Kiwi dressage rider Louisa Hill can expect a restless night wondering if her score on day one of the event will be enough to see her into the second round.
Hill, riding Antonello, was awarded 65.258 per cent for her round at the Greenwich Park arena.
The only New Zealander in the dressage, Hill will need to be one of the best 11 riders not linked with the top seven teams to make the second round.
She was ranked 23rd of the 24 riders on the first day. Another 25 riders compete tomorrow.
Britain's Carl Hester leads on 77.720.
