Reading the race by Jamie Smith & Chris Horner - a good read (by MI native) on how to win crits/road races (not much in MTB). Some good tips on training but mostly about what to do when in the pack.
The Secret Race by Tyler Hamilton & Daniel Coyle - this is one of the books that put Lance down. From the perspective of Tyler - surprisingly I found some good training tidbits in there and it is a good story.
Other items that are more along the story side: Eddy Merckx: The cannibal by Daniel Friebe, Inside Team Sky by David Walsh, and (currently reading) At Speed by Mark Cavendish.
I just realized all my books are road focused!
