I don't know how they run this at alleycats, but in the old days when every bike was a fixed gear (like in the 1880s, I mean), bicycle races and exhibitions would always have a slow race, mostly for comic effect, in which riders vied to finish a course last without falling over. Of course, they were riding high-wheelers, so putting a foot down wasn't even an option - you really toppled in a big way and there was real injury potential. This was also an era in which people liked to bet on how many rats a dog could kill in a certain period of time.
