In college they get higher and at 5'9'' that didn't help. I still ran them but was "better" at the 400 hurdles, as most elite hurdlers seemed to focus on one event and chose the 110s bc the 400 was just a much harder race for them. I ran the 400 hurdles in highschool whereas most states ran 300 at that point so for me it wasn't an adjustment - race actually got easier over time.

I ran the 120HH and the 180LH in high school. (ran 14.8 and 19.6 - both school records). In college I ran a 14.6 and in the 400IH a 54.2.
I actually ran the HS highs in college and ran a 14.1...and still got beat by a guy that ran a 13.8 LOL
