2. Introduction<br />

Coaching Hurdles<br />

Hurdling is a sprint event. To be successful in a <strong>hurdle</strong> race the athlete must<br />

first be successful as a sprinter. However there are distinct differences<br />

between the requirements of a sprinter and the requirements of a <strong>hurdle</strong>r.<br />

How many world class sprinters are world class <strong>hurdle</strong>rs, or vice versa?<br />

A sprinter, put simply, has a specific distance to cover in a short a time as<br />

possible. The sprinter has complete freedom on stride length and frequency<br />

and no specific demands on flexibility or rhythm.<br />

The <strong>hurdle</strong>r, like the sprinter, has to cover a specific distance in a short a time<br />

as possible however on the way has to negotiate several barriers as efficiently<br />

as possible minimising any loss of speed. This places specific demands on<br />

the <strong>hurdle</strong> athlete in terms of flexibility (low <strong>hurdle</strong> clearance) and stride<br />

pattern (rhythm).<br />

In essence the critical success factors <strong>for</strong> a Hurdler can be summarised as:<br />

Hurdle Efficiency and Stride Cadence.<br />

Hurdle Efficiency -. The basic aim of the <strong>hurdle</strong> action is to get off the ground<br />

and get back on the ground as quickly as possible with as minimum disruption<br />

(loss of speed and technique) to the regular sprint style as possible.<br />

This means a minimum <strong>hurdle</strong> clearance which in turn places demands on the<br />

<strong>athletes</strong> flexibility.<br />

Stride Cadence - Take an 80m <strong>hurdle</strong> race <strong>for</strong> example. The first <strong>hurdle</strong> is<br />

12m from the start, there are 9 <strong>hurdle</strong>s each 7m apart and the last <strong>hurdle</strong> is<br />

12m from the finish line. Almost without exception the required stride pattern<br />

<strong>for</strong> success in this event is 8 strides to the first <strong>hurdle</strong>, 3 strides between the 9<br />

Hurdles (24 strides) and 7 to the finish line, a total of 39 strides.<br />

The athlete that can complete the 39 strides the quickest will win the race.<br />

Stride length there<strong>for</strong>e is not an important attribute <strong>for</strong> the <strong>hurdle</strong> athlete as<br />

this is dictated by the position of the <strong>hurdle</strong>s. Stride cadence (speed or<br />

frequency) is the second key attribute <strong>for</strong> the successful <strong>hurdle</strong> athlete.<br />

This manual aims at providing a sequence of skill acquisition, coupled with<br />

drills and exercises that assist in <strong>coaching</strong> a novice <strong>hurdle</strong>r to becoming an<br />

accomplished <strong>hurdle</strong>r.<br />

Photos are used extensively throughout the manual as a way of showing the<br />

action under discussion or the setup/apparatus required to per<strong>for</strong>m the action<br />

however they should be viewed in context with the descriptive text<br />

accompanying the photo.<br />

Trail Leg<br />

Figure 9 – Hurdle Sequence<br />

Coaching Hurdles<br />

The trail leg should remain ‘compact’ – short levers move much faster than<br />

long levers - with the heel of the trail foot close to the athlete’s bottom. The<br />

lower trail leg (knee to foot) should be basically flat over the <strong>hurdle</strong> with the<br />

trail foot slightly below the trail knee. The trail foot should be dorsiflexed.<br />

The trail knee continues to rise after clearing the <strong>hurdle</strong> and will almost<br />

touch the athlete’s chest. The trail leg, after clearing the <strong>hurdle</strong>, should<br />

return to the front of the athlete.<br />

Referring to Figure 9 – Hurdle Sequence the action of the trailing leg:<br />

• The trailing leg drives the body at the <strong>hurdle</strong> as the lead leg rises [5, 6].<br />

• The recovery of the trail leg must begin from well behind the body if the<br />

drive is to be completed.<br />

• The athlete should feel the trailing knee sweeping wide and flat over the<br />

