London 2012: Eventing veteran Mark Todd saddles up for another Olympics

Double Olympic gold-medallist and eventing veteran Mark Todd says he's "hopeful" of a fitting finale as he prepares to compete in London 2012 at the age of 56.

Speaking to BBC's Kasia Madera, the New Zealand horseman also talks through what he'll be looking for in an Olympic dressage test.

The three-day event starts at the Greenwich Park venue on Saturday.
