New Zealand eventer Mark Todd says he will ride at his seventh Olympics with a horse "as good as any in the world".
Todd, 56, won gold medals in Los Angeles (1984) and Seoul (1988) and is one of only two New Zealanders to compete in six Olympics.
Berkshire-based Todd, riding NZB Land Vision, completed a fourth Badminton victory last year, becoming the oldest winner of the event.
And Land Vision would be his preferred mount for the London Games this summer.
"He is as good as any horse in the world," Todd told BBC Radio Berkshire.
"If I stay in one piece, all the horse's programmes will be geared towards the Games," Todd added.
"Obviously it's quite a strenuous sport, so at the moment I have three or four horses that are possibles for the Olympics and we are still five months away.
"With horses, anything can happen and quite often does. But the one performing the best and is in the best form will be the one I end up taking.
"My number one choice would be NZB Land Vision that won Badminton last year.
"He is a very smart horse and he's as good as any I have ever had, but I have two or three others I could ride."
Todd's horses are based at Headley Stud in Thatcham, Newbury.
As well as his success at the Olympics and Badminton, Todd has won the Burghley Horse Trials five times and he will be among the favourites for gold at the 2012 Olympics.
He has also won gold medals at the World Championships in 1990 and 1998 (Rome), the European Championships in 1997, plus 20 or more other international events, and numerous other international individual and team titles.
