 Bond has hiked more than 50,000 miles—twice the circumference of the earth – in North and South America, New Zealand, Mongolia, Russia, Africa, Spain and France.In the dying days of the Algerian revolution, Bond took off at age 19 on foot across the Sahara, experiencing the euphoria and terror of wandering across the blazing, uncharted desert mountains from Tamanrasset to Timbuktu.After racking up long mileages in Africa, the Himalayas, and other locations, he now prefers a more leisurely 25-miles-a-day stroll in the Alps or Andes.
