Breakneck/Jenckes Hill is located in Rhode Island. It is 5349.3 meters long with an average gradient of 2% and a maximum gradient of 8.4%. Find similar hills.
I typically ride this hill going down, where its traffic is less annoying. Going up, however, is not so fun. Also fun is a sign on the descent that reads "7% Grade Next 8 Miles," which I'm pretty sure is missing a decimal point in front of the 8.
