Personal Trainer

Not sure if I mentioned it or not but I convinced a couple friends to do a 1/2 marathon with me in October. I have bee wanting to do a half marathon for some time and so I mentioned it & they all agreed to join me. I have been wanting to do it for some time & decided this would be the year. I have 7 months to train for it and I will need every last day. Tonight one of my friends & I have a meeting with a personal trainer at the gym to see about hiring him to train us. I am a bit nervous to see what he will have planned for us.
