Derek Redmond tore his hamstring in the 400 metres semi-final at the 1992 Olympic Games in Barcelona. He fought through the pain and, with assistance from his father, managed to complete a full lap of the track as the crowd gave him a standing ovation.
This is what he thought as he was crouching, injured in the middle of the track:
'Everything I had worked for was finished. I hated everybody. I hated the world. I hated hamstrings. I hated it all. I felt so bitter that I was injured again. I told myself I had to finish. I kept hopping round. Then, with 100 metres to go, I felt a hand on my shoulder. It was my old man.'
The track playing in this clip is 'Fix you' by Cold Play.
