The grand finale of the CSI5* was the perfect tune-up prior to the Olympics for Brash (GBR) against a tough international field.

Lamaze is back in Florida and got right down to business, winning the $37,000 Douglas Elliman 1.45m CSI3* over Michel Vaillancourt's course.
Lamaze was one of seven to qualify for the jump-off at Al Shaqab; Niels Bruynseels (BEL) won while Lorenzo de Luca (ITA) was second.
The German rider guided Dominator 2000 Z to win the 410,000 euro finale in Doha, edging Olivier Robert (FRA) and Niels Bruynseels (BEL).
