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.
