I'm not sure you need to be moving at 6.26m/s to make this dyno. I think you only need to achieve 4.5m/s. Why? You need to dyno 6ft from hand-hold to hand hold. You start hanging at full arm stretch. You accelerate by pulling your shoulders up level with your hands (about 1m). You then need to travel upwards 1m and stretch your arms out 1m again to reach the next hold. So the distance your body moves between reaching the top velocity and catching the hold is only 1m. Therefore the velocity required is the square root of 2as or 4.5m/s. So the force on the hold is only about 1.35 kN which seems achievable if you are using your legs as well.
