I took part in a big cycling event over the weekend (although I should probably confess the lure of the train station just half a mile away was too strong and I wimped out of the second day) and, as I was away from home, my diet consisted of carbs, carbs and more carbs in the form of pizza, pasta and flapjacks. I have absolutely no problem with any of these essential food items but after three days of it, man, was I craving some good old fruit and veg.
