Former tennis professional Sue Barker has encouraged people to join the Great Eastern Run to raise money for degenerative muscular diseases.
The player-turned-presenter is president of the Muscular Dystrophy Campaign and says that she has learnt how devastating muscle wasting conditions can be.
"The Great Eastern Run is a superb event that not only gives you the chance to have fun and get fit, but it also enables you to use your muscles for people with less muscle power," she said.
"With every mile you run and every pound you raise you will be directly helping individuals in the fight against muscle disease."
During her tennis career, Sue Barker MBE was the women's champion at the French Open tournament and reached a singles ranking of number three in the world. She is now a chief sports presenter for the BBC.
The run itself will be held on October 15th 2006 and there is a launch event in Peterborough on July 9th, which will help people prepare for the race.
