Can you run a half-marathon in 1:50:47? A marathon in 2:54:49? Ed Whitlock did both. The half-marathon time was a world record for a male runner aged 85 to 89, breaking the prior record by more than 9 minutes. He ran the marathon when he was 73 and still runs them; he did 3:15:54 when he was only 80.
He seems like a straightforward guy, although he carries only 112 pounds on a 5-foot-7 body. He doesn’t pay strict attention to diet and takes no supplements. He runs with no music, no gadgets, and almost always by himself.
