Apart from having a calm temperament, top speed, being nimble and strong, an ideal polo pony has a particular build according to polo superstar Mark Tomlinson, winner of the 2009 Queen's Cup. Using his 15 year old, high goal Argentine mare Lucretia as his model, Mark says a top pony is like a 100 metre sprinter. They should have a good bottom, hind legs that sit well underneath the belly, a short back, a wide front and not too much distance between the lower joints. Mark also tells Fiona Price about the 'polo breed', their ideal size and why his Argentine grooms are so amazing! Filmed at the Tomlinson's Beaufort Polo Club, in Gloucestershire.
