> everyone heralds Jim Hines for breaking 10 seconds in 1968 but not many acknowledge the fact that the Mexico 1968 was the first Olympic Games to use the Tartan track surface

Also, Mexico City's thin air: http://www.chiefscientist.gov.au/2011/05/running-on-thin-air... Bob Beamon set his insane long jump record there as well.

Edit: But looking at the all-time list [1], Jim Hines' run is still pretty impressive, surrounded by times run some ~50 years later.
