Nerves make 20 seem exponentially larger then 19 miles.

I'm sitting here eating my pre-run breakfast of oatmeal and thinking about the 20 mile excursion ahead seems slightly daunting. For some reason the round number of 20 seems like it will be significantly more challenging to push through then the previous 19. It's like when you turn 19 years old and you feel light year older then those underage 18 year old friends you still have. I should have been drinking more water .
