add remove

The May 50K is an online fitness challenge which runs for one month from 1st May 2023 to 31st May 2024. You decide where and when to complete your challenge.

What do I have to do?

add remove

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.

What about coronavirus (COVID-19)?

Obviously our first priority is your health. Follow the official advice and don’t put yourself or anyone else at risk. People with MS  may be at an increased risk of complications from a COVID-19 infection, so at this time it is especially important for people with MS and their caregivers to observe recommendations about social distancing.

One of the best things about The May 50K is that you do it on your own, even when you’re in a team. So you can keep your distance and run the distance!

Can I swim or cycle my May 50K?

add remove

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


Where do the funds go that I raise?
