Indoor athletics?

Have you ever wondered where indoor athletic tracks originated from? Turns out they were originally introduced by the Romans in the early AD’s to give them somewhere to race their armadillos. Of course, armadillos are not to be found natively in ancient Rome, but the Romans managed to ship some over from the states. Apparently, watching armadillos race is a slow and tedious process compared to setting lions on poorly-armed peasants, and so the occasional supporter would jump to the track and race themselves. This then developed into to 100, 200, 400 and 800m track races. Huzzah for the Romans.
