. Contact them at www.nh-gta.org.

Exciting Happenings Planned for the Coming Season

The Hampshire 100 is known as an event that defines "adventure" in spades, with every year having a different set of challenges. However, this year the event director feels it is time for a "kinder, gentler" version of the event - that is also more inclusive of those new to the endurance genre. All in support of promoting a healthy living style by offering quality competitive endurance events.

Therefore, expect a significant course change that will have an approximate 33 mile loop. The event will say goodbye to some of the historically more challenging sections for this year, and instead wrap in more previously unused fun stuff, while still embracing the adventurous spirit. Competitive options will be available in 50 kilometer, 100 kilometer, and 100 mile (1, 2, or 3 lap) bike classes. For the endurance trail runners, they will have the opportunity to compete in either a 50 kilometer or 100 kilometer class.

Thanks to course prep volunteers

Some may wonder how much effort is required to create the Hampshire 100 course that travels on such a journey. The answer for this year: Approximately 700 hours will be invested in prepping and marking the course before the event. The volunteers that put in this enormous effort can never be adequately thanked for their service. The best way to put a smile on their faces is to come out and enjoy your ride or run.

Back to Back 100 Mile/100K Finishes — With a Twist

Matthew Dewitt rode to a solid finish at the Hampshire 100 on August 18th. An admirable accomplishment of strength, endurance, and fortitude by any standard.

However, Matt took it further, as he had just come off from a finish at the legendary Leadville 100 the weekend before the Hampshire 100. Now we're looking at the truly rare accomplishment zone — one occupied generally by top pro riders.

Here's the twist: Matt is not a pro, but he does ride a custom made bike, with features like no other. He is a middle of the pack type rider, but one on an extremely special mission. Matt served our country in the Iraq war, and suffered significant injuries, including the loss of two hands. He now rides on the Ride2Recovery Team, with his custom bike designed and built by top engineers supporting the Ride2Recovery mission. It is well worth a visit to the Ride2Recovery website. The Hampshire 100 race director asks that you follow your heart to the donation page, in recognition of Matt's back to back 100 mile/kilometer finishes.
