Sam Smith, of Bramley Drive, in Offord DArcy, was one of 100 mums selected because of their inspirational stories, who took part in the event at Belvior Castle in Grantham, on May 18. The 5k challenge was on a Toughmudder obstacle course including King of the Swingers, Mud Mile, Sewer Rat and Arctic Enema 2.0, which involves plunging into a container full of water and ice. Celebrity mums, including Julia Bradbury, Sinitta and Good Morning Britain presenters also took part. I was on Ben Shephards team along with 14 other amazing mums, each having their own inspirational stories. I was chosen because of Zachery, dealing with his daily struggles and fund-raising for him and raising awareness for cerebral palsy, said Sam. Sam and husband Liam are aiming to raise £50,000 for an operation which could allow their son Zachery, aged 5, to walk independently. The couple have also organised a charity dinner and auction to raise money for the surgical procedure called Selective Dorsal Rhizotomy (SDR), which is not funded on the NHS. The event is on October 14 at St Neots Football Club.
