Seattle CF StairClimb
SODO, United States • 17 Sep 2025
Event overview
The 37th Annual Seattle CF StairClimb is a fundraising stair-climb at T-Mobile Park in Seattle to benefit the Cystic Fibrosis Foundation. Participants climb in the stadium 300-level section on set routes that involve repeated ascents and descents of stadium stairs. Climbers self-identify as sprinting, jogging, or walking and are sent out in waves with faster climbers first. The event offers an organized gathering at the end of the climb at The Hall on Occidental.
