Last October, my grandma Margaret Parkinson died, a few days after her 92nd birthday. I loved her very much.

She was a wonderful grandma, and a very active woman for most of her life. She loved going for long walks, particularly with her friends and family, and particularly in her native Yorkshire.

For the last few years of her life, though, she suffered from trigeminal neuralgia - a chronic illness that affects nerves in the face, causing sharp, debilitating pain. 

The Trigeminal Neuralgia Association is a charity dedicated to supporting those with trigeminal neuralgia, raising awareness of the condition, and working towards solutions to it.

On May 28th, I am going to run the Edinburgh Marathon in memory of my grandma and to raise money for the Trigeminal Neuralgia Association.

This will be my first - and probably last! - marathon, and I'd be very grateful for any donations you can make to this worthwhile cause.

Thanks!

Fergus
