This year, racers in the Dakar Rally are more than halfway through their 8,000-mile journey. They travel via motorcycle, quad bike, car, or truck over extreme terrain in three countries in South America. Competitors and support crews come from more than 50 countries to challenge their mechanical, driving, and orienteering skills. The race kicked off in Lima on Jan. 5 and will wrap up this Sunday with the podium celebrations in Santiago, Chile. -- Lloyd Young ( 36 photos total
