Hi, my name is Callum. I'm 17 years old and currently in my first year of A-level courses at Furze Platt Senior School taking English Lang/Lit, History, Maths and Physical Education. I'm going to be taking part in the RBC Race for the Kids 2014 to raise money for Great Ormond Street Hospital Charity.

I have been a patient with GOSH for 16 years now after being diagnosed with a 'Tracheoesophageal Fistula' at birth, and having had 12 operations in my life time, 8 of which were performed when I was 3 or less years old... So I feel I owe a lot to the hospital for being able to help me to be where I am today, so this is my way of giving back all they hospital deserves. As the advert says, 'There's always a place in your heart for Great Ormond Street Hospital' and in my case there is and always will be.

The target is to reach £1000 which would be incredible for me to achieve for the charity, and anything over this target would be amazing! So if you can please sponsor me and play a part in changing the lives of children who deserve the best treatment at the best children's hospital!

Thank you!
