Aren't there some trackways of humans running in Australia, that supposedly show ancient shoeless aboriginees, on uneven ground, could almost match the speed of Usain Bolt running in the Olympics?

This is a press article you may be thinking of:

Many prehistoric Australian aboriginals could have outrun world 100 and 200 meters record holder Usain Bolt in modern conditions.

These and other eye-catching claims are detailed in a book by Australian anthropologist Peter McAllister entitled "Manthropology" and provocatively sub-titled "The Science of the Inadequate Modern Male."

His conclusions about the speed of Australian aboriginals 20,000 years ago are based on a set of footprints, preserved in a fossilized claypan lake bed, of six men chasing prey.

FLEET-FOOTED ABORIGINALS

An analysis of the footsteps of one of the men, dubbed T8, shows he reached speeds of 37 kph on a soft, muddy lake edge. Bolt, by comparison, reached a top speed of 42 kph during his then world 100 meters record of 9.69 seconds at last year's Beijing Olympics.

In an interview in the English university town of Cambridge where he was temporarily resident, McAllister said that, with modern training, spiked shoes and rubberized tracks, aboriginal hunters might have reached speeds of 45 kph.
