About the Project Sebastians Rare Stair 2
The Rare Stair Challenge takes place at Central Park in Santa Clarita and is built around one simple task: climbing flights of stairs. You go at your own pace and turn around when you are done, so the effort is entirely up to you. The connection to rare disease advocacy gives the morning a clear purpose beyond the physical challenge.
