I have bonked several times but always kept going. Legs are dead and I feel really heady but I know that it is just a severe lack of energy and food inside of me. My issue is that I can't sort my food out during a long run even 15 milers and I am unlikely to eat other than a single gel. I just find that food does not sit well inside me stomach so I tend to eat ready break/porridge before hand and pop the occasional gel during the event. During this years fellsman I only ate an 2 apples at dent, bowl of pasta with cheese at stonehouse, a hotdog at cray and a soft cheese sarnie with spaghetti hoops at top mere (?). I would certainly say that this is not enough to fuel a 14 stone body over this distance. My feeding is something that I will continually have to learn about and adapt. Just like I have now learnt that a citrus flavoured drink or coffee within 90 minutes of a hard race will have me up chucking, the last time it happened i was doing 80 driving down the m4 - thankfully my therma cup was empty but it had to be emptied twice out of the window. Personally I am always finding issues good and bad with my feeding during an event, I'm always ready to learn from others experiences and their greater knowledge.
