Mile High Stair Climb

370 17th St, Denver, CO 80202, USA


Soar to new heights...climb a vertical mile in the mile high city!

Continuing the legacy of the Run the Republic and the Fight for Air Climb, the Mile High Stair Climb is a world-class tower running event benefiting the American Lung Association. The MHSC is brought to you by HAL Sports.

The climb is held at Denver's tallest building, the Republic Plaza, standing at 714 feet tall.  Combine that with being at a Mile High in altitude, and you will be climbing the highest stair climb in the world.

You can choose to conquer 56 flights (1,098 stairs) or take on a true challenge and attend to climb up to eight (8) times for a full vertical mile!

All abilities are welcome (the minimum age to climb is 8), so who is ready to climb a mile at a mile high?
