Welcome to The May 50k 2025!

There are over 150,000 people in the UK living with multiple sclerosis. It’s our mission to leave MS where it belongs, behind us. The MS Society UK has teamed up with the MS International Federation once again for The May 50K.

Walk, run or roll 50K in May whilst raising money for life-changing MS research and improved access to treatments for all. Wherever you live, whatever your fitness level, you can decide when, where and how you'll complete your 50K.

You can do it by yourself, or as part of a virtual team with friends, family or work colleagues.

Plus, anyone who raises funds will receive an exclusive The May 50K technical t-shirt or MS Society t-shirt. And if you raise over £250 you'll get a The May 50K medal*. (See our T&Cs for further details.)

A UNITED FRONT

The MS Society UK 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 MS Society UK's Stop MS appeal and 30% will go to the MS International Federation to fund life-changing research, improving access to treatment, and support for people living wih MS around the world.

The MS Society is the leading UK charity supporting everyone affected by MS. Our vision is a world free from the effects of MS and our mission is to enable everyone affected by MS to live life to their full potential. We provide a range of front-line services designed to empower and support people affected by MS, to maintain their independence, quality of life, and to reduce social exclusion.
