As Track & Field season gets underway there will be an influx of running enthusiasts, who normally either only run for fun or to stay socially active, into the Track world. It's like January 1st for the gym except for the Track. However, the following technique to be explained in this post is aimed for everyone on the Track spectrum, be you the runner who thinks they can run a 5k for fun and then come on the track and try bust out a 2 minute 800m or the experienced track athlete looking for a new way to improve in their ability. I learnt this philosophy on training from the Cross Country/Track coaching staff at Glendale Community College in California and it has proved most beneficial to me: it is called "The Sandwich Technique".
This is not a detailed orientated training program, but more an overview on how to actually formulate training from this base point. As I myself strive to be a 400m runner I will explain the technique from that perspective. Here however, is an incredibly detail oriented training plan for the 400m runner from the official Coaches Association of the IAAF-NACAC .

A sandwich wouldn't be complete without the bread on either side of the filling, otherwise it wouldn't be a sandwich and just a pile of vegetables and meat. Those outer layers (bread) of the sandwich are essential to its being, and thus the same is true for the runner. As a 400m runner the vegetables and meat are the 400m; the bread on either side is the corresponding race on either side of the 400m, i.e the 200m and the 800m.
A 400m runner must have the speed of a 200m sprinter and the endurance of the 800m runner. So during your training you have to incorporate ingredients from both a 200m training program and an 800m one. Of course your main training focus will be on the 400m, but weekly portions of your training should include these factors. Even in the early stages of track season when the races are not very important you should use the sandwich technique by entering into races from the 200m, 400m and 800m (That doesn't mean all in one day, but well done if you do). You will get experience racing against unearthly quick 200m racers and the never-ending endurance of the 800m racers. This will allow you to combine all of this experience into your race, in which you are going to be confronted with aspects of both.
The sandwich technique is simply logical philosophy on an overall way to train and race. Take what you will from this and remember that every runner is different, so it may not work for you, but it doesn't hurt to give it a try.
Good luck to all!
