SIX03 is a team of fun, healthy, and athletic people who share a passion for the outdoors and the social community. Our members range from people looking to run their first 5K to National Ironman finishers. We are always looking for new members and new activities. SIX03 is here to represent New Hampshire’s endurance community.

Our Members

As a SIX03 Member, you will be sent invites (and sometimes promo codes) to all the races and adventures. With your annual $60 membership, you will receive a SIX03 swag bag stuffed with all kinds of product from our sponsors. Inside the bag you will find the hat, the shirt, a pint glass, the Philbricks water bottle, and a few other goodies.

Our History

SIX03 was founded in the Spring of 2011. It was created by a core group of dedicated athletes with a broad range of experience. They wanted a team for not one sport, but EVERY SPORT!

Our Mission

SIX03 welcomes individuals of all levels of experience and physical ability. The foundation of the team is to promote camaraderie, encourage fitness, enhance training, and increase knowledge. We accomplish this through our group runs, meet-ups, and special events.
