How it works

Register for The May 50K today!

Leave your limits behind by walking, running or rolling 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 help leave MS where it belongs, behind us.

Plus, anyone who raises funds will receive an exclusive The May 50K technical t-shirt and over £250 a The May 50K medal*.

*See our T&Cs for further details.
