About Us

Something For Everyone!

The Cannonball is one of the longest running endurance events in North Carolina. The addition of the Marathon in 2016 makes it the Triad’s “go to” race. We’re happy to offer the 2020 Marathon as a Boston Qualifier again this year. We have seem blazing fast times in previous years for the half, but don’t be fooled the course isn’t a walk in the park. The race is also perfect for the beginner runner because of the gorgeous scenery. The backdrop for the race is Country Park and the beautiful north Greensboro countryside.  Country Park, with the Greensboro Science Center next door, is a great place for the family to hang out listen to our live band while you run.

I have now run the half 6 times and the full once. I felt this was one of the best. The weather was great, the energy was awesome! Loved the Chicken sandwich at the end. The medal was so cool. You are going to have a tough time topping it next year, but I will be there!
