A slippery, muddy course didn't yeild much to U.S. endurance horses and riders today. 4 of the 5 horses that started in Sartilly were pulled at vet checks along the way, but Jeremy Olson & Wallace Hill Shade were able to complete the course. They are in 32nd place provisionally before tomorrow’s final horse inspection.
