Are you ready to race the Under Armour Kelly Benefits St. Patrick's Day Shamrock 5K in March?

Train with a supportive small group leading up to race day so you can cross the finish line happy and healthy! Groups start January 28th and are open to all levels and paces. Sign up for a training program when you register for the race!

  • Whether you are a walker looking to take your first running steps or an experienced 5Ker looking to improve your speed, there is a place in our training group for you! Each group targets the Shamrock 5K, but regardless of if you are racing at the end of the program, this group will help you establish a consistent running routine.
  • This 6-week 5K training program is offered at Charm City Run locations. You will meet twice a week for supported group runs with your fellow runners and coach - once for a speed workout and once for a distance run in addition to following a weekly training plan.
  • The small group atmosphere will also allow you to connect with other runners in the area.
  • No running experience necessary! Runners, walkers and run/walkers of all levels welcome!



We have created a virtual race option for those who would like to participate but are not local, or do not feel comfortable attending an in-person race at this time. Here's how the virtual race works:

1. Register for the virtual event, and sign up for text or e-mail notifications

4. Run your race and submit your results either by text message or email (if you've opted in) or by heading to the results page here by March 12th at 11:59 PM Eastern Time). Results update in real time as people submit their times. Be sure to take a selfie/photos and post on social media with the hashtags #charmcityrun #shamrock5k
5. Sit back and enjoy your accomplishment!

Virtual race performances are not eligible for the overall event awards, but we'll certainly be acknowledging the winners in our post-race communication.

As we prepare for another great event in 2023, we want to be completely transparent with our policies regarding refunds, deferrals, and cancellations. If you are interested in signing up for this race please read this section carefully prior to registering. All interested participants will be shown these policies during the registration process and must agree to adhere to them in order to be admitted to the event.


Race registration fees (and the processing charge from RunSignup) are not refundable. These funds are used to pay for race premiums, permits, supplies, staffing, and other costs incurred before, during, and after the event is held. To be consistent and fair to everyone we cannot make exceptions to this policy.


We offer the option for registrants to defer their entry to the following year's event based on Charm City Run's General Deferral fee schedule:

  • Until February 26, 2023 (2 weeks prior to race day) - $15.00
  • February 27, 2023 - March 11, 2023 (within 2 weeks of race day) - $30.00. 

Registrants may defer their entry by going into their profile on and choosing "Manage Registration" next to the race.


We offer the option for registrants to transfer their entry to another eligible participant up to March 11, 2023 . After this deadline passes we are unable to allow transfers as race materials have been prepped for the event. Again, to be consistent and fair to everyone we cannot make exceptions to this policy. Registrants may transfer their entry to another registrant by going into their profile on and choosing "Manage Registration" next to the race.


2020 showed just how unpredictable our world can be, and the running industry was certainly no exception. We know that it's important to have as much information at your disposal when making a decision whether to sign up for a race or not, and we want you to know exactly what your options will be should the 2023 in-person race not be able to take place as originally planned. Our regular cancellation policy found here covers scenarios that could prompt the cancellation of an event including weather, local emergencies, public health emergencies, etc. If you have any questions about our cancellation policy please email us at PRIOR to registering.


Please note that road closures and parking restrictions will be in effect from as early as 9:00 a.m. EDT on Sunday, March 12, 2023. Between 12:00 noon and 5:00 p.m., people should expect substantial traffic congestion and considerable delays in the downtown area, which will not abate until after the conclusion of the St. Patrick’s Day Parade.

Complete information on the timing of road closures and affected streets can be found under the "Traffic Advisory" section of our race website here.
