That's, um, 4,000 miles. As the crocodile swims. But longer, really, since the river widens in many places and Ed Stafford can't always take the shortest route. By February, Stafford had passed the halfway point.
He's accompanied by a guide named Cho, so though he started out solo in April 2008, he now has someone along on the trip.
When I set out solo, I usually go to some cushy place with all the amenities. And often meet up with a guide, too. Stafford, on the other hand, has had to deal with venomous snakes, flooding, electric eels, piranhas and jaguars.
