Thanks Grandel, im waiting on the hospital to contact me at the mo to go for some tests.
Right down to business....got in from work and went straight out again for a very clumsy and awkward 5 mile, never really found my groove tonight and got pretty much everything wrong but still came away with 5 miles in 55 minutes....its under my 12ish minute guideline so its all good I guess!
3:30 - persistence is the key, half the battle is in your mind, "if you THINK your done you ARE!" (forget the book this came from right now!
)
Never ever give up, if your finding it really too hard, your doing it wrong! 
Take a step back and really study what you are doing and try and work out how to make it better, you can absolutely do it!
Try and find the possitive in every run even if it was rubbish use it as a study of WHY it was rubbish don't just discard it as a bad run...bad runs don't exist, its all a matter of perception
