Boring bicycle commute - 20250625 #2

Warning: even I find it to be extremely boring. Don't know what it was yesterday, but I had an extremely hard time just getting home. Even had to make a rest stop. I don't /think/ it was the heat (34°C/93°F when I started, 30°C/86°F at home), as it was even warmer when I cycled to work at around noon. Or it wasn't the heat alone, but combined with the annoying headwinds?
