Aust. Long Champs at Hill End, made it half-way to the first control before the R. Knee became too painful for running. Could have returned to the assembly area, but decided to continue walking. During the first long leg started to feel that diarrhoea was coming on (several sandgropers came down with a gastro bug after a pub meal during the week). Managed to finish without an accident, but about half an hour later puked up, and did so again on the way home. Spent most of the evening in bed, and didn't eat anything.
In the circumstances, 30 minutes behind the winner was not too bad, but decided against doing the relays.
Knee problem is possibly due to hamstring and its tightness. Had been experiencing this after the middle distance the previous Saturday, but it seemed to have gone after a couple of days. May have been exacerbated by all the steps on the Grand Canyon walk, and came back with a vengeance today.
