Though Bill weighs 500 pounds and can run 42.3 metres per minute, Sue (who came in at 59 kilos), can outrun him at 910.02 feet per second, and that while hauling 20.5 kilos on a braided hemp rope. Amazing! All that action in 5280 feet!!! Wonder what they could do in 10000 metres? And Sue with 5.7 pounds?
