I was just feeling really good that day and thought I'd see how far along I'd come," Owens said following his sensational 40-yard-dash, electronically clocked in a record 4.19 seconds at a speed camp in Berkeley, CA, on what is considered a "slow track". Owens, who broke his own record for the track of 4.33 seconds set several months earlier, had recently defeated rookie 49ers wide receiver Michael Jennings, a former Florida State track star, in an impromptu 40-yard-dash in Osaka, Japan. He decided the time was right to see just how fast he had become.
Owens had trained hard all off-season long in both 2001 and 2002, putting primary focus on improving his speed.
"It's not that I wasn't already fast," said Owens, "It's just that I knew I could get much faster if I really concentrated my efforts on improving the performance of my fast-twitch muscle fibers. I'd already come a long way, but I could really feel my body starting to change into one that could do special things from an explosion standpoint, so I decided to see how far I could take it."
The results were breathtaking, as Owens followed up his awk-inspiring display in defeating an elite track athlete by running what is believed to be the fastest legitimate 40-yard-dash time in NFL history.
"To be honest, I thought I could have run a little better," said Owens afterward, "I had run a 4.33 on this track immediately following the 2001 season, and that was against the wind, and Mike (Jennings) had been hand-timed in the 4.19 to 4.21 range before, so I thought I had a chance at getting under 4.1. But I ain't complaining." Since Owens's run in 2002, no athlete has run better than 4.39 on this surface.
