I am half way through my weight loss journey with slimming world and rhey are trying to encourage their members to do more body magic ( exercise) and have their own charity called smiles that they raise money for, cancer research and alzheimers society. I will be swimming 20 miles over 4 weeks which is 1280 lengths. I have so far lost 5stone 7lbs on slimming world in 18months with still a way to go but I getting there slowly. Any little give will help support 2 charity's that are very close to my heart
