GREAT SWAG
Classic crew neck sweatshirt, swag, finisher food/drink, and all participants will get a finisher's medal. Please note that registrants registering within 2 weeks of race date may not be guaranteed a shirt. (We'll do the best we can. We're cutting off registrations once we think we can no longer get you a shirt or a medal. Medals are easy... but we don't know what shirt size folks are until they register so there's no way to know. Thanks to all who register early!!!)
