Track: Drill to Keep the Trail-Leg Tight Over the Hurdle

An important element of good hurdle technique is a compact trail leg over the barrier. That is, the heel of the trail leg should be kept tight to the buttocks as it crosses the hurdle.
If it's allowed to extend as it crosses, it increases the length of the lever that must be moved forward. This is basic physics: with the same amount of force, a longer lever moves more slowly.
An extended trail leg may also produce a counter-action from other areas of the body: possibly lateral body lean, and/or a high trail-leg arm. And, in certain circumstances, an extended trail leg might even infringe on an inside lane, causing disqualification.

1. Place Instep of Trail-Leg on Top Edge of Hurdle
Here's a drill that will teach your students the correct position of the trail-leg heel as it crosses the hurdle.
Setup
Have your students lean against a wall. Place a hurdle sideways beside each student and have them place the instep of their trail leg on top of the hurdle.
Instruct them to pull the trail leg forward, dragging their instep along the hurdle. They continue pulling forward, finishing with a high knee in front of the body. They then perform more repetitions of the movement.

In my experience, the best hurdles to perform this drill are steeplechase barrieirs - they have a wide, flat surface and a solid base that make the drill more effective.
This drill forces good trail leg mechanics: heel tight to the buttocks, and knee pulled beneath the armpit. And it's a great specific flexibility exercise for the trail leg.
Variation
To develop extra flexibility, angle the hurdle so the front is higher than the back. This forces an even higher pull of the knee beneath the armpit.
