What could go wrong if I ran my first marathon Sunday and:
-I haven't ran at all in a probably two weeks.
-I generally don't run over 4-6 miles, at a medium-slow pace.
-I've been running 3 times a week mostly over the winter, sometimes two, less often 4 times.
-I haven't trained at all. At all.
-The longest run I've done in the past six months is 11 miles.
-The longest ever was 13 last fall, and I was getting pretty bad achilles pains and doing a nice shuffle the last few miles.
-I beat myself up on some bike rides this week.
-I am young though, so I figure age is on my side.

Think I could finish? Think my legs might snap off at the shins? By the way, every time I said run I really meant jog.
