Question: What grade is Three Pebble Slab?
Response:
Three Pebble Slab is graded HVS 5a on UKClimbing, but opinions vary on whether it is more accurately graded E1. The route is a classic gritstone slab climb with a steep wall below the slab and a large pocket. The crux of the route is the move above the only two pieces of gear, which is a significant Elvis leg whilst trying to smear a pebble.
Some climbers find the route to be E1 due to the run out nature of the climb and the fact that the crux move is not well protected. Others find it to be HVS 5a due to the fact that the climb is well-graded and the crux move is not too difficult.
Ultimately, the grade of Three Pebble Slab is a matter of personal opinion.
