1 With the possibly exception of Robert Reeder, a semi-professional runner and Carnegie Mellon University graduate, who won the Las Vegas Marathon in 2000 in a outstanding time of 2:17:15. Robert's most recent marathon finish (via http://www.robreeder.com/) was recorded at 3:18:26. Thank you to Jonathan McCune for making me aware of Robert's achievements. I will keep the time 3:18:26 in my mind...
2 And with the further exception of Alan Turing who ran a cross-country race in 1948 in a time of 2:46:03. A time which was just 11 minutes slower than the winner in the 1948 Olympic Games!
