Here's a humdinger of a thought experiment: How fast could people go before the combustion engine and other technologies drastically increased the speed of the human race? And how did they pull it off? Skis? Sled-dogs? Catapults? From ancient horseriders and viking ships to primitive luges and "Russian Mountains", the Outside/In team researches all sorts of old-fashioned methods of locomotion and presents biggest the speed trial of the millennium.

If you've got your own ideas about how humans hit record speeds during ye good olde days before the automobile, send us an email at [email protected] or call us on the Ask Sam hotline: 1-844-GO-OTTER!
