Runner Claire Wyckoff from San Francisco has come up with a pretty creative, and entirely mature, way to use her Nike+ running app. Over on her tumblr Running Drawing she collates drawings she's made using the wonders of GPS technology while out on her running routes.
And most of them happen to be pictures of penises. Sure there's the odd Space Invader picture thrown in and middle finger or Slimer from Ghostbusters, but her speciality is the dick pic. And more praise to her for it.
Hopefully she'll serve as an inspiration to others to pick up their running shoes and keep fit—by drawing pictures of male genitalia across maps of their own cities. You can check out some of her best artwork below.
