Mimi Anderson started running at the age of 36. She wanted more shapely legs and so hit the gym. Mimi had a history of eating disorders, but her newfound love of running forced a change in her relationship with food and her body image. She went on to become a record-breaking endurance athlete completing feats such as the Marathon des Sables and becoming the fastest woman to run the length of Great Britain. The training and competitions did lead to those thinner legs. But when she got them, she realised she didn't want or need them anymore. Her latest book is called Limitless.
