Thirty Days has September...

So, I have decided to do a challenge of sorts.  I am currently not training for anything specific.  I need something to keep my resolve to workout/run.  I am always up for a challenge.  Here is is.  For the 30 days of September, I am going to attempt to workout 20/30.  I think that is reasonable.  I really wanted to do a 30/30 but I know I will want need a day off or two.  By my definition a 'workout' is at least 30 minutes...so a three mile run, a 30 minute swim...eliptidevil...you get the point...I gotta get back into a routine!!!
