Pretty poor show from myself. Navigation easy, although the map a bit odd. Had 2.5m contours but not enough contour detail to justify it and also to mask the most intricate area of contours were rides marked every 30m or so, also unnecessary.
Anyway, was running ok but knew before I started I really should have taken some energy with me, especially due to the heat. So about 2-3k from the end I completely faded, barely getting myself to run and taking long breaks at the controls. I can pinpoint exactly when I started realizing I was heading this way but that's not really relivant as it needs to be caught much earlier. Not that I had anything I could do about it.
Think up to about 15 mins due to energy loss.
