He continued: "Received so much stick n lots believed I wouldnt do it but proved those Haters/Doubters wrong! Hope Granddad Seamus is proud! #CancerResearch."
The Essex celebrity, who has raised a total of £3,313 for Cancer Research UK, added: "As @justinbieber says #NeverSayNever #VirginLondonMarathon2012 #CancerResearch @carakilbey @BilliMucklow NEVER FORGET! Lifetime Achievement!x"
