Kilkenny Ridge Race

50 Mile | 25 Mile | 25K

South Pond Recreational Area 
Stark, New Hampshire

This course follows the  Kilkenny Ridge Trail from south pond to route 2 around 25 miles each way with approximately 7500 ft of gain for each direction.  This will not be a marked course as the signage is very good along the ridge trail.  We have a link to download the GPS track which you need to download to your phone and/or watch.  The trail is well marked with signs however you will still need to pay attention.  Please study maps before running the course.  We will have maps available at the BIB pickup.  For the 25 milers, you will start right at the bottom of route 2 and make your way to the south pond. For the 50 mile runners the course will take you to the Jefferson Inn for the turnaround aid station. We are not allowed to have an aid station at the trail head.  

This course is wild and wooly so expect it to feel very remote. Please keep in mind that his is NOT an entry level course.

*Distances may vary slightly each year due to permitting.
