Don't feel like that. I still ask lots of questions and you can bet that others will be wondering the same things. Even though you're not doing your marathon till the Autumn I'd advise you pop into the marathon page and join in one of the threads. There are going to be 10-12 new ones starting in the next couple of weeks (asics and forum 6) covering every time from 3 - 6 hours. Perfect time to join in.