<strong>hurdle</strong> [6, 7].<br />

• As the leg crosses the <strong>hurdle</strong> the foot must be cocked (dorsiflexed) at<br />

the ankle so that the foot does not hit the barrier [9, 10].<br />

• After crossing the barrier the knee continues to rise and comes round in<br />

front of the body [10, 11, and 12].<br />

• Many young <strong>athletes</strong> have a tendency to drop the trail leg off to the side<br />

after it has crossed the barrier. This has the effect of making the first<br />

stride very short and pulling the athlete off balance. The trail leg must<br />

be pulled through high and fast so that the first stride is fast [12, 13,<br />

and 14].<br />

The trail knee is always higher than<br />

trail foot. The trail foot remains<br />

dorsiflex throughout motion.<br />

The athlete aims to pull the trail leg<br />

through as quickly as possible.<br />

The trail foot stays close to <strong>hurdle</strong><br />

whereas the trail knee will continue to<br />

rise after clearing the <strong>hurdle</strong>.<br />

This position is often likened to a dog<br />

taking a leak.<br />

Figure 10 – Trail leg position, Knee/Foot relationship<br />

Figure 11 – Trail leg position, high knee<br />

The trail leg rotation completes with<br />

the trail leg in front of athlete and<br />

knees high as in sprint motion. As I<br />

the ‘B’ skip the lower leg then extends<br />

and the foot strikes the ground while<br />

travelling backwards.<br />

Page 14 of 106


Figure 12 – Trail leg position, in front<br />

Coaching Hurdles<br />

Trail leg plant comes from a vertical<br />

‘in front’ position.<br />

The trail leg action can be best taught by breaking the action down into 5<br />

stages as shown above. The stages are (1) the trail leg is lifted off the track<br />

but remains straight, as in the push off from the previous stride, (2) the trail leg<br />

foot is everted and dorsiflex, (3) the trail knee is pulled through to the side,<br />

trail foot remains below the knee, (4) trail knee is pulled to a ‘vertically in front’<br />

position, note high knee, (5) trail foot actively returns to the track while<br />

travelling backwards (like in the ‘B’ skip).<br />

Have the athlete sequence through the 5 stages pausing at each stage to<br />

check correct position. Gradually reduce the pause until the action becomes a<br />

continuous fluid motion.<br />

Figure 13 – 5 Stages of Trail Leg Action<br />

Coaching Hurdles<br />

Next are several exercises that assist the athlete to develop a constant Centre<br />

