I thought some of you might be interested in seeing a moving image of
the former (as of 29 Sep 2007) world record holder for the 20K
racewalk. The animation can be viewed at

www.philsport.com/narf/c1per.htm

The animated sequence of photographs is of Jefferson Perez
racewalking in a 10K race at Niagara Falls. The animation has been
calibrated to approximate his 10K walking speed of about 6 minutes
per mile.

Perez is from Ecuador, won the 20K gold medal at the Atlanta Olympic
Games in 1996, and recently held the world record for the 20K
racewalk with a time of 1:17:21 (averaging 6:13.4 per mile for the
12.4-mile race). While top racewalkers display a wide variety of
walking styles, Perez has a very smooth style that includes very
little side-to-side hip motion.

I made the animation (with permission) based on photographs taken by
Jeff Salvage and displayed at his Racewalk.com Web site. The
photographs were edited to remove background distractions, reverse
the direction of walking, and insure proper alignment. Jeff's
photographs can be seen at

Hope you enjoy the animation.
