The May 50K is a community fitness and fundraising challenge for MS International Federation and partnering charities, including: MS Ireland, the MS Society UK, Stichting MS Research and Deutsche Multiple Sklerose Gesellschaft Bundesverband. We're challenging people to walk, run or roll 50 kilometres throughout the month of May to raise funds towards life-changing research into MS, as well as an international initiative to improve access to vital treatments for everyone affected by the disease - no matter where they live.

Everyone who receives a donation to their page will get a The May 50K t-shirt. And everyone who receives over €250 in donations will receive a The May 50K medal. See terms and conditions for more information.

It’s completely free to register and participate in The May 50K. You can sign up here and leave your limits behind this May!

The May 50K is an online fitness challenge which runs for one month from 1^st May 2026 to 31^st May 2026. You decide where and when to complete your challenge.

Wherever you live, whatever your fitness level, you can decide when and where to complete The May 50K. Really don’t like to run or walk? You can complete the challenge in a way that works best for you. If you are a wheelchair user, you can adjust the kilometres in a way that will be challenging for you. Setting a challenging personal goal will make it more likely others will sponsor you.

Absolutely! It’s up to you to decide where or how to complete The May 50K.

MS Ireland is teaming up with the MS International Federation so the money you raise will be shared to fund local and international projects. In Ireland 70% of the money you raise will go to MS Ireland projects and 30% will help MSIF rally the global community to prevent, treat and stop MS, improve access to treatment and support projects around the world.
