Hurdle times split the field harder than flat sprints. Hurdle clearance is technical, so a mediocre 100m sprinter with clean hurdling outruns a faster sprinter with sloppy form. The benchmarks below come from NFHS state results, NCAA regional cutoffs, and World Athletics rankings. Use them to find your gap honestly.
Adding 10 barriers to a 100m flat usually adds 1.5 to 2.5 seconds. A 12.5 sprinter who hurdles cleanly runs around 14.0-14.5; a 12.5 sprinter who fights every barrier runs 15.5+. Barrier height drives most of that spread, which is why the 110m hurdle ladder for high school boys names a height on every row.
The 3-step rhythm between barriers is the main constraint. If you cannot 3-step the standard spacing at your event height, you are running a slower race regardless of flat speed. The 100m hurdle marks for high school girls are built around exactly that problem.
The 400m hurdles is more about lactate tolerance and stride pattern across barriers than pure hurdle technique. The benchmarks below split it out. Most American high schoolers meet the event as the 300 instead, and the two are set side by side in 300m hurdles versus 400m hurdles. The long hurdles carry their own age ladder, with the barrier height on every row, in 400m hurdle times by age.
Hurdle time is a function of clearance height, lead-leg snap, and stride pattern. Film a hurdle rep, AI grades all three. Same model, different standards by event.
