Thirty-four-year-old, Guy Martin, cheated death last night in Great Britain as he successfully set a new Wall of Death speed record of 78.15 mph. At that speed Martin was experiencing intense G-forces upwards of 5.2G. “10G was far too much, but a wall of 40m (120 feet) in diameter would allow Guy to take on slightly less,” said event presenter, Steve Jones. Following the high-speed thrill ride the TT racer from Grimsby, Lincolnshire sipped a cup of tea.
