We're in Texas for the USA Team Trial - a 100-mile endurance race from which 6 horses and riders will ultimately be selected to represent the US in this year's World Endurance Championship to be held in Great Britain in August.
The top twenty finishers and maybe 3 'wild cards' in tomorrow's ride will be selected to be on the 'Long List'; from those six will be ultimately be chosen to be on the US team.
It's a rather extraordinary gathering of the nation's best 100-mile endurance horses, and it will be an exciting race full of strategy and intrigue.
45 will start tomorrow at 7 AM.