of Gravity over the <strong>hurdle</strong>.<br />

‘The Hedgehog’<br />

Here the athlete is using a ‘hedgehog’<br />

to gauge clearance over the <strong>hurdle</strong>.<br />

The hedgehog is simply a <strong>hurdle</strong> that<br />

has 150mm long flexible plastic<br />

fingers protruding from the top edge.<br />

The athlete is aiming to pass the lead<br />

foot through the fingers.<br />

When successful the athlete can feel<br />

the fingers and gain the positive<br />

feedback on their hurdling height.<br />

The athlete in the photo is only just<br />

skimming the top of the fingers and<br />

should lower her action to improve<br />

<strong>hurdle</strong> speed.<br />

Figure 19 - Feedback on trail leg height using ‘Hedgehog’<br />

The hedgehog in use again here to<br />

gauge the height of the trail foot.<br />

The athlete is aiming to pass the trail<br />

foot through the fingers.<br />

When successful the athlete can feel<br />

the fingers and gain the positive<br />

feedback.<br />

Spider Drill<br />

Figure 33 – Spider drill<br />

Coaching Hurdles<br />

Similar to the Walkover Drill the<br />

Spider Drill aims at developing the<br />

athlete’s awareness and coordination<br />

of the lower limbs while hurdling.<br />

The <strong>hurdle</strong>s are set close together<br />

(around 0.5m) and slightly lower than<br />

normal so that the athlete can<br />

com<strong>for</strong>tably straddle the <strong>hurdle</strong>.<br />

The athlete steps over each <strong>hurdle</strong> in<br />

turn with only 1 foot touching the track<br />

between <strong>hurdle</strong>s.<br />

Each leg per<strong>for</strong>ms a trail leg<br />

movement.<br />

For variation have the athlete per<strong>for</strong>m<br />

this drill backwards.<br />

This same drill can be per<strong>for</strong>med<br />

while carrying a Medicine Ball high<br />

above the <strong>athletes</strong> head. This<br />

heightens the awareness of the<br />

shoulders and promotes a feeling of<br />

high hips and feeling tall.<br />

A further progression can be achieved<br />

by increasing the space between<br />

<strong>hurdle</strong>s requiring the athlete to add a<br />

small skip in order to reach the next<br />

<strong>hurdle</strong>.<br />

Emphasis in all variations of this drill<br />

is to keep the hips square to the<br />

direction of travel as much as possible<br />

i.e. do not let the hips turn sideways<br />

as the athlete negotiates the <strong>hurdle</strong>.<br />

Figure 35 – ‘20/20’ Drill<br />

Coaching Hurdles<br />

‘20/20’ Drill<br />

Cones are placed on<br />

the track 40m apart. In<br />

the middle, two <strong>hurdle</strong>s<br />

are placed in adjacent<br />

lanes facing the<br />

opposite way to each<br />

other.<br />

The athlete is required<br />

to set off from one<br />

cone, <strong>hurdle</strong> the <strong>hurdle</strong><br />

in the lane, continue to<br />

the second cone, turn<br />

around move, to the<br />

adjacent lane and<br />

repeat.<br />

This drill is aimed at<br />

developing ‘Spatial<br />

Awareness’ required <strong>for</strong><br />

the 200, 300, 400m<br />

<strong>hurdle</strong> athlete who<br />

need to be able to<br />

judge distance and<br />

timing to the <strong>hurdle</strong>s.<br />

Repeat while moving<br />

the cones and/or<br />

<strong>hurdle</strong>s +/- 1m between<br />

rotations<br />

For sprint <strong>hurdle</strong>rs this<br />

same drill can be<br />

per<strong>for</strong>med with 2, 3 or<br />

even 4 <strong>hurdle</strong>s in<br />

adjacent lanes – in this<br />

example the <strong>hurdle</strong>s<br />

would be placed on the<br />

correct spacing <strong>for</strong> the<br />

event. See Figure 54 –<br />

3 Hurdle Turnaround<br />

Coaching Hurdles<br />

Hurdle and cones are set out as shown below. The ‘Run In’ distance and<br />

distance between <strong>hurdle</strong>s should be as <strong>for</strong> the event specification. The<br />

example below is <strong>for</strong> the 80mH.<br />

This exercise compresses the normal <strong>hurdle</strong> distance into half and includes<br />

twice as many acceleration phases. Primarily it is an Acceleration exercise<br />

however if repeated can also act as an endurance exercise.<br />

Start with 4 rotations per set with a short, say 30sec rest, between rotations.<br />

Repeat 2 or 3 times or until the athlete lose <strong>for</strong>m.<br />

This same drill can be per<strong>for</strong>med with 1 to 4 <strong>hurdle</strong>s in each direction.<br />

Circular Sprint Hurdle<br />

Figure 54 – 3 Hurdle Turnaround<br />

Hurdles are set out as shown below. The <strong>hurdle</strong>s should be placed on the<br />

correct marks <strong>for</strong> the event. Height should be 1 height below normal<br />

competition (68cm <strong>for</strong> 76cm competition).<br />

The ‘run’ phases are per<strong>for</strong>med near 100%. The walk phases are <strong>for</strong> recovery<br />

hence per<strong>for</strong>med at a slow walking pace.<br />

This exercise provides 2 acceleration and 2 top speed units per rotation. It<br />

also assists develop spatial awareness by having the larger than normal gap<br />

between the first and second <strong>hurdle</strong> grouping. However if repeated several<br />

times can also act as an endurance exercise.<br />

Start with 2 rotations per set with a short, say 2 min rest, between rotations.<br />

Repeat 2 or 3 times or until the athlete lose <strong>for</strong>m.<br />

This same drill can be per<strong>for</strong>med with a variety of <strong>hurdle</strong> combinations (1+1,<br />

2+2, 1+1+1, 2+1+2…) to keep the exercise interesting. The example below is<br />

a 100mH 2+2 variation.<br />

Coaching Hurdles<br />

Over Under<br />

A good warm up<br />

stretching exercise<br />

targeting the adductors.<br />

4-6 <strong>hurdle</strong>s are<br />

arranged approx 1m<br />

apart. Hurdle height<br />

alternate from a low to<br />

height setting. In the<br />

photo example from<br />

68cm to 76cm (adjust<br />

depending on the<br />

height of the athlete).<br />

The athlete walks to the<br />

first <strong>hurdle</strong> and<br />

per<strong>for</strong>ms the normal<br />

lead leg action over the<br />

<strong>hurdle</strong>.<br />

The lead leg clears the<br />

<strong>hurdle</strong> and touches<br />

down on the exit site.<br />

The trail leg is pulled<br />

through and fed under<br />

the next <strong>hurdle</strong>.<br />

The athlete then<br />

crouches under the<br />

<strong>hurdle</strong> pulling the lead<br />

leg through and over<br />

the next <strong>hurdle</strong>.<br />

The athlete continues<br />

to the end of the<br />

<strong>hurdle</strong>s<br />

The athlete should<br />

per<strong>for</strong>m the same drill<br />

alternating the initial<br />

lead leg.<br />

Note only 1 foot contact<br />

between each <strong>hurdle</strong>.<br />

Page 66 of 106


While in the seated <strong>hurdle</strong> position have the athlete<br />

per<strong>for</strong>m the arm actions as if in a sprint <strong>hurdle</strong> race. That is<br />

