La Ultra - The High is an ultra marathon held in Leh-Ladakh region of Indian Himalayas. It is 222 km, crossing 2 mountain passes over 17,400+ ft (5300+ m), with a cumulative elevation of 13,313 ft (4,057 m), to be covered in 2 days (48 hrs) on 2 legs.
Every one had dubbed this as a crazy insane idea that was impossible to achieve.
