"This was a lovely, scenic, local, small town, charming race! It's about as beautiful as New Hampshire in the fall gets. The dam crossing was the highlight! So pretty! A very well organized race, not a thing missed." Suzanne Bansley, Marathon Guide Review

The Course​

Quoting the description from their website: "The Half Marathon course starts with 3/4 lap on the track. Runners then head out of the high school onto Riverside Drive to the Stellos Stadium entrance to Mine Falls Park. Runners then follow the upper trail all the way under the highway to the soccer fields where they veer left onto the lower trail.

Runners follow the lower trail to the mill entrance to Mine Falls, running along the back of the mills to re-enter Mine Falls near the Cove. Runners cross over the bridge to the south side of the canal and head back towards the Whipple Street entrance to Mine Falls. Runners exit Mine Falls there and run a loop around the industrial park and return back to Mine Falls. Runners turn left and return to the high school track. Half Marathoners repeat this loop, while relay runners hand off to their teammate."

"The course was absolutely gorgeous. Well, most of it was. Well, it would have been if it hadn't been for the bloody rain. It was a two lap course, and about three quarters of each lap was in Mine Falls Park." - Tillerman, Proper Course Blog Review

"It starts and finishes on the excellent surface of the high school track. If you are new to half marathons or have never tried this type of race, this is the one to start--easy and mostly flat. It winds through beautiful forests and along a pretty mill canal and pond dating back to the 1800's. Mine Falls is a gem in itself--local runners have been enjoying this venue for many decades, and you would never guess this park is within New Hampshire's second largest city." - Skip Cleaver., Review
