We were at the Paralympics on Super Saturday, enjoying an amazing spectacle of Olympic feats - just breathtaking - when the mens 1500m race started.
They all lined up and set off smartly except for one little guy at the back, who really seemed to be struggling, with what looked like a painful foot. The main bunch of runners lapped him not once but twice and still he struggled on. We all thought he would give up, but no - when all the others had finished and returned to the dressing room, he doggedly carried on.
80,000 people watched as he went round, slowly, all on his own. We all stood and cheered as he went past and when he crossed the line the applause was earshattering. But he just walked off. I don't think he even realised that we were clapping for him.
Houssein Omar Hassan I feel should have been awarded a gold for sheer determination not to let his country down or himself be beaten - all on his own, with the whole world watching. He was incredible. A true Olympian!
