A Global Collaboration

The UK MS Society, MS Society of Ireland, Stichting MS Research (Netherlands) and Esclerosis Múltiple Argentina are leaders in the MS International Federation. Together we have committed to increase funding for vital MS research worldwide, and improve access to effective treatment 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!

The MS International Federation is the global body for national MS organisations and will be leading the event in the US and Canada, with the endorsement of its members, The National Multiple Sclerosis Society and the MS Society of Canada. If you are in either of those countries and would prefer to participate in one of the many incredible events directly supporting the National Multiple Sclerosis Society click here, and click here for the fabulous events run by the MS Society of Canada.

You can find out how the money is split and what it funds on each countries dedicated sites: Ireland, Netherlands and the UK.
