School boy error

School boy error at the Brecon ultra, didn't eat properly and my body run out of sugar and scary things happen when you get go that point, well you say i didn't eat properly during the race i eat everything i had and nothing different to what i normally carry during race like this, the difference was that i didn't eat properly leading up to the race so i started on half empty, add that to the fact we flew round the first lap (23 miles in 4hrs on that course is quite quick for me) anyway it's another 35 mile training run!, i have some time off leading up and over Christmas so the plan is to do the full distance (48 miles) during that time.
