In 1984, the women's marathon was held in the Olympic Games for the first time. But to the horror of the crowd in Los Angeles, one of the runners, Gabriela Andersen-Scheiss of Switzerland, entered the stadium in a state of virtual collapse from heat exhaustion and took minutes to stumble round her final lap of the track. Andersen-Scheiss tells Ashley Byrne about her ordeal. The programme is a Made-In-Manchester Production.
