Born on a farm in the Brecon Beacons, Delyth Prothero grew up passionate about athletics. After a serious injury ended her competing career as a discus thrower, Delyth turned her attention to coaching. By the 1990s, as Wales team manager, she was responsible for some of the biggest names in British athletics, including Colin Jackson, Iwan Thomas, Jamie Baulch and Matt Elias.This programme celebrates Delyth's understated success with warmth and humour, as some of the superstars of Welsh athletics come together to pay tribute to the woman they all called Mam. It takes a look at the role she played in their lives both on and off track, as the athletes tell previously unheard anecdotes describing the highs and the lows of winning medals.Culminating with a reunion of the 2002 Manchester Commonwealth Games 4x400m relay team, the programme discusses the most controversial race in Welsh athletics history. Modern day computer technology is used to try and finally settle who should have won gold that day: England or Wales?
