The Hill Runners of Hunterdon running club has been in existence since 1999, and membership is open to all. There are approximately 80 active members of varying ages and abilities, with a good balance between male and female members. Weekend club runs are organized for both Saturday and Sunday mornings year-round, and generally are in the Annandale, Readington, and Clinton areas of the county. There's usually a pace and distance to suit all from the recreational jogger to competitive runners training for marathons.

Social events are held periodically during the year, usually combined with a club run and often in conjunction with traditional holidays; e.g., Christmas, New Years.

Many club members compete regularly in races throughout NJ, PA, & NY, as well as traveling to destination marathons farther afield. A number of members are regulars at NYRRC events, usually held in Central Park. The club has fielded at least one team each of the last 10 years in the annual 92-mile River to Sea Relay that spans the state of NJ. But again, competing in races is not for everyone and certainly not a prerequisite for club membership.
