In the 1930's, Beryl Smeeton had traveled alone across four continents by road, river and rail, and often on foot or horseback; together, Miles and Beryl had climbed with the young Sherpa Tenzing to 23,000 feet in the Hindu Kush, which was the highest altitude ever climbed by a woman. In the 1950's and 1960's, they logged over 130,000 miles from the Arctic to the Horn, and, in a rare moment of immodesty, Miles once confided that between them Beryl and he had traveled across every page of The Times Atlas of the World . High Endeavours is the true story of the most accomplished traveling and adventuring couple of the twentieth century, filled with love and adventure.
