38th Annual Seattle CF Climb 2026

The 38th Annual Seattle CF StairClimb is a challenging and unique fitness event where participants climb up and down the stairs in the 300-level section of T-Mobile Park in a test of endurance and time. The full route is up-and-down 1,800 stairs, and the half route is up-and-down 900 stairs. Climbers will self-identify their pace and will be sent out in waves with the faster climbers going first.
Whether climbing to test your endurance, to improve your time or to simply cross the finish line, this event is a great way to spend the day with co-workers, friends, or family while helping the Cystic Fibrosis Foundation fund the research and care needed to help advance a cure for this disease. At the end of the climb, participants gather at our official after party to celebrate.
