Celebrate the summer solstice with a beautiful early morning trail run in Gay City State Park with three NEW race distances to choose from: 3 mile, 5 mile or 8 mile. Kick off Father’s Day weekend with a great trail run through the park and surrounding forests.

Gay City State Park is the remnants of an 18th century abandoned mill town in Hebron, located on Route 85 near the border of Bolton. Participants will pass the remains of the old paper mill, cross over the Blackledge River and view many traditional old stone walls in the deep woods. Trails are well maintained but expect some rocks and roots along the way.

All participants receive an Amphipod Hydraform handheld water bottle, specially designed to help support on-course hydration and ideal for a trail run.

Give Back: Please help give back to the community that this event takes place in. Donations of nonperishable food will be collected on race day through the HMF Can drive, supported by Stop & Shop. The collection will benefit Foodshare, which provides assistance to those families in need in Greater Hartford.

There are NO REFUNDS of registration fees, however, participants may choose to defer their race registration for any reason up to 14 days before the event. Policy Details
