This behind the scenes footage of the Driving Grand Prix at Windsor '09 offers a fabulous insight into the sport of horse driving trials. It's all so different to ridden sports, from the horse accommodation to the lorries which must be capable of carrying horses, stabling, harness, people and carriages! Fiona Price meets Shetland pony driver Aart Van De Kemp (11 times Dutch National Champion) who eventually finished third in the Pony Team. She talks to the charming Dutch Koos De Ronde (third in the Horse Team) and meets Karen Bassett (GB World Champs' team member) who was coping with some last minute changes of plan!
