Seattle CF StairClimb
About this race
The 37th 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 1,500 stairs, and the half route is up-and-down 750 stairs. Climbers will self-identify if they will sprint, jog or walk 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 at The Hall on Occidental to celebrate.
