In 1896 the winning time for a marathon was 2 hours 59 minutes; in 2012, the winning time for master athletes running the same distance was 3 hours 10 minutes for those in the 60 to 69 age group. By analogy, one would expect the record winning time for a half-marathon in 1900 to be roughly the same as the winning time for the fastest 60-year-old today.
