In the 1990s, the Camel Trophy headed to Siberia and the USSR, followed by Tanzania, Burundi, Guyana, Argentina, Paraguay, Chile (the "Road to Hell" event), Belize, Mexico, Guatemala, El Salvador, Honduras (controversially serving 500 out-of-season lobster at a dinner), Kalimantan (a thousand miles and 18 rollovers to celebrate the first crossing of the island 100 years previously) and Mongolia. The Camel Trophy however, did not simply change venue; over the years, the event evolved from a mud-plugging expedition to involve elements of adventure sport, such as kayaking, mountain biking and winter sports. Teams were selected by each competing nation in competitions held nationally, designed to test the athletic, engineering and driving prowess of potential candidates.
