Built from 24,887 results of 15,030 New Mexico runners in 208 race events from January 1, 2025 through October 17, 2026 (RunSignup 15,104, irunfit.org 9,198, TCR 585). A runner counts as a New Mexico runner when their home state is NM or left blank at a New Mexico race. Virtual, trail, walking, and combined events are left out. Other distances are kept but not ranked.
How the ranking works
This is the method of the high school rankings, run separately for each distance and for women and men. Lists are by 5-year age group. A runner's results within one age group are combined and shown at the greater age; a runner whose age crosses into a new group during the year is ranked separately in each. When the ages on race day cannot belong to one person and the cities differ, each city is taken as a different runner. One race is enough to be ranked.
Speed, 60%. Times on different courses are not comparable, so each race gets a difficulty, worked out together with each runner's ability from every New Mexico finisher's times at that distance. A runner who ran two races ties those races together, so the difficulty covers the course, altitude, and weather. A race that no shared runner ties to the rest is taken as a typical course. A time far off a runner's other races counts for less. The rating is a weighted average of the runner's races, with a race's weight halving every 90 days and the worst race dropped once there are three. A runner with few races gets an allowance that shrinks with more races: how much a runner's times vary from race to race at that distance (about 4% at 5K, about 3% at 10K, about 4% at half marathon, 3% where too few runners repeat a distance), divided by the square root of their races. Rated is that rating, without the allowance, as a time at the distance on a typical course.
Placing, 25%. Each finish scores its overall place in the whole field, times the field's strength: how highly its top 10 New Mexico finishers are rated.
Head-to-head, 15%. The top 100 of each age group by speed and placing are compared in the races they shared. Then a runner moves up past the one just above when they beat that runner in most of their races together and their ratings are within 1%. Vs. top 100 is the runner's record against the others in that group.
Runners are matched across races by name, sex, and age group. One runner listed under two names is joined when the names are a nickname or shortening of each other (Steve and Steven), differ by one letter, or have first and last name swapped, and the two never ran the same race. Two people with the same name can still be joined by mistake.
