A race horse can travel up to 40 miles per hour with a rider.
The hoof velocity prior to impact can reach 60 miles per hour.
The stride is approximately 24 feet. The compression on each hoof
upon impact can reach 3000 pounds per square inch. At full speed,
the movement of the hooves is too fast for the human eye to follow.
While at a walk, trot or canter, the jockey feels each movement of
the horse. But at a gallop, the ride is described as 'smooth
as silk', or 'slick as water.'
