A MUM-of-three is hoping to break a Guinness World Record when she takes part in the London Marathon next month.

Rebecca César de Sá will attempt to become the fastest female to complete the 26-mile course dressed in film costume. Running as Wonder Woman, Rebecca hopes to break the current world record of three hours, 44 minutes and 18 seconds, something she should be more than capable of, having run four marathons in the last two years, all sub three hours, ten minutes.

The 40-year-old teacher (pictured with the 1st Watson Cub Park, with sons Eduardo and Henry to her left and right respectively) who lives in Burley-in-Wharfedale, said: “I have wanted to attempt a Guinness World Record for some time, inspired by my three boys’ fascination of them.”
