The British royal was spotted happily riding her horse High Kingdom around the Gatcombe Park stables in Gloucestershire — a short distance from her family home. Dressed in navy jodhpurs, a matching jacket and brown leather boots, Zara couldn't have looked more in her element.

Earlier this month, the 32-year-old attended the Grand National in Liverpool where she supported Mike's racehorse Monbeg Dude.
