Join The Great British Step-Off & raise funds for a cause that matters


Ever wondered what it feels like to climb 20 of the UK’s most iconic mountains? Now you can – without leaving your local park, pavement, or treadmill!
The Great British Step-Off is a free, fun, and flexible virtual challenge where you’ll walk the equivalent of 20 mountains in 30 days – that’s roughly 11,000 steps per day.
Here’s how it works:
✅ Walk anywhere – your street, local park, or even your treadmill.
✅ Track your steps – with Strava, Garmin, Fitbit, or any app.
✅ Split the mountains – one mountain can be completed over several days.
✅ Raise vital funds – choose Immunodeficiency UK as your charity when you sign up and help us support people living with primary and secondary immunodeficiencies.
✅ Celebrate your success – earn a finisher’s certificate when you complete the challenge!
Every step you take helps fund better support, awareness, and brighter futures for those with immunodeficiency.
