100m Hurdles progression by age

a girls' 17.00 100m hurdles at 14 projects to 16.39 at 18 on the TrackReels curve derived from USATF age-division records.

Enter your current age and your best fully automatic 100m Hurdles time. The tool holds your relative standing constant and prints the time that level is worth at every age to 30, from a curve TrackReels derives from USATF championship records by age division (ages 14 and up: the youngest division with a published record). The 100m Hurdles is a girls' race at every level this curve covers, so the tool projects it for girls only.

What a 100m hurdles time at 14 projects to

Four starting points carried forward on the same curve. A freshman season is the age most families first ask the question, which is why 14 is the starting column.

Girls

The last column places the age-18 projection against the published college recruiting standards for the 100m Hurdles. See the full ladder for girls.

How the projection works

No governing body publishes youth age factors for jumps, throws or hurdles, so this curve is TrackReels' own, built only from published records. USA Track & Field publishes the championship meet record for every age division of its Junior Olympics, for its U20 championships and for its open championships: one governing body, one athlete pool, every age from 9 to open class. Each division record, as a fraction of the open record, is the factor for the top age of that division; between divisions the factor is a straight line, and from 25 it is held at 1.0, the same open-age plateau the WMA tables use. Your relative standing against that curve is the one number held fixed: the tool asks what time the same standing is worth at each later age, with the implement or hurdle height that age competes with.

In one line: time at age B equals time at age A, times factor(A), divided by factor(B). The records are printed below, so every factor can be checked by hand.

Equipment changes on this curve (girls: 30 in in the 13-14 division to 33 in in the 15-16 division). A projection across one of those steps is the same relative standing with the heavier implement or the higher hurdle, which is why a throw can project to a shorter distance a year or two later: that is what happens to a real athlete at the change, and the curve does not hide it.

What it cannot know

It knows nothing about you. A growth spurt, a new coach, a technical change, an injury, or a season of doing the work will all move you off the curve, up or down, and the athletes coaches remember are exactly the ones who moved off it. Read the projection as the target you are already on pace for, not as a result you have earned. Enter fully automatic times only; a hand time is a different number, and the hand time to FAT converter fixes that first.

The records the curve is built from

Every anchor, exactly as USATF publishes it, with the implement or hurdle height the division competes with and the factor it produces. Between anchors the factor is a straight line.

Girls

The factor at every age

The factor for each age, and the age standard it implies (the open standard divided by the factor).

Curve: TrackReels curve derived from USATF championship meet records by age division. Records transcribed as published from USATF National Junior Olympic Track & Field Championships records, USATF U20 Outdoor Championships records, USATF Outdoor Championships records, retrieved 2026-09-09. This is TrackReels' own derivation, not a World Masters Athletics table and not an official standard of any body. Nothing on this page is estimated beyond the derivation described above.

What is still not here

The 300m hurdles, a high school race with no U20 or open championship record to anchor a curve on; the hammer and weight throws, which have no Junior Olympic division records; and the combined events. The site would rather leave those out than invent a curve for them. The published college standards cover every event the site ranks, and the hurdle specifications by level explain what changes with age for the hurdle races.
