Zach Bitter recently set the new
100-mile (161km) running World Record in 11 hours and 19 minutes.
He averaged 6:48 min / mile = 4:13 min / km and beat the previous
world record by 9 minutes! That's about four sub 3 hour marathons
in a row!! He then continued running another 4.88 miles to run the
12 hours World...
