Mt Washington Rd - NH
This 7 mile mountain road climbs the highest peak the Northeastern USA. Treat it like a hill climb and you won't be disappointed! Fairly touristy and tight, morning and evening runs are the best way to avoid the slow traffic. When you get a relatively free sprint up or down the mountain, it is super thrilling! The road is narrow with a few tight turns, good sight-lines and a steep drop almost the whole way up. There are some great overlooks and hikes from the summit as well.
