I was in an event on the weekend covering 100km. As a team of four we each carried appx 5kg.
We bettered our time, as we have done four times before.
I showed no obvious signs of a cold beforehand but immediately after it's all on. Chest, voice, throat.
This time I was the weakest of the four, only noticeable on the uphill. All the time struggling at half their pace.
It was pretty much the opposite on previous occasions.
I ate very little enroute but plenty beforehand. Everything I recall trying on the walk tasted shocking. I had to spit it out.
Sandwiches, even banana to some degree. Chewing gum was bad.
My question to others is 'have you ever experienced the food tasting bad as a result of fatigue?
It may well have been the cold developing in me.
