Unfortunately, my throat is getting worse, so this story is going to be a bit incoherent.
We left off at how the start happens. I was in the second-to-last corridor - there were no corridors behind me and people were just crowding in randomly because their numbers were over 5000. In front of me in the corridor were the Laima folks, and many of them were squeezing into the wrong corridor, making the excuse that they wanted to be together. Very touching, but they were getting in everyone else's way, since the corridor fits a calculated number of participants, and the rest have to step on each other's toes, or worse, scratch each other's bikes. The organizer girl looking after our corridor couldn't stop the outrage, even though she warned the Laima people about possible disqualification.
Some dude hauled a kid in a stroller the whole distance, and I only managed to pass him halfway through.