swinging the arms as if running. The lead arm reaches <strong>for</strong><br />

lead foot as the trail arm remain compact. Count 1, 2, 3 as<br />

the arms swing in a normal running action then repeat the<br />

lead arm reach. The athlete’s upper body should lean<br />

<strong>for</strong>ward with the lead arm reach.<br />

Repeat 10x then change legs and repeat.<br />

Figure 80 – Seated leg stretch<br />

Coaching Hurdles<br />

Seated Leg Grab<br />

The athlete sits on the<br />

track in the <strong>hurdle</strong><br />

position (lead leg<br />

straight in front, trail leg<br />

to side, heel to bottom).<br />

The athlete leans<br />

<strong>for</strong>ward and grabs the<br />

lead foot with both<br />

hands and holds the<br />

position <strong>for</strong> 5-10<br />

seconds and repeats.<br />

Aim to get the athlete’s<br />

chest as low as they<br />

can if possible touching<br />

their upper leg (head<br />

touching knee).<br />

Repeat several times<br />

<strong>for</strong> both legs.<br />

Where the athlete is<br />

unable to reach their<br />

toes, hold as far down<br />

the leg as possible.<br />

There should be no<br />

bouncing. The<br />

important thing is to<br />

‘hold’ the position.<br />

Progress to have the<br />

athlete lean over the<br />

Trail leg and again try<br />

to get as low as<br />

possible.<br />

Lastly have the athlete<br />

lean between the Lead<br />

and Train and try to get<br />

their head as close to<br />

the track as possible.<br />

7. Distance Hurdle Races<br />

Coaching Hurdles<br />

While in principle the basic <strong>hurdle</strong> technique remains the same regardless of<br />

the race distance, the distance <strong>hurdle</strong> races (200m, 300m & 400m) require a<br />

slightly different approach.<br />

As the race is much longer the athlete needs to develop the ability to maintain<br />

speed over the longer distances. It is unusual <strong>for</strong> an athlete to be able to<br />

maintain a regular stride pattern over the full race distance and the athlete<br />

should develop a race plan <strong>for</strong> when this ‘change down’ in strides will occur.<br />

However the athlete also needs to be able to adapt to the prevailing<br />

conditions on race day. Wind strength and direction in particular can dictate<br />

when the athlete has to modify their plan.<br />

A factor that can help an athlete overcome the stride pattern variation,<br />

between <strong>hurdle</strong>s is the ability to <strong>hurdle</strong> with both legs. An athlete’s <strong>hurdle</strong><br />

technique may not be as good with the non preferred leg but it is essential if<br />

the athlete is to avoid hesitation (stuttering) at the <strong>hurdle</strong>.<br />

As the longer <strong>hurdle</strong> races obviously involve hurdling on the bends a left leg<br />

lead can provide some advantage. On the corner the athlete will lean slightly<br />

to the inside of the track (left) to counteract the centrifugal <strong>for</strong>ces pushing<br />

them wide. The right trail leg there<strong>for</strong>e has a greater space with which to<br />

complete its action. Also by leading with the left leg the athlete is able to stay<br />

close to the inside line.<br />

A right leg lead will tend to push the athlete wide of the lane (after the <strong>hurdle</strong>)<br />

hence adding distance to the race. Also a right leg lead requires the left trail<br />

leg to complete its action while slightly under the leaning body of the athlete –<br />

to compensate a right leg lead <strong>athletes</strong> will often run wide in the approach to<br />

the <strong>hurdle</strong> so as to attach the <strong>hurdle</strong> ‘straight on’<br />

In order to maximise the left leg lead advantage however care needs to be<br />

taken on the placement of the lead leg on landing. Ideally the left leg lead<br />

should land on the left of centre of the lane. Otherwise the athlete will run wide<br />

in the lane and be off balance. To make this happen the athlete need to push<br />

their right arm and hips to the left while negotiating the <strong>hurdle</strong>.<br />

