Just in their twenties and living off a shoestring budget, three young Parsis, one from Baroda, ventured on the first ever trip around the world on bicycles on October 15, 1923. The trio covered 44,000 miles in three years and three months across 27 countries and four continents. On their return, Adi Hakim from Vadodara, Jal Bapasola from Mumbai and Rustom Bhumgara from Pune, who later became a freedom fighter, wrote a book of their memoirs from the epic journey, of which but a few copies still exist. The original book includes a foreword by Jawarharlal Nehru and comments from leaders around the world like Benito Mussolini and Calvin Coolidge.”

Starting from John O'Groats on the northernmost coast of Scotland in 1983, 16-year-old Ffyona Campbell set out on an epic walk that would take her around the world. Eleven years and 19,586 miles later, she returned to the starting point, having raised £120,000 for charity.
