ABOUT THE UNDER ARMOUR B3 DISTANCE SERIES PRESENTED BY KELLY BENEFITS

Welcome to Baltimore's first ever event distance series, sponsored by Under Armour and presented by Kelly Benefits. Join us by sharing in three of Baltimore’s premier events increasing the distance with each event.

We kick things off in March with the fastest and most festive 5K in town: the Under Armour Kelly Benefits St. Patrick's Day Shamrock 5K. Shortly after that we welcome spring and cover a little more ground with the super fun and scenic Under Armour Sole of the City 10K presented by Kelly Benefits. The final leg of the B3 is the Under Armour Charles Street 12 presented by Kelly Benefits, a journey down one of Maryland's most prominent scenic byways.

Race #1 of 2024, the Under Armour Kelly Benefits St. Patrick’s Day Shamrock 5K, has passed. If you would like to upgrade your registration to the B3 Distance Series, please click here.
