West Auckland mum Sharon Bayford (pictured on left with daughter below) is enjoying a $10,000 windfall thanks to a competitive streak that has seen her drop more than 20kg and four dress sizes.

Sharon (45) went into a national draw with Contours when she, along with hundreds of others nationwide including her daughter, achieved a minimum 5 per cent weight-loss as part of our 6-week Fitness 15 weight loss programme.
