I did that for my partners 60th - not the Paris Half but the Guy Fawkes '10' in North Yorkshire. They gave her the number 60 so everyone knew who she was and cheered her all the way. There were balloons and a welcoming party for her at the Finish and she was presented with a bottle of bubbly at the prize giving. She hasn't forgotten that one!Why not buy her an entry for her birthday?!
