Trail running is not about taking it easy. It’s about getting out of your comfort zone. It’s character building.
Racing in bad weather is not nearly as bad as it sounds (see above point).
My unconventional training is effective. I don’t need to spend hours and hours running each week.
Training on similar terrain would have helped immensely (although where to find mud during a drought, I don’t know. Then suddenly La Niña popped up, turning the course to mud).
I need to carry less food – my pack is heavy enough as it is.
It is possible to run for a long time on fats and little carbs. Perhaps even preferable.
