I'm running the Edinburgh Marathon dressed as a Globe for Worldwide Cancer Research.

This is for Gran Mechie, Christine Brown, Gran Moss and Grandpa Moss. I'll be running with a tear in my eye, but love in my heart. With the memory of these incredible, brave and inspiring people every step of the way.

Gran Moss survived her cancer diagnosis. We lost Grandpa and Christine to Pancreatic cancer, and Gran Mechie to bladder cancer. I never knew my Grandpa because his life was cut short by Pancreatic cancer six months after I was born. 1 in 2 of us will be diagnosed with cancer. A pitiful 1% of people survive Pancreatic cancer after five years. In Scotland, sadly 44 people die every day from cancer.

The aim is to set a Guinness World Record for a marathon dressed as an astronomical body (a Globe). I need to run faster than 3:30:36 every step in full full costume. However, the logistics are still to be confirmed. There are very tight rules I need to follow, but I'll be running as a Globe regardless.

I will look daft. It'll be tough. Marathons are not fun, they're too long, painful and energy sapping. But helping our loved ones and those living with cancer is what counts.
