How to run a faster 400

Fantastic time! Whatever you are doing as far as training goes, keep doing it, because it's working!!

You are so close. I think you can probably get there by improving your race execution just a little bit. The simplest thing to work on is staying as smooth, strong, and relaxed as you come out of the last turn. If you can hold pace and form over the last 100m, you'll get there. Really work at keeping your turnover high in that last 100m. It's a simple concept, but it's not easy. It's something you will need to focus and work on in every race.

If you think endurance needs work, then you'll probably benefit by racing some 800s.
