Thanks for the advice guys, it falls into line with what others have said. The run is a bit of fun, but obv theres the serious side as to why im doing it. It'll also be a bit of a life changing experience, personal goals and all that. Determined to actaully run it rather than crawl/walk it! Loosing a few pounds and actaully being fit/healthy is a bonus

Im sure ill be back when im dying
