Sprinting – why short to long could be better than long to short!

Most sprint athletes tend to use a 'long to short' training approach, where they perform slower aerobic and anaerobic work at the beginning of the training year and then progress to faster and faster anaerobic work as the season approaches and during the season itself. However, it doesn't have to be this way; some coaches believe that that this methodology is not only outdated but also that by turning convention on its head and using a 'short to long approach', better results can be achieved.

The short to long approach emphasises speed through the year with athletes performing sprint training right from the beginning of the season. Proponents of this approach (such as Charlie Francis, the coach of ex-100m world record holder Ben Johnson) claim it can enhance speed development, allow for more 'speed peaks' through the season and reduce injuries that often occur when sprinters try to pick up the pace from their early season slow pace training.

Aerobic conditioning

Because aerobic conditioning serves as a 'base conditioning' for health and fitness, it has formed the core of training programs for a number of different sports, including those where sprinting is the main type of activity. However, take a look at the actual volume of aerobic work performed by sprint athletes and sportsmen and you'll see it's very low indeed. Not only may time be spent training an energy system that will hardly be used, the slower pace of training can also serve to blunt the speed and power output in the fast twitch muscles that are required for sprinting.

Short to long proponents like Charlie Francis recommend that experienced runners from 100-400m need only spend a short 6-week period at the start of the season performing training with an aerobic element, and even then, it shouldn't be long, slow runs but instead based on sets of short distance tempo runs of 100-300m performed at around 75% maximum speed.

Intensity is the key for maximum sprint performance

The short to long approach emphasises intensity throughout the year; a steady increase in training volume is not required or recommended – indeed volume may even decrease. This allows an athlete to remain close to his or her peak sprinting condition through the season, which in turn means that multiple peaks are possible through the season. The role of the coach is to try and successfully combine all the elements of perfect sprint performance (acceleration, absolute speed and speed endurance) seamlessly into these peaks, while simultaneously monitoring athletes to ensure adequate recovery is occurring and injury risk is minimised.

The maintenance of power throughout the season is also important. Charlie Francis for example advocates that workouts to develop power such as maximum strength workouts in the gym should accompany all phases of the training. The exception to this however is during the maximum sprint-speed training phase, where the addition of maximum weight workouts could overload the athlete and produce burnout. He prefers instead to combine plyometrics and fast sprinting to produce maximal power.

Blending sprinting speeds

The short to long approach advocates using a blend of sprint speeds to achieve and maintain maximum sprint condition throughout the year. The sprint speeds recommended are between 75% and 105% of maximum sprint speed (NB – 105% sprint speed refers to assisted 'overspeed' training techniques such as downhill running or bungee chords). Examples of these are shown in the table below:

Speed Type


Typical workout

Tempo runs

100-300m distances on the track run at 75-85% of maximum speed


6 x 200m at 75% effort concentrating on form with 5 minutes recovery between each run

Speed-endurance speed

Intense sprints over 60-120m designed to improve the ability to maintain flat out speed.

2 x 120m 100% sprints - full recovery

95% effort speed

Run at just below flat out speed designed to develop flawless technique without over-stressing the athlete

3 x 120m each with 7mins recovery in between

Out and out speed

Very intense runs performed at 100% effort

Sets of 4 x 40m sprints using blocks with a full recovery between runs

Over-speed speed

Performed at 105% of top speed using overspeed methods

4 x 30 m downhill runs, each with full recovery in between


Training for speed-endurance

Reaching top speed is one thing. Being able to maintain top speed is another. Developing speed endurance enables an athlete to carry his or her speed for longer without fading and is therefore crucial – eg for a 200m athlete to maintain top speed down the home straight. The amount of speed-endurance training required will depend on the nature of the sport and the role in that sport. For example, a football midfielder needs more speed endurance than a goalkeeper who may have to occasionally sprint, but only for very short distances.

A typical speed endurance workout for example might involve something like 5 sets of [sprint 20m, jog 20m, sprint 20m, walk 20m]. In the context of the short to long approach to sprinting however, the important thing to note is that speed-endurance training can and does blend seamlessly with the type of training an athlete will be performing anyway. For a full discussion and for detailed examples of speed-endurance workouts, readers are directed to George Dintiman's 'Sports Speed' (Dintimen G - Sports Speed, 3rd edition, Human Kinetics 2002), which provides an excellent treatment of this topic.


The key to the short to long approach is that it continually emphasises the need to move at maximum speed and to this end it strips out any training approaches that could be detrimental to achieving this goal. It is also very carefully constructed to allow the athlete to optimally adapt and recover.
