“On the 12th of June, I had the joy/pain of walking a marathon from Windsor to Teddington with my teaching colleagues & sister. Before I was diagnosed with MCAS in the summer of 2019, running a marathon had been on my bucket list. However, knowing that would never be possible, due to my condition, as I improved, I so hoped that I would walk one. Mission completed. In addition to raising money for the charity, our school supports one of the Mast Cell Action administrators suggested I use it as an opportunity to support Mast Cell Action. The charity has been my rock since I was diagnosed with MCAS. I am so glad I did. With the right medical support team & friends dreams do come true!” Nancy Vickers.

Scott Fisher - 27 Marathons 

Mast Cell Action Supporter Scott Fisher undertook an incredible feat of running 27 marathons in 27 days!  

Scott's Wife, Megan, lives with many debilitating symptoms caused by MCAS and Scott feels passionate about raising funds for Mast Cell Action to help support those living with MCAS. 

The idea. 'Marathons for MAST Cell originally started when I was making up my wife’s medication for the week. As I put 175 tablets into boxes for a week, I thought. This isn’t good enough; someone needs to do something to help people who are going through this. I started researching challenges and the first one I stumbled across was Eddie Izzards 27 marathons for sports relief. “27 marathons; 27 tablets; we might have something here” I thought.'  Read more about Scott’s fundraiser here. 


"It is honestly amazing what Scott is doing (on top of a taxing job both mentally and physically) I'm so proud of him. I could never have hoped for someone so supportive and willing to push themselves to the brink to raise awareness of such a little understood condition! I couldn't thank or love him any more for what he is doing for me, the MCAS Community, and Mast Cell Action". Megan Fisher.
