Cycled 50km from 8am to 1pm yesterday - from warm climate to under the burning sun of 36°C. This trip will mentally and physically acclimatise me to heat for the summer (which can go as high as 45°C). After this trip, I didn't feel much muscle soreness - but there was some soreness in left knee, which was probably due to me using knees as suspension when rough riding small pits.
I wore a white T-shirt to mitigate heat absortion somewhat. My forearms and lower legs were exposed though and I wonder how much vitamin D my body produced yesterday. May be I should do a test someday!
