thE 2025 ALTRA Charles Street 12 & 2-person relay presented by KELLY benefits!


2-PERSON RELAY OPTION

Not up for the full 12? Grab a friend and tackle the race as a team!  The 2-Person Relay follows the same course as the full Charles Street 12 Miler. Leg distances are as follows:

Leg One - The Shops at Kenilworth to Cathedral of Mary Our Queen (4.8 miles)
Leg Two - Cathedral of Mary Our Queen to downtown Baltimore City (7.2 miles)

Bus transportation is available from downtown Baltimore City (race finish line) to The Shops at Kenilworth (Leg One start), and from Cathedral of Mary Our Queen (Leg One Finish) to downtown Baltimore City for Leg One. Transportation is also provided from downtown Baltimore City (race finish line) to Cathedral of Mary Our Queen (Leg Two Start) for Leg Two. There is no transportation provided from downtown Baltimore City to The Shops at Kenilworth after the race.

Each relay participant receives the same race premium and finisher medal. Awards will be given to the top 3 overall relay teams. Relay teams are subject to the same 3-hour course cutoff as the individual runners.

BEER BRACELET

Each registrant in the in-person 12 Miler and 2-Person Relay who is 21+ receives one complimentary beer at the post-race party. We also offer a beer bracelet as an add-on during registration which entitles the wearer to “unlimited” alcoholic drinks at the post-race party. The bracelet costs $28.50. Bracelets are non-transferable, and Charm City Run reserves the right to deny service to anyone who appears intoxicated or cannot produce photo ID when requested.
