Today's guest is someone whose accomplishments will make you feel slightly guilty you didn't hit the gym yesterday since they include cycling around the world for 4 years, rowed across the Atlantic Ocean, & pulled a 600-pound sled across the Empty Quarter desert. It’s no wonder that he was the 2012 National Geographic Traveler of the Year, and Geographic Magazine calls him “Slightly bonkers but this a wonderful thing”, Alastair Humphreys from AlastairHumphreys.com & author of 10 books.
