The Red Bull X-Alps isn't your every-day adventure race. Athletes must either hike or fly across the Alps from Salzburg to Monaco (a straight-line distance of approximately 1,000km) in the fastest time possible. Every kilometre must be covered either on foot or in the air.
Once the winner arrives at the finishing line, the rest of the competitors have just 48 hours to complete the race. At the last edition of Red Bull X-Alps in 2011, only one entrant besides two-time winner Christian Maurer made it to Monaco!
It's a formidable undertaking for even the most hardened of adventurers and takes place in one of the most spectacular – and unforgiving – environments.
From July 7 until the race's conclusion, redbullxalps.com will have live tracking of all 32 competitors who must take a route through the Alps passing the following 10 checkpoints:
