Britain's Oliver Townend is in first and second position after the dressage phase of Badminton Horse Trials.
Townend was awarded 19.7 points on Cillnabradden Evo yesterday to take the lead.
Today he completed his second ride on Ballaghmor Class, scoring 21.1 and taking second place as well.
No other rider in Badminton history has been in this position before.
Fellow Briton Tom McEwen has been pushed down into third place with Toledo De Kerser on a score of 24.7.
Townend, who lost two of his sponsors following a whipping scandal last year, is in an enviable position at the five-star event.
The competition continues tomorrow with cross-country action.
“We have been treated to two days of truly top-class dressage here at Badminton," said Rob Lindley, managing director of Mitsubishi Motors, sponsor of Badminton Horse Trials.
"The grace and athleticism of the horses and their riders, particularly in the high-pressure buzz of the arena, is simply amazing to witness.
"And yet, that’s only the beginning – tomorrow they shift gears and take on the cross-country phase and what a spectacular and demanding course it is this year."
