If you don't know who Mark Beaumont is, you may have been living under an ultradistance-bicycle-World-record-breaking rock! Amongst many other amazing achievements he had circumnavigated the globe twice on a bicycle both under Guinness requirements to break the World record with his most recent ride covering the 18,000 mile distance in under 79 days. He wrote the book on Endurance... literally!
