U could be right, I haven't raced a 400 in spikes in a long time, its also that I hate sprinting.
I think people would be surprised at how easy it is to become fast. Sadly, most people think that sprinters are only people who are naturally fast, but what it takes is excellent mechanics (and good knowledge).
For example, the foot strikes of the average distance runner stay in contact with the ground many times longer than those of a sprinter. In a sprint, ground contact beyond what is absolutely needed to move forward will slow you down. Foot strikes should be more of a
pop than a
thud.
Additionally, to make sure that you accomplish the proper foot strikes, sprinters should be running a couple inches taller than their standing height. Once you transition out of your drive phase in a sprint, you should move into a position were you feel like you are almost floating above the ground.
Another thing that people overlook is the vital part that arms play in sprinting. Not only can arm movement help speed up leg movement, your arms can also help you maintain your floating position. Driving the arms up (in both the forward and backward parts of the swing) can help with lift, this means that more of the energy from foot strikes can be used for pushing you forward rather than just keeping you up. It is also important to open up the arm swing so that while swinging forward you are punching through the height of your center of mass (for most athletes this would be at about hip level).
Arm movement technique is so important that when I was coaching I had my athletes stand in place and practice just arms. Beyond letting me see their technique up close, it also helped them feel what good arm technique can do. Just standing and doing proper arm movement, most athletes can feel the upward force that they get from it. It also helped to get them to show up for weight workouts once they could actually understand how important the upper body is for sprinting.
The float position is even more important for the longer events like the 400, 400 hurdles and 800. When done right, it takes less effort to maintain speed while floating... specially on the straightaways. In those races, the key upper body muscles are across the upper back, and I designed weight workouts for my athletes to help keep the
bear on the last turn from jumping on their backs.
And all that was especially important for me in my main event, the 110 meter high hurdles, because in addition to needing the float to run fast, the extra couple inches helped put me into a better position for attacking the hurdles. Being neither naturally fast nor all that tall (I'm 5'11", which is on the short side for someone who sprints over 42" barriers), I used perfect sprint technique and hurdle form to make up for what nature left out.
I was also lucky enough to have one of the best sprint/hurdle coaches in the world ask me to start working out with him after my sophomore year in high school. In the high hurdles I ran 16.2 my freshmen year, 15.7 my sophomore year, 14.72 (and 14.6 hand timed) my junior year and 14.88 my senior year (following ankle surgery). My first year running college high hurdles I dropped down to 14.64 (and also ran 10.8 in the 100 and 22.3 in the 200 that year).
While those aren't exactly incredible times, considering that they were run by someone with only average natural abilities is what sets them apart.
