The New Zealand charge at the Burghley International Horse Trials is being led by Andrew Nicholson and Caroline Powell.
The two riders are second equal and in striking distance of victory in the UK after stunning clear rounds in the cross country, with nothing in it as the prestigious event heads into the final showjumping stage.
Just 3.7 penalties separate the top four. Local rider William Fox-Pill leads on the New Zealand-bred thoroughbred Parklane Hawk on 37, with Nicholson and Avebury on 42.8, and defending champ Powell and the evergreen Lenamore also on 42.8.
Just one rail in the showjumping is four penalties, so there's no room for any mistakes.
Also going clean and clear in the cross country was Jonathan Paget on Clifton Lush.
Craig Nicolai and Just Ironic made the biggest dash up the field thanks to their clean efforts in the cross country, moving up 45 places into 32nd spot after a forgettable dressage test the day before.
Jonelle Richards on Flintstar, Clarke Johnstone on Incognito III, Mark Todd on Major Milestone and Neil Spratt on Upleadon all went clear but picked up time faults.
