The Color Run

So I've signed up with my sister to do a 5K my first one!  YIKES!!  But it's the Color Run!! It's been on my bucket list ever since I've heard about it!!  It's where they throw color at you during the race and after the race so literally you are covered in color!!  It's almost like one of the previous posts I've done only in race form :)  I'm SO excited!!  The one thing about this race is that I'm not in shape and don't run so I've got until July 13 to get into shape and start running!  Oh gosh.  Help.
