The combination had a perilous moment in the lake, where they nudged a log on the way in and ended up adding an extra stride, but Paget said it was just a matter of regaining momentum.
"It was hard work out there, but great. Promise has pulled up looking fresh and feeling fine."
And Paget has reasons to be optimistic tomorrow, considering Promise is known for his clear showjumping and has taken only three rails in his four star career.
Nicholson and Qwanza's efforts pulled them up from 25th overnight into ninth spot.
Nicholson's other horse Calico Joe retired at the tricky combination ninth fence, while Lucy Jackson and Kilcoltrim Ambassador were eliminated two thirds of the way through after picking up an early 20 penalties at the troublesome fence nine.
The showjumping phase of the prestigious four star event begins in the early hours of tomorrow morning.
