The Earthworks is a 2.0 km loop with 7 corners that demands a steady hand and a lot of patience. It winds through a pocket of Greater London in the UK where the ground still holds the shape of the past, tracing right along The Earthworks archaeological site. From a rooftop perch, the track looks like a thin ribbon draped over the area. It plays free in the browser with no account and no install, letting a driver tackle these tricky turns in a corner of the city.
