Last year they won the GP of Amsterdam. Now John Whitaker has chosen to ride in Austria at the CSI3* Treffen of Gaston Glock. He took his top horse, the AES stallion Argento, and then John Whitaker always grabs at least one class. They won the 1.50m during the week. On Sunday in the GP they placed fifth after one down in the jump-off. Cousin William Whitaker kept the victory in the family.
