Just for fun, here's the world record holders for 5K times...
World's Fastest Men's 5K: Ken Bekele of Ethiopia in a time of 12:37.35
World's Fastest Women's 5K: Meseret Defar of Ethiopia in a time of 14:16.63
Insane. Sick. Amazing.
And here's a fun video I found...not sure if Ken or Meseret met a lion that forced them to run that fast but I'm thinking being faster than your friends is also a big advantage at times. :) Happy Friday!
