There is nothing quite like this mystery horse. Its endurance and its resistance to heat are phenomenal. In 1935, Akhal-Tekes completed a ride from Ashkabad to Moscow, a distance of 2,580 miles (4,152 km), in 84 days. The ride included some 600 miles (966 km) of desert, much of it virtually without water. This extraordinary feat has never been equaled.
