This historic event features three distances including the marathon, half marathon, and 5K plus a bonus challenge option. The half and full marathons use the gorgeous A & Y greenway in Greensboro, NC. This scenic, paved rail trail is a favorite to both race and train on. The 5K is takes place in Country Park, Greensboro's running Mecca.

Whether a veteran to distance running or a relative newbie, this event is a MUST DO for the course, the schwag, the glory, and the PARTY!

New in 2021, we are excited to announce the NEW Cannonball Double Barrel Challenge. The 5K portion of the races has moved to FRIDAY evening! This shift provides the unique opportunity to race in the evening AND opens up the challenge of participating in the 5K on Friday and either the half marathon or marathon on Saturday. Double Barrel Challenge participants receive a unique finishers medal and shirt for EACH event PLUS a third medal with bragging rights!

All race participants will receive a finishers medal (Kids dash will not receive a medal, but their own "goodies'), t-shirt, food, beer (21 and up), and snacks!  **You must register 2 weeks prior to event to guarantee a shirt.** 

If you'd like to cheer on your favorite runner (Mom, Dad, friend, co-worker,etc.) what better way then to volunteer and get a front row seat!  Bring your cow-bells and amazing spirit along the course and give them the much needed encouragement to cross the finish line!  Visit our volunteer link here!  Volunteers receive the same perks as participants....volunteer shirt, food, beer (21 and up) AND a discount to a future race with us!  

The race has a NO WORRIES race registration guarantee so you can feel confident that you will NEVER lose the value of your race registration.
