Girls run the same 100 meter hurdle race in high school, in the NCAA, and in the Olympic final. Same 33 inch barriers. Same 13 meters to the first hurdle, same 8.5 meters between the rest. That is unusual in track, and it means a high school girl's time compares directly to a national record or an NCAA final with no conversion in between. Below: the ladder by grade, published state entry standards, and where the national-class line actually sits.
Thirty three inch barriers, 13 meters to hurdle one, 8.5 meters between each of the ten, and 10.5 meters from the last one to the line. High school, NCAA, and World Athletics all use the same layout. Junior high girls race the same distance over 30 inch hurdles, and that is the only step down you will meet. The heights for every other hurdle event are in hurdle height by event and age.
The 8.5 meter spacing is set so a grown woman can cover it in three strides. A shorter or younger athlete who cannot get there yet runs four and alternates lead legs, which costs a couple of tenths at every barrier. Reaching a clean three step is usually worth more than any amount of extra flat speed. Benchmarks across all three hurdle events sit in average hurdle times by age.
Plenty of 12.6 sprinters run 17 second hurdles, and plenty of 13.2 sprinters run 15.5. Across ten barriers the time you lose in the air swamps the time you gain on the ground. Worth knowing before you decide you are too slow for the event. Where your flat speed sits is easy to read off the 100m ranges for high school girls.
Most girls lose the race at hurdles one, two, and eight rather than in the middle. Film one full run from the side and the AI grades takeoff distance and clearance height at every barrier, so you can see where the time is actually going.
