Pace over time: 99 races and 18 splits from 2008 to 2026, ranging from 1.12 to 10.92 kilometres per hour, where higher is faster. A second, age-graded series is drawn above it; the gap between the two is the age credit.

5 results are not on this chart. They are counted in every statistic above and listed in full below — backyard ultras carry a lap count instead of a pace, which is the number that means something in that format.
