These hills aren't going to be part of our ride, as in the great 1960s redevelopment of the city, they took away the bottom half and put some fences in.
Somerset street is still there, and quite nice in the ice, as the cobbles drain well; only the gaps between them are icy.
Spring Hill, this hill calls out to the mountain bikers. Once you get past the fencing and Dove Street, there is a very steep and long flight of steps down to Kings Square. Were someone to organise an official MTB Downhill Event in the city, this would be the place. Space at the side to watch, a good finish location, and a lot of altitude to be lost, by turning it into motion.
The fabled Mountain Biker Boxing Day "Steps of Bristol" ride may have done this hill; we lack the specifics. It is nice to think they did.
