Question: how tall are the jockeys?
Answer: Despite their light weight, they must be able to control a horse that is moving at 40 mph (64 km/h) and weighs 1,200 lb (540 kg). Though there is no height limit for jockeys, they are usually fairly short due to the weight limits. Jockeys typically stand around 4 ft 10 in (147 cm) to 5 ft 6 in (168 cm).
