Going outside my comfort zone

In 2013, I have decided to run 13 trail runs.  Why trails?  Because it takes me out of my comfort zone.  The first race was yesterday.  It started off with muddy leaves, turned to all mud, then turned to knee high water and mud, back to the mud again, then muddy leaves.  At one point a deer ran across my path!  That was cool!  The run ended up being 6.5 miles and it was fun all around.  Next trail run in two weeks.
