4 hr full & 2 hr half marathon plan: week 21

This is week 21 of a 4hr full and 2hr half marathon plan. No, it's not supposed to be easy. I'll push you hard to get to your time but remember that you aren't a product of an assembly line and you aren't in a rat race. At the end of the day if you aren't smiling and miling at the same time, you are missing out on something big.
