The Turner Syndrome Support Society is a charity that is very close to my heart. I hadn't heard of Turner Syndrome before our daughter's diagnosis and since then I've seen first-hand the amazing work this charity does for people up and down the country.

Turner Syndrome is a rare, female only condition, impacting just 1 in 2,500. It is a random event that leads to the partial or complete absence of an X chromosome that has medical implications that can vary in severity and require ongoing management.

Over the last year and a half it has been a great privilege to meet people with Turner Syndrome and to see first-hand the amazing work the charity does to support those living with the condition and their families.

Together with Luke Mason, a great friend from the Army, I will be running The Wall ultra marathon on 15 June 24, a distance of 70 miles (113km), to raise awareness and much needed funds for this remarkable charity that has supported my family and others so well.

I am extremely grateful for any donations...they will be going to a fantastic cause.

Thank you very much.
