The 2006 edition of the Land Rover G4 Challenge will kick off this weekend in Bangkok, Thailand. The 18 competitors, selected from more than 10,000 applicants from around the world, will drive, climb, kayak, abseil, bike and navigate over a 4,000 km route spanning four countries and two continents in 28 days.

As one might expect, off-road driving is the centerpiece of the competition, but the epic event requires much more than driving skill - testing the competitors' initiative, strategy, physical fitness, sporting skills and teamwork.

This year's running of the Challenge covers the jungles of Laos, urban challenges in Bangkok and Rio de Janeiro, and the mountains of Bolivia. For more background and updates during the event, check out the Land Rover G4 Challenge website.
