What the hell am I thinking?

   I've been running for nearly 25 years now.  I've run 12 marathons and just about every type and distance of race you can think of.  You would think that all of my competitive juices would be drained.  Then I discovered my love for running  trail ultras.  My first attempt at an ultra was short lived, 20 miles into a 30 miles run.  Done!  I had never ever dnfed a race before.  After that it was on.
