The moment the car hit her, everything changed for Charlotte Roach. Out on a training ride with other Olympic hopefuls, elite athletes all of them, Charlotte was just 21 years old, with the dream of making the GB triathlon team. Now, as she lay on the tarmac with a broken back, waiting for the air ambulance, she was drifting in and out of consciousness, fighting for her life. Nearly two years later, Charlotte sat on her bike in China, waiting for the sun to rise. Ahead of her was a journey that would span 10,000 kilometers.
