About the Under Armour B3 Distance Series presented by KELLY

Welcome to Baltimore's first ever event distance series, sponsored by Under Armour and presented by KELLY. 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 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. The final leg of the B3 is the Under Armour Charles Street 12 presented by KELLY, a journey down one of Maryland's most prominent scenic byways. For 2019 we've added a 2-person relay to the Under Armour Charles Street 12 presented by KELLY and 2-Person Relay presented by HEX, so grab a friend for this monumental race!
