He hasn’t won any marathons, he would however be the world age group record holder because nobody of that age has ever completed one.

> Singh carried two more documents. One listed him as the first-place finisher at 200 meters (50.26 seconds) for sprinters 100 and over at the 2014 Malaysian Masters Athletics Championships.
> A school transfer certificate had been found. Based on the certificate, he said, Dharam Pal Singh was “78 or so.” And he was not illiterate. The age was corrected on Singh’s election card, but he continued to use an old card “to hide his age,” the civil servant said.
Edit: Oh man, this is a fascinating Wikipedia edit history: https://en.wikipedia.org/w/index.php?diff=785789045&oldid=78...
The information above was originally included in the "Controversy section", sourced from the NYT. On June 15 2017, an editor rephrased the Wikipedia section containing the above information, and reversed the order of the two sentences. However, when they did so, they moved the citation from the _end_ of the two sentences to the _middle_ of the two sentences. Later, on August 9 2017, a different editor removed the second sentence as unsupported (because it was no longer followed by a blue [number]). Thus was the information that some documentation supported an age of "78 or so" lost from Wikipedia.
