Compare the fields, one distance at a time

A runner is defined here by the cutoff you requested: a published pace strictly faster than 15:00 per mile. Adjust the cutoff or year range to explore how the comparison changes.

Dots show median pace; bands cover the middle 50% of qualifying finishes. Further left means faster. Click a year to open its results.

How to interpret the comparison

Why median pace is the main measure

Median pace is the midpoint of the qualifying field: half the recorded paces are faster and half are slower. It describes a typical finish more directly than a winning time. The middle 50% band runs from the 25th to the 75th percentile, using linear interpolation. Mean pace and the shares under 8:00 and 10:00 per mile give additional views of field depth.

What is included

Each published overall 5K or 10K finisher is counted once, provided it has a valid positive finish time, is faster than the selected cutoff, and is not explicitly labeled wheelchair. Unknown or anonymous names are included when they have a valid time. Five explicitly labeled wheelchair results are excluded from the complete dataset. Unlabeled wheelchair participation cannot be identified reliably from these sources.

The 2014 children’s mile, 2020 mileage challenge, 2023 virtual-only result set, and repeated awards/age-group lists are excluded. The 2020 timed 5K table is included as published; its race format is not inferred. The 5K and 10K fields are never pooled.

Timing and comparison limits

Pace is calculated from the recorded time using exactly 1609.344 metres per mile. Chip time is used where available; otherwise the published finish time is used. Earlier reports do not always identify their timing basis. Displayed paces are rounded to the nearest second; pace differences are calculated before rounding. Qualifying counts describe finishers, not verified unique people or gait: a fast walker could meet the cutoff, and a runner taking walk breaks could miss it.

Changes in the entrants, course, conditions, race format or timing system can affect year-to-year results. This is a comparison of recorded fields, not evidence that one course or year was inherently harder. Always look at sample size; the 2020 field is especially small. Published errors are not silently corrected, and there are no missing or non-positive times in the included distance-result dataset.

Audit and sources

All source reports remain in the annual pages and originals folder. The default 15:00/mile summary is available as CSV, and the rules are recorded in the method file. Results were captured November 4, 2026; the analysis was prepared November 5, 2026.
