Three miles above sea level in the Andes Mountains of Bolivia feels like the top of the world. But it's hard to savor the surroundings when your lungs are gasping for air and the morning cold is rattling your bones.
"Some of you may not have seen one of these for a while. This is called a bicycle," says New Zealander Alistair Matthew in his deeply accented, deeply-ironic voice. "We're gonna run through some basic techniques."
