I spoke to the Practice Manager, rabbited on enthusiastically about C25K and gave her the posters. She did seem genuinely interested and is going to talk to the team about them. I had thought she would have made a decision there and then but they obviously have a system and I didn't want to sound too pushy.
I did think that after my effusive gesticulating and the speed of my speech ( I talk more quickly and more "Irish" when I'm excited) she might have asked me to see a doctor but no.
I will check and make sure they put the posters up. If not, rest assured I'll be on the case!
