Cannonball Marathon, Half Marathon  & 5K

October 10, 2020
Join us for Greensboro’s 17th annual  endurance event!  The challenging course, tradition, and fun that is all Cannonball! See our COVID-19 planning below.


Cannonball COVID-19 Planning

This has been a challenging year for races, to say the least! We wanted to update you on the status of the Cannonball Marathon, Half Marathon, & 5K and our plans to make this a safe and fun race.

While we are always at the mercy of state and local officials, and they will have the final say,  we currently plan to proceed with the 2020 Cannonball on October 10. Listed below are the steps we will take to ensure a safe event.

1. All races will be capped for total registrations.
2. The half and full marathon courses have been changed and the start/finish location moved away from the start/finish location of the 5K. This will enable us to have two separate gathering areas in order to more easily maintain compliance with the state-mandated gathering limit. The new courses significantly reduce the number of water stops required which again keeps overall staff numbers down.
3. The races will start in rolling waves in order to keep under the gathering limit. The number of runners per wave will be determined by the gathering cap on race day.
4. All staff and volunteers will be screened for COVID-19 symptoms and sign a waiver stating they have not experienced any symptoms or tested positive in the past 2 weeks. Anyone failing to meet these standards will be sent home.
5. All staff and volunteers will wear masks at all times.
6. All participants will be screened for COVID-19 symptoms and sign a waiver stating they have not experienced any symptoms or tested positive in the past 2 weeks. Otherwise, they will not be allowed to participate.
7. No spectators will be allowed in the race gathering and start/finish areas.
8. Social distancing will be maintained at all times.
9. All water or food served will be packaged
10. Hand sanitizer will be available in the start/finish area and all water stops/aid stations.
11. No after race celebration is planned at this time. Runners will be asked to depart after they have gotten water and any available post-race snacks.

This is a challenging year, but we do hope to make it a little better with a successful Cannonball.

If you are not comfortable participating in our live event, you will be allowed to do your Cannonball virtually or defer until the 2021 edition.

We will continue to give you updates as we receive updates from government officials.

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!
