A Global Collaboration

There are over 2.8 million people around the world living with MS and in every country, life is different. At the MS International Federation, it’s our mission to leave MS where it belongs, behind us. 

DMSG (Germany), Stichting MS Research (Netherlands), the UK MS Society, and MS Ireland are world-leading MS organisations and they have all come together with the MS International Federation to bring you The May 50K! Together we have committed to increase funding for vital MS research worldwide,  improve access to effective treatment and support for everyone – no matter where they live . The May 50K is one of the most important ways we can help achieve those goals, so the only thing we leave behind us is our limits.

Without working together the world could miss out on international collaborations that can speed up research and reduce duplication of effort. Be part of a faster, more connected world of research!

Without working together there would be nobody taking the fight for access to affordable treatments to the global level. We are stronger when we all run together!
