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 bottomless beverages at the post-race party. The bracelet costs $23.20. 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.

Downgrades & upgrades

If you signed up for the individual 12-mile race and would like to downgrade to the relay you can make that change through your RunSignup account. Log on, click “Manage Registration” next to the race, click “Transfer Event,” and select the relay. Please note: you will not receive a credit or refund for any difference in price paid.

If you would like to switch from the relay to the individual 12-mile race you can follow the same steps above and select 12-Miler. You will be charged any difference in registration fee from when you originally signed up to the current price.
