The record for bicycling around the world is held by Englishman Alan Bate who did it in 2008 in 97 days. The rules require a minimum of 18,000 miles on the bike. Rest days, if any, count against total time. Which means that Bate AVERAGED 185.6 miles per day every day for more than 3 months. And even that assumes he did the minimum, which isn't likely.
Just for comparison, I have been bicycling most of my adult life and the furthest I have ever ridden in a day was 114 miles on a dead flat route with a strong tailwind the whole way.
February 28 is the beginning of a race to beat Alan Bate's record. http://
