I have run 5 marathons with times from 3:42 to 4:08. I am not fast but I really don't train to be fast so it's my own fault. However, I agree with Sue as I do feel a bit like an elitist sometimes and being the only marathoner in my group of friends I get treated with a sense of awe sometimes. If you ask me I would say you have to have a bit of that in you in order to make it though the mental side of the run.
Hopefully, I can break my PR in Rhode Island on Saturday. It's not really my goal but I am in much better shape than I have been for my other 5 runs so I think it will just happen. If the weather is good and I feel good I think I can do it.
