From Hamish:
Day 3 Long Course of 6.5km with a 260m climb at Pwll Du near Blaenavon. This was the hardest day in my opinion as I ran hard in the second day and was tired. The map scale was 1:10, 000. The terrain was high, open land with both large and detailed contour features and rocky outcrops from historic mining activity and large areas of marsh. This did not help as it was the long course. It was a real learning experience for my navigation as I had a few long legs with not much other than contours to navigate off. I made a few mistakes and lost a bit of confidence as well as concentration on some of the longer legs. Next time I think I will try to stay more focussed.
