Bristol

Gok is in Bristol, where he meets three mental health workers whose careers caring for others has left them little time to care for themselves. As avid cyclers, Becky (32), Tors (33) and Sarah (37) have ditched fashion in favour of bike helmets and high-visibility jackets. It's Gok's job to prize these bikers out of their tomboy threads and turn them into glamorous girls about town. And Brix Smith-Start heads to the world's oldest jewellery house, Garrard in Bond Street, in search of a diamond cuff worth £85,000.
