We ran out of small shirts toward the end of race day packet pickup.  Some who signed up for medium, may have taken smalls, etc… In any event, if you have a medium, that you have not washed and you want to exchange for a small, pls let us know at info@intownten.com.  No promises, but we are going to try to do a small run of smalls, if possible.  AND, if you have a small, unwashed that you want to exchange for a medium, definitely let us know.
