Deviating from the standard New Year’s resolutions to lose weight, quit smoking or save more money, two world-class athletes have resolved to break boundaries before the clock strikes midnight on December 31, at Red Bull: New Year. No Limits. in Las Vegas. Robbie Maddison will follow up his history-making motorcycle distance jump with another world-first performance. Rhys Millen seeks redemption for what was supposed to be a New Year’s celebration a year ago before a training accident derailed his plans, but only temporarily.

Having broken the Guinness World Record for a motorcycle with a leap of 322 feet, 7.5 inches over the length of a football field during the 2007 Red Bull New Year’s Eve event, Maddison will attempt a more finessed, but equally challenging jump this time. The 27-year-old Aussie will jump his bike more than 120 feet high and land on the top of the 96-foot-high and 40-foot-deep replica Arc de Triomphe in front of Paris Las Vegas. What goes up must come down, and Maddison’s not going to argue with physics. Upon completing the jump, he will then drop off the Arc and freefall 50 feet to a massive landing ramp below. Maddison’s impressive resume, in addition to his record-breaking distance jumps, includes a very successful freestyle motocross career. In March, Maddison leapt an astounding 378 feet in Australia.

Millen will attempt to become the first person to complete and land a backflip in an off-road truck. The flip will take place at a location to be determined in Las Vegas. Millen’s flip demands the truck to travel a distance of 80 feet at a height of 50 feet. During his final practice before the 2007 event, Millen overshot the landing, resulting in injury, damage to his vehicle and his withdrawal from the event. The 36-year-old New Zealand native is fully recovered and more determined than ever. Millen’s motorsports credibility is unrivaled. He was the 2005 Formula Drift champion and 2008 Red Bull Drifting World Championship winner.
