How it works

Register for The May 50K today!

Leave your limits behind by walking or running 50 kilometres in May whilst fundraising for life-changing research into multiple sclerosis.
Wherever you live, whatever your fitness level, you can decide when and where you will complete your 50 kilometres.
Every step you take, every kilometre you clock, takes us closer to finding a cure for MS.
You can do it by yourself, or as part of a virtual team with friends, family or work colleagues.
Together we will change the future of MS and leave MS where it belongs, behind us.

How it works


Sign up and set your distance goals.

Share & ask your friends to support you

Tell everyone that you’re leaving your limits behind and get their support for MS research.

Ready, set…go!

Track your kilometres and challenge yourself through May.

The UK MS Society and the MS International Federation 

The UK MS Society is teaming up with the MS International Federation so the money you raise will be shared to fund local and international projects. In the UK 70% of the money you raise will go to UK MS Society projects and 30% will help to fund life-changing research and access to treatment projects around the world.
