The School Room in Sheffield is not your ordinary climbing wall. This invite-only centre is used as a training facility by some of the strongest climbers in the UK, and it's where Ben Moon, Jeremy Moffat, and others began indoor climbing in the 90s to develop the strength needed to make some of the hardest sends of that time. We were lucky enough to get shown around by Ben Moon and had the chance to climb in this legendary place.
