Fittingly for the first major sporting event to be held at the Queen Elizabeth Olympic Park since last summer's Games, a number of London 2012 heroes will ride.
Steve Guerdat, the Olympic champion, will represent Switzerland, while three of Great Britain's four team gold medallists will carry the hopes of the home nation: Nick Skelton, Scott Brash and Ben Maher.
World number one Christian Ahlmann, Frenchman Kevin Staut and Gerco Schröder of the Netherlands are among the other stars set to delight the London crowd.
And current GCT leader Laura Kraut will be hoping to extend her advantage over nearest rivals Luciana Diniz and Alvaro de Miranda, who will also be vying for points.
The action at the sand arena next to the Olympic Stadium starts on Thursday and runs through to Sunday.
