glad it's not just me. half way up the 4th hard hill on evening club run (had been out in the morning too) It was like looking through a kaliedescope. Was definately running on empty.
As soon as I started cooling down it was back to normal, and the first thing I reached for in the fridge was a jar of jam with a big spoon, somethign I never do, so body was tellign me to get some sugar in.
Count me in for the full 26, for the price and on your recomendation it'll do for my second. Went up to fort William last year for my first, a marathon is fully recommend, but closer to home and twenty quid is too good to miss.
