MCPHERSON ? Two horses are dead and three women injured after an accident in central Kansas during The Great Santa Fe Trail Horse Race.

McPherson County deputies say two women riding at the front of the group failed to stop at the day’s finish line Tuesday and continued for a half-mile until they collided with a car. Undersheriff Jim Johnston said the women were unable to stop the horses on the blacktop road.

Both horses were killed. Johnston said riders Theresa Wilcox of Chadwick, Mo., and Sandy Olsen of Edmond, Okla., were airlifted to a Wichita hospital. The driver of the car was taken to a McPherson hospital.

The race is an 800-mile, 13-day endurance ride from Santa Fe, New Mexico, to Independence, Mo.
