How to break 50 seconds in the 400 meters

There's a great site out there called SpeedEndurance.com that has a lot of great information on 400 meter training. They put up an article about how to break 50 seconds in the 400. The article is mostly about how to figure out if you can break 50 seconds based on how fast you can run shorter distances. I know that one of the keys to getting my 400 meter time down is to improve on my 200. That's been one of my goals this year. I'm currently trying to get it under 24 seconds. My fastest in a race was back in high school at 23.5. That's really not that fast. Since I converted to the 800 meters in college I never ran an open 200 meters.

I ran a 24.00 in my last meet this year so I'm hoping I can get under that at the National Championships in a couple of weeks. My chances of making the finals look pretty slim for the 200 so I'll likely only have one more try. I bring up the 200 time because one of the formulas on how fast you can run the 400 is to take your 200 time x 2 and add 4 seconds. Since I was fortunate enough to run exactly 24 seconds it's an easy formula for me. 24 x 2 is 28 + 4 = 52. I'm shooting to get under 53 seconds so at least I know that's a reasonable expectation.

Here is a video that sums up the article. There's some good information although I wish they would have included the 300 meter formulas as that's what I've been using for my training.

Since it's been so hot out lately I have adjusted my training slightly for this week. I was planning to run 4 x 200s with 65 seconds rest this week, but I think I will shift that workout to this weekend. I have been pushing pretty hard on the Asylum and P90X2 workouts so that should keep my cardio and strength up. The workout I did in place of the 200 meter workout on Tuesday was Asylum Vertical Plyo and I'm sure I got a great workout in so I don't feel like I missed out on anything. I'm also feeling like I should back off a little bit on the track workouts right now. My hamstrings and lower back have been pretty tight lately and need some time to recover.
