A boys' 1:00.00 400m hurdles at 16 projects to 57.92 at 18; a girls' 1:11.00 400m hurdles at 16 projects to 1:10.28 at 18 on the TrackReels curve derived from USATF age-division records.
Enter your current age and your best fully automatic 400m 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 16 and up: the youngest division with a published record).
Enter your age and your best mark (fully automatic timing for a race), and the table shows the same level on the curve at every age up to 30.
Four starting points, boys then girls, carried forward on the same curve. The curve starts at 16, the youngest age with a published record for this event, so the ladder starts there.

|---|---|---|---|---|---|
| 56.00 | 55.01 | 54.06 | 53.14 | 52.03 | Inside the published NCAA Division I recruiting range. |

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.
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.
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.

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.
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.
