Who’ll come out on top? That’s what Girls vs Boys, our brand new running event, will decide in a fun 'battle of the sexes' challenge. Here’s how it works: get together with a member of the opposite sex – whether it’s your husband, wife, girlfriend, boyfriend, mum, dad, brother, sister, colleague, running buddy or friend – and challenge each other to a 5k race. There can only be one winner! And, while you’re racing each other, you’ll also be helping to raise vital funds for breast cancer research. Participants will receive a Girls vs Boys T-shirt, running number, timing chip, finishers medal, goody bag and £5 Sweatshop voucher.
