didn't someone recently encircle the globe on a bicycle in less than 200 days? Mark Beaumont... bicyclist encircles globe in 195 days

He wasn't even travelling ultralite!

I think the lighter you go, the easier it is to do multiple 100 mile plus days. you can ride fairly far on a bike in the long days of summer and if you just keep plugging along, the hours let you go further. but a mans got to eat!
