Beryl Burton: quite possibly the most successful woman youve never heard of.When actress Maxine Peake was given cyclist Beryl Burtons autobiography as a gift she questioned why no one had ever written a play about Britains unsung sporting legend, and so she wrote it herself. The result is an inspirational tour de force fuelled by rhubarb, northern charm and fierce determination.As a child doctors told Beryl that she could never take part in strenuous activities due to a heart condition. When she met future husband Charlie, and he introduced her to the local cycling club, her life changed forever.Proving that she could do anything she put her mind to, Beryl went on to become the greatest woman on two wheels, dominating the sport in the 50s, 60s and 70s: five times world-pursuit champion, thirteen times national champion, twice road-racing world champion, twelve times national champion, British record holder, world record holder, MBE, OBE.Sometimes its the stories that are true that are the most unbelievable.
