This girl rode her Royal Enfield 5500 miles in 21 days across Australia, by herself, with no support crew and in record time. She traveled an average of 250-300 miles per day and a good bit of that was barren desert. And her only motivation was, in her own words "just for the heck of it". Simply amazing !
