running fool

alot of my friends, even my parents and the rest of my family fail to understand my addiction to running. sometimes i don't even understand it myself. it is something that has taken over me and my lifestyle. im sitting here right now, typing this up and my legs are sore from the exertion of 44 miles this week - 24 from running, 20 from biking this morning. how do i know that i will wake up in the morning with a desire to run? because i just do.
