I’ve seen people run decent just on natural ability alone….it’s tough to make estimates on something like this because there are so many factors at play (coaching, training, your own abilities, etc.).
exactly what mike said. my first 110 race was a 19.5, though my younger rival ran a 17.3 his first try. the next year i ran a 16.9, and after that a 15.7. but my teammate doesnt make such radical jumps in times as i do, so far his best is only 2 tenths ahead of mine.
Lets see I went from low 20’s freshman year in the 110HH to high 15’s senior year. I gotta say I didn’t really train hard in high school compared to college but I improved and had fun. I also saw people who just had a week of practice run the hurdles in 17’s.
Also, a lot of it has to do with physical maturity. When your body is physically able to handle hurdling, you’ll see your times drop. But i definitely agree with mike. You could hurdle really well on talent alone, and you might train all year and still not hurdle very well. it depends so much on coaching and ability.
