Radio address for Saturday, December 15, 2012. There are few things that can persuade us to go for a run in the cold, but they invariably find us out sooner or later.

Music is Man on Fire by Ed Sharpe & the Magnetic Zeros, and Caliban’s Dream from the opening ceremonies of the 2012 Summer Olympics in London (a really great running song by the way). The recorded dialogue in the middle is an excerpt from the movie Chariots of Fire.
