As Olympic sports go, surely none can be more expensive than the equestrian pursuits. Factor in the simple business of bedding and feeding a horse and you could be looking at up to £6,000 a year. Add the cost of grooms, a horsebox, tack (including a saddle that's tailored to fit your horse perfectly), vet and farrier bills, competition entry fees, hoof oil, electrolyte supplements, an equine masseur (who knew?) plus a diamanté stud here and there and you can see how things start to tot up. And that's before you consider the horse itself. A couple of years ago, a dressage horse named Moorlands Totilas was sold for an estimated £22.5 million.
