<P> At the 1991 World Championships Redmond was a member of the British team that shocked the athletics world by beating the much - favoured American team into second place to claim the gold medal in the 4x400 metres relay . Redmond ran the second leg in the final and, together with teammates Roger Black, John Regis and Kriss Akabusi, ran what was then the second - fastest 4x400 metres relay in history . </P> <P> Injuries consistently interrupted Redmond's career . At the 1988 Olympics in Seoul, he pulled out of the opening round of the 400 metres 90 seconds before his heat because of an injury to his Achilles tendon . Before the 1992 Summer Olympics, he had undergone eight operations due to injuries . </P> <P> Redmond was in good form by the time of the Barcelona Olympics . He posted the fastest time of the first round, and went on to win his quarter - final . In the semi-final, Redmond started well, but in the back straight about 250 metres from the finish, his hamstring tore . He hobbled to a halt, and then fell to the ground in pain . Stretcher bearers made their way over to him, but Redmond decided he wanted to finish the race . He began to hobble along the track . He was soon joined on the track by his father, Jim Redmond, who barged past security and on to the track to get to his son . Jim and Derek completed the lap of the track together, with Derek leaning on his father's shoulder for support . As they crossed the finish line, the crowd of 65,000 spectators rose to give Derek a standing ovation . However, as his father had helped him finish, Derek was officially disqualified and Olympic records state that he "Did Not Finish" the race . </P> <P> Redmond's struggle in the 1992 semi-final later became the subject of one of the International Olympic Committee's "Celebrate Humanity" videos, which proclaimed: "Force is measured in kilograms . Speed is measured in seconds . Courage? You can't measure courage". In 2008, Redmond was featured in the "Go World" series of Visa advertisements promoting the Olympic Games . The advertisement highlights his 1992 injury, noting that "he and his father finished dead last, but he and his father finished", narrated by actor Morgan Freeman . </P>
