We should never give up         

Derek Anthony Redmond (born 4 September 1965) is a retired British sprinter. During his career, he held the British record for the 400 metres sprint, and won gold medals in the 4x400 metres relay at the World Championships and European Championships.
At the 1992 Olympic Games in Barcelona, Redmond tore his hamstring in the 400 metres semi-final but continued the race limping and, with assistance from his father, managed to complete a full lap of the track as the crowd gave him a standing ovation. Although Redmond was disqualified and listed as "Did Not Finish" due to the outside assistance finishing the race, the incident has become a well-remembered moment in Olympic history, having been the subject of one of the International Olympic Committee's "Celebrate Humanity" videos and been used in advertisements by Visa as an illustration of the Olympic spirit and featured in Nike's "Courage" commercials in 2008. 
A man from the bleachers somehow pushed past the security and onto the track. With a few waves of his hand to the security he quickly reached Redmond. No one knew who this other man was at the time except for Derek Redmond.  He burst into tears as the other man puts his arm around him to help support him.  It was Derek’s father, Jim Redmond.
Together they headed for the finish line. With assistance from his father, Redmond  managed to complete a full lap of the track as the crowd gave him a  standing ovation. Completing the race was voted one of the most inspirational   moments in Olympic Games history. 
A true inspiration, Redmond continued to make the most of his life. After being told by a surgeon that he would never run again or represent his country in sport, he decided to prove his doctor wrong.  As a result of this, he began to turn his attention, with the encouragement of his father, to other sports that he enjoyed.
 Redmond formerly served as Director of Development for sprints and hurdles for UK Athletics. He also has played basketball for England and played Rugby 7s. He even went on to play professional basketball for the Birmingham Bullets. Derek’s story is truly inspiring. To top it all off, he now works as a motivational speaker sharing his remarkable story with audiences up and down the country.A true inspiration, Redmond continued to make the most of his life.
