A 43 flat is approximately comparable to a 60 or 61 second 400 hurdle time. I ran a 39 300 and my fastest 400 time was 55. That last 100 in a 400 hurdles really really hurts.
In the 400 meter hurdle, there are 10 hurdles. Each hurdle is 30" tall with 35m between them. There is a 45m distance before the first hurdle and a 40m distance to the finish line from the last hurdle.

400 metre hurdle
There are 10 hurdles in the 400 meters hurdles race. Athletes must clear each hurdle as they sprint around the track.
The distance between 300 Hurdles (or 400 Hurdles) is 35 meters. The distance to the first hurdle (in high school races) is 45 meters and 10 meters from the last (8th) hurdle to the finish line. This is exactly the same as the first 300 meters of a 400 Hurdle race, though the relative position on the track is moved to finish at the common finish line.
