Welcome to Baltimore's first ever event distance challenge, sponsored by Under Armour. Join us by sharing in three of Baltimore’s premier events increasing the distance with each event. The Under Armour KELLY St. Patrick's Day Shamrock 5K, the Under Armour Sole of the City 10K presented by KELLY, and the Under Armour Charles Street 12 presented by KELLY will make up the series. Why not set yourself or a loved one up in 2017 to go the distance and participate in all three of these exceptionally fun running events?
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.
