    Join Charm City Run and ON for our second annual Parking Garage Relay behind Charm City Run's Flagship Store in Timonium.

    Packet pickup will begin at 5:30 PM, and the event will begin at 6:30 PM.

    Teams of 4 will compete as a relay in bracket-style heats, with each winner advancing to the next round until the final matchup determines the champion. Each person will sprint from the top of the garage to the bottom and back until all 4 members have completed the circuit. The route is short, so runners don't need to worry about covering serious mileage, but get ready to outkick the competition!

    This event is untimed, but the winners get some serious prizes!

    Registration is $10 a person - all proceeds go directly to Baltimore Hunger Project.
