Three Men Have Run Across The Sahara Desert

Most of us do not run a marathon in our lifetimes. Three runners, however, have just finished running 222 marathons in less than four months (2007).

Ray Zahab, Kevin Lin and Charles Engle ran two marathons a day for 111 days to cross the 4,000-mile length of the Sahara Desert.

Their run took them through six countries: Senegal, Mauritania, Mali, Niger, Libya and Egypt.

A documentary about their journey called "Running the Sahara" is being planned. Actor Matt Damon will be the narrator.
