Concrete Climb Half Marathon, 10K & 5K

Columbia, MD

This one-of-a-kind event transforms a 9-level parking garage into a run course where runners will tackle a Half Marathon, 10K, or 5K by looping up and down the ramps. Staged at the top of the garage, runners will climb level after level, and fly through fast descents. It’s gritty, fun, unconventional, and built for athletes looking to break away from the typical road race. Whether you’re chasing a PR, conquering the climb, or just looking for an unforgettable experience, this event delivers a bold twist on racing that’s equal parts challenge, excitement, and pure fun.
