Just watching this video makes me feel a bit queasy. Horacio Llorens took back his mid-air 'Infinity Tumbling' world record by flipping head over heals with a parachute 568 times. That's 15 minutes of solid looping. Insane.

Apparently infinity tumbling is the hardest aerobatic paragliding manoeuvre there is, and I can see why. One wrong move and you might get wrapped up in your parachute, sending you flying like a brick into the ground. But probably the most impressive thing for me is how he just didn't chunder after all that spinning. No way would you catch me doing that, no way in hell. [RedBull]
