There is a lot of information available to help you get the most out of your marathon training. From actual training plans to running forums where you can discuss everything from types of running shoes to what to eat the night before (and of course to share pre-race anxieties).
Undertaking a marathon is a mammoth task; which is why it is good to get first hand accounts, and to share stories that will show you you are not alone. On this page you will find links to some interesting sights packed with information.
More resources and links will be added in time but information overload is a common complaint from first-time marathoners. The above are authoritative and enjoyable and should be enough to go on for now.
