On October 19th, I am running a marathon that spans the length of London—from Crystal Palace to Alexandra Palace, and back again.

This 26.2-mile double-crossing is a completely unassisted effort. No crowds, no support crew, and no water stations—just one run to try and raise as much money as I can for the Evelina Children's Hospital & Great Ormond Street in London.

Last year, my son received a rare metabolic diagnosis. In that time, not only have we received incredible care from the Evelina this past year, but I've also met some amazing parents on the wards, each going through their own battle. Although we've never been to GOSH I wanted to include them in my charity raising efforts because for me this run is not about raising awareness for my son's specific condition or sharing my story - it's about raising money to help every child, no matter their condition.

If you can support this solo, 26.2-mile run please consider donating what you can. To read more about me and my story visit www.thepallypally.com
