How to read the ladder
Floor
Three in four runners with this 5K ran the floor or faster. In March it sets P100, the number every P-Scale training pace comes from.
Target
What the middle runner ran. Use it for goal pace: rolling 200s and the 1000m readiness check before championships.
Stretch
One in four got there. It is real, and it is not the plan. If a runner is ahead of the target by April, it tells you how far ahead is realistic.
Why a race calculator gets this wrong
A race calculator assumes a flat, accurate 5K, converted to a race run at the same fitness. A November cross country 5K is neither. It was run on grass and hills, and May is six months and a winter of training away.
Fed a championship time from a slow course, the standard VDOT math set the spring 1600m goal 23 seconds too slow for the typical boy and 34 seconds too slow for the typical girl. 98% of the runners who made a spring 1600m final beat it. This calculator skips the conversion and reads what runners with the same 5K actually ran.
Where the numbers come from
Public Lancer Timing results for the New Hampshire divisional cross country championships, falls 2014 through 2025, matched to the same runners’ 1600m and 3200m at the spring divisional track championships. 1,608 pairs from 824 runners. That championship course runs slow, so the curve is built on slow-course times. For each 5K the calculator reads a smooth curve through those pairs: floor is the 75th percentile, target the median, stretch the 25th.
The course setting comes from 2,670 pairs of races: a runner at the divisional championship, then the same runner at the state Meet of Champions a week later on a fast course. Both are championship races. On the fast course they ran about 2.5% faster for boys and 3.5% for girls, roughly 25 and 45 seconds. Fast adds that back before reading the curve. Average adds half. Slow adds nothing.

Common questions
Which 5K should I enter?
A championship race from this fall: conference, sectional or state. The ladder was built from championship races on both ends, November and May. A season best comes from your fastest course on your best day, and it will make every goal too fast.
How do I pick Fast, Average or Slow?
Judge the race, not just the course. A flat course in mud and wind can run Slow. Ask how the front of the field ran that day compared with other years on the same course. A hilly championship course in a normal year is Slow. A flat, firm course on a cool, dry day is Fast. Most courses on most days are Average.
Why are the girls’ ranges wider?
Girls spread wider in the data. Around the typical 1600m, 59% of boys landed within 10 seconds of the target. Only 41% of girls did. That is not a reason to give girls lower goals. It is a reason to give them a range and adjust it early in the spring, when real track times arrive.
Does grade matter?
Younger runners beat the race calculator by more, because they have more growing ahead of them. Freshman boys beat it by a median 49 seconds in the 3200m; seniors by 32. The ladder includes every grade, so a freshman is more likely than a senior to finish on the fast side of the range.
Should my runner train at the target this winter?
No. The ladder says where an athlete could be in May. It does not say how to train in December. Winter is for volume, strength and patience, set by how much the athlete ran in cross country. The ladder comes back in March, when the floor sets P100.
Why does it stop for slower runners?
The data only sees runners who made a spring divisional final. Past about 20:00 for boys and 23:30 for girls on a slow course, and a little sooner on faster ones, fewer than one in twenty boys and about one in ten girls did, so the numbers would describe almost nobody. Below about a third, the calculator flags the ranges as optimistic. For a slower runner, run a 1600m time trial in March and set paces from that.
Does it work for middle school runners?
The data does not say. Every runner in it was racing a high school championship. Treat any middle school number from it as a guess.
The bridge from November to March. Twenty weeks written out day by day, two paths depending on whether your program races indoors, four levels set by cross country peak week.
The spring that follows: the 800m, 1600m and 3200m plans, twelve weeks each, four levels, every rep with each athlete’s split beside it.

Ladder: quantile regression of log spring time on log championship 5K, fit for each sex and event on slow-course times of 15:00 to 19:00 for boys and 17:00 to 22:30 for girls, and read from 14:00 to 20:00 for boys and 16:30 to 23:30 for girls. Below the fastest runners in the data, the target curve continues and the floor-to-stretch spread is held fixed. Course setting: slow-course equivalent = entered 5K × 1.025 (boys) or 1.035 (girls) for Fast, half that for Average. Race calculator: Daniels and Gilbert VDOT equations with the 5K treated as flat.
