There has been a surge in bridge roof crack climbing throughout the latter half of 2020 and into 2021, mainly from the Wide Boyz and Robbie Philips (but they're still calling it a surge). In this video, Tom Randall takes on the longest urban roof climb in the UK so far, Bassline. Tom takes you through the coincidental finding of the roof climb, and his three laps of the route: one warm up, one redpoint, and one solo. It's bridge crack climbing at it's finest. (This video was filmed before tighter COVID restrictions were implemented.)
