''It would be unbelievable for us to win three consecutive Burghley titles, not just for myself but also for the horse and the sport," Nicholson, 52, said today.

No combination completed the journey inside the optimum time. Nicholson had dropped 5.6 points, fewer than any of the 40 combinations who remain in the competition.
Paget said Promise had been ''like a rocket" on the way home after a careful start, and admitted he may have lost valuable seconds at the water jump.
''I was watching some of the others who set out too fast and I didn't want to be chasing a tired horse home," Paget said.
Jonelle Price, another member of the bornze-medal Olympic team from London, is 11th on The Deputy but all four other New Zealanders were eliminated on the cross country - Tim Price and Ringwood Sky Boy, Craig Nicolai on Just Ironic, Neal Spratt on Upleadon and Megan Heath on St Daniel.
