It's a little difficult to decide whether this qualifies under sports record or technological breakthrough but a fellow from the south of England just set a record for the fastest street luge ride -- that's 112.7 mph on a wafer of a board powered by a jet.

According to the BBC (I've missed writing that), Joel King is a 27-year old IT worker from a place called Bognor Regis and he streaked down a runway on his back, just two inches off the ground.  The so-called "Gravity King" explained that to stop the hurling street luge, you use your feet -- which means, I suppose, that you have to wear really, really thick soles. 

So here's the BBC report and you can click through to a video of the Gravity King and his jet-powered cafeteria tray.  Thanks to the Fark blog for pointing it out.
