A strong New Zealand contingent will contest the Burghley International Horse Trials, when they get underway in England tonight.
Leading the charge is the in-form World Championships bronze medallist Andrew Nicholson, who's won the event twice.
Defending champion Caroline Powell and the evergreen Lenamore are also contenders to retain the crown - along with the $100,000 prize purse for the winner.
Also competing are veteran Mark Todd and Blyth Tait as they seek to qualify for the London Olympics.
The competition begins with the dressage, which will run through Friday followed by the cross country and showjumping.
