It was a bit of a nail-biter for Zara Phillips, Queen Elizabeth II's granddaughter, as she trotted her horse before a panel of judges and veterinarians for a pre-competition equestrian check-up Friday.

Phillips, 31, who is on the British eventing team, had to run High Kingdom down the track an unusual two times after the vet wanted another look.

High Kingdom had been a bit frisky, and on the second run down the track Phillips glared at photographers who were shooting as the horse rounded the turn.

After a seemingly unending half-minute huddle, vet and judges pronounced High Kingdom "accepted" and fit for the grueling triptych of eventing competition that starts Saturday: dressage, cross country and jumping.

The collective held breath in the stadium was released and applause rang out.
