[USMA:51471] Walking speed

[Harry Wyeth]

As a general rule, a brisk walk on a flat surface covers 100 m in one 
minute.  That is 1.66 m/sec.  I can do my feeble version of racewalking 
at 8 minutes/km, or a little faster, or 125 m/min or 2.08 m/sec.  
Competitive racewakers go much, much faster, of course.  On a few 
occasions (not recently!) I have passed amateur-class racewalkers in 
marathons who were still maintaining a pace that would bring them in at 
3:45 or so, or 42.2 km in 225 minutes, or 187 m/minute.