As a <strong>guide</strong> to <strong>hurdle</strong> efficiency and per<strong>for</strong>mance, an athlete’s 400mH time will<br />

be approximately 4 seconds greater than their 400m flat time.<br />

Cumulative Speed (m/s)<br />

Interval Speed (m/s)<br />

With the longer <strong>hurdle</strong>s top speed is achieved at H1 due to the much longer<br />

run in (45m <strong>for</strong> the 400mH). Also as a consequence of the longer distance the<br />

rate of decay is greater. The dash to the finish is also longer and usually<br />

facilitates a slightly higher speed finish.<br />

Distance Hurdle Exercises<br />

Alternate <strong>hurdle</strong> pyramid<br />

Coaching Hurdles<br />

This is a good exercise <strong>for</strong> the 200m (10 <strong>hurdle</strong>) event. 68cm <strong>hurdle</strong>s are set<br />

on the 200mH H1 to H7. All runs commence from a standing start and are<br />

completed at slightly sub maximum speed. This is largely a speed endurance<br />

exercise but has elements of acceleration and top speed. One set consists of<br />

7 runs as described below. 2 sets are quite demanding and should only<br />

continue as long as correct <strong>hurdle</strong> <strong>for</strong>m can be maintained.<br />

Figure 91 – 200m Pyramid<br />

1 st run – to H1, walk back to start<br />

2 nd run – to H3, walk back to start<br />

3 rd run – to H5, walk back to start<br />

4 th run – to H7, walk back to start<br />

5 th run – to H5, walk back to start<br />

6t h run – to H3, walk back to start<br />

7 th run – to H1, walk back to start<br />

Only minimal rest between runs.<br />

As a progression include all <strong>hurdle</strong>s rather than every other <strong>hurdle</strong>: H1, H2,<br />

H3, H4, H5, H6, H7, H6, H5, H4, H3, H2, H1<br />

8. Common Errors and How to Correct<br />

Coaching Hurdles<br />

This section will attempt to address some common problems found in the<br />

sprint <strong>hurdle</strong>s and suggest possible reasons and corrections.<br />

• Problem - Too far from the first <strong>hurdle</strong><br />

• Possible Cause - Sprint strides during initial acceleration from<br />

blocks are too short. Blocks may be set too close together<br />

resulting in too short of an initial stride. Arm action in<br />

acceleration to first <strong>hurdle</strong> may be too passive.<br />

• Correction/Solution - Develop <strong>athletes</strong> contractive strength<br />

required to drive from the blocks with sufficient stride length to<br />

make the 12m distance in 8 steps. Move blocks to medium<br />

spacing and check body angles in start position. Lengthen arm<br />

action and increase the amplitude of arm movement.<br />

• Problem - Too high over the first <strong>hurdle</strong><br />

• Possible Cause - Athlete is too close to the <strong>hurdle</strong> at takeoff.<br />

Takeoff foot planted on heel. Non-existent or non-active cut<br />

step. Lead leg not folded tightly until thigh reached parallel or<br />

above. Athlete afraid of <strong>hurdle</strong>.<br />

• Correction/Solution - Keep athlete in sprint acceleration posture<br />

longer. This will keep strides shorter and help the athlete attain a<br />

higher velocity. Make sure the athlete is accelerating in a pattern<br />

of acceleration and not overstriding. If the athlete is planting their<br />

takeoff foot like a long jumper this will make the last stride be<strong>for</strong>e<br />

the <strong>hurdle</strong> too long and result in placement too close to the<br />

<strong>hurdle</strong>. Practice a tall posture, making the cut step active and on<br />

the front of the takeoff foot. Rehearse proper lead leg mechanics<br />

and body posture going into <strong>hurdle</strong>. Also examine what the<br />

takeoff foot is doing. If it is planted on the heel than the lead leg<br />

will tend to open up too soon. Use <strong>hurdle</strong>s in practice that are<br />

constructed of soft, flexible materials or constructed to be<br />

<strong>for</strong>giving. If the <strong>hurdle</strong> is not a threat to life and limb, the athlete<br />

will gain the necessary confidence to run through the <strong>hurdle</strong> with<br />

the velocity necessary to per<strong>for</strong>m efficient technique.<br />

• Problem - Off balance coming off the <strong>hurdle</strong><br />

• Possible Cause - Lead leg and opposite arm are driven<br />

inward/outward and not parallel to the direction of travel.<br />

• Correction/Solution - Have athlete work on keeping the lead leg<br />

mechanics as described above so as to enable the athlete to<br />

more easily keep their actions in line with the direction of the<br />

run. Use sprint arm action into the <strong>hurdle</strong> and not across the<br />

body. Also, the athlete may be too close to the <strong>hurdle</strong>.<br />

• Problem - ‘Jump’ <strong>hurdle</strong>s<br />

• Possible Cause - Athlete may not have flexibility to ‘flatten out’<br />

over <strong>hurdle</strong>. Lower trail leg not flat over <strong>hurdle</strong>. Taking off too<br />

close to <strong>hurdle</strong>.<br />
