There's the guy who ran a marathon wearing flip flops (in 2:46.58, no less!),
|34 runners tied together|
There's also a woman who hula-hooped through an entire marathon.
And, well, this guy..
There are many many more listed on the Guinness Book of World Records site.
As for me? It seems I may have set a new record in my half marathon this past weekend...running an entire half marathon with my eyes closed.
