Notes
Burnt by sun badly, even through the cap (or the cap overheated the brain, but saved me from burnt skin, so there was no solution, except training on hot days). The weather did change within 2 days, so there was not much chance to get used to it.
Anyway, I felt still very weak, no endurance at this moment, muscles+gait reasonable for non-running months before, but endurance is completely gone.
