The ultimate obstacle course challenge now has 12+ obstacles over a 5 Kilometre run.
With no competition and no timing, it’s just you, your teammates and muddy strangers working together to conquer the course and earn the world-famous orange headband.
We are the National Axial Spondyloarthritis Society (NASS) and we seek to transform the diagnosis and care of people living with axial SpA. It’s an invisible and misdiagnosed condition. Often leaving people feeling powerless, in increasing pain and extreme exhaustion.
