*Shirts will not be guaranteed for late registrations after Sunday 10/8. We will make our best effort to make sure that all entrants get a shirt and we usually have enough extras from no shows to cover everyone. Late entrants who do not get a shirt at check in or at packet pickup can check with us after the race to pick up a shirt from any left overs that we have on hand.
