👟 Step Up for a Cause! Join the MCAS Step Challenge and stride towards a brighter future with each step you take. Whether it's five steps, a thousand steps or ten thousand steps, every stride counts in our mission to raise vital funds for the MCAS community.

Step into action and make a difference for the MCAS Community by setting your own personal challenge. This inclusive event invites everyone to participate at their own pace, ensuring that every step brings us closer to our fundraising goals.

Your steps will help people like Megan, As a child Megan had mild allergies to hay and tomatoes, suffering from anaphylaxis for the first time as a teenager. Now she is wheelchair-bound, has faced death multiple times and is fighting for more awareness of her condition. Her allergic reactions are regular and intense and she has spent years in and out of hospital struggling to find answers.

“Thankfully, the Mast Cell Action website and research papers have been pivotal in stopping the medical gaslighting and forced professionals to listen to us” Scott Fisher, husband of Megan.

We are the only UK charity providing support, information and guidance specifically and exclusively to the MCAS community and health professionals.

Together, we'll walk, jog, or run towards better awareness, research, and support for those affected by Mast Cell Activation Syndrome. Lace-up your shoes, sync your fitness tracker, and let's step forward as one community towards a healthier tomorrow.

Join us for the MCAS Step Challenge and let your steps speak volumes for those who need our support the most. Together, we can make every step count!

If you aren’t able to participate in our MCAS Step Challenge, please share the event with your friends, family and colleagues – and ask them to get moving for MCAS.

Whatever your challenge, we will cheer you on, supporting you from the sidelines!
