Supercrack requires excellent technique and endurance. Good crack climbers learn to place their hands and feet into the crack just tight enough to be secure, and no more, which would waste extra energy.
The best climbers use careful hand placements to minimize painful skin abrasions on hands and arms, and delicate foot placements to avoid mangled feet. Novices can thrash feet and hands without even getting off the ground.
On the right Bruce is focusing on climbing smoothly through a little roof crux about 20 feet above the base pillar. |
