Your daughter has the right attitude WW. Good luck with your first 10K, which one are you doing?
About the 'other mums' bit, I know for a fact at least 2 of them do go running, I think it was being seen all sweaty and dishevelled by her friends that so bothered my daughter. Anyway, now she's 13 my presence on this earth is increasingly a source of total embarrassment were it not for providing her with food and shelter for a few more years!
