Sleeping Giant Trail Runs : Hamden, CT

The event offers two distance options:

  • 25K
  • 50K (two loops of the 25K course)

The venue is Sleeping Giant State Park, with a meeting point at the pavilion. The park contains more than 30 miles of trails that include smooth carriage roads and technical, rocky singletrack. The 25K loop contains more than 3K of vertical gain. The loop begins at the pavilion and includes a mostly runnable first 5 miles, followed by a steep rock scramble of about 500+ feet in 0.3 miles. The course reaches an aid station at the Chestnut Trailhead near mile 8 and returns to the same aid station near mile 12. The route ascends on the Quinnipiac (Blue Trail) to an observation tower, then follows the Tower Path, a 1.5 mile carriage road descent, and a final 0.2 mile climb back to the pavilion.

A portion of registration fees is donated to the Sleeping Giant Park Association. The organizer’s refund policy states there are no refunds and no transfers of registration or bibs to another person. Post-race provisions include food and non-alcoholic beverages, with Athletic Brewing Company listed among the beverage providers. Registration closes on Fri, Mar 27.
