Date of Birth
I reached the summit of Kilimanjaro on the weekend, I want to wholeheartedly thank James Calder & the team for your contribution to my journey, you were the first people I thought of when I got up there.
Following an ankle injury last year, I was left unable to run. James, with the help of his fantastic network of colleagues, has helped me get back to running which has meant that I have won both a 5k and a 10k race this week and I am currently in training for the London Marathon, Three Peaks Yacht Race and Marathon des Sables.
I would like to say a huge thank you for the incredible job you did on my left ankle. One year since my surgery, I completed today's Taunton Marathon in just under 4 hours. I am really grateful for what you did… it has changed my sporting life!
