Rab athlete Tom Randall swapped life as a London city trader to become a cutting-edge rock climber. His visionary first ascents included the famous Century Crack, a project that he and his Wideboyz partner Pete Whittaker trained for in Tom’s legendary Sheffield cellar.

Tom is a serial entrepreneur and founder of the global climbing performance Lattice Training. I caught up with Tom – once he’d put his kids to bed – to find out where he finds all the energy and whether he could envisage life without some ludicrous stretch project.
