"Back in 2009 in my late 40’s I'd been suffering headaches for quite some time.  One afternoon as I was leaving work I took a tumble and ended up in hospital. That was the point at which it all changed.  I was diagnosed with a frontal lobe brain tumour, a Meningioma.

The op was a success and, despite also having to get through pneumonia while in hospital, when I was discharged home I was so very lucky as I didn't have any chemo or radio to have to deal with, just a big scar, some hair growing challenges and some headaches until everything mended. 

During my recovery, I took the opportunity to re-evaluate my health going into the future. I decided to join a running club and the rest is history. I've since completed hundreds of races including almost 50 half marathons and 8 full marathons, including London in 2014 and 2015.  

Sadly, after my London marathon in 2015, I suffered a relapse and once again they had to perform an emergency operation to save my life. They performed the op and I woke up with no bone flap as it was too infected to keep it. In the meantime, until they were able to insert a titanium plate I was to wear a helmet to protect my brain.  

I wanted to help promote awareness while wearing the helmet so I took part in a couple of races including the Bath Half Marathon and my marathon comeback last April at London, where I ran in the colours of Brain Tumour Support whilst wearing my helmet. 

My overriding thought is how lucky I have been through the whole process. I feel I've had to endure so little compared to some of the stories I've read."
