Sprinting Techniques: How to Start Faster, Accelerate, and Finish Strong

The sprint start from blocks is one of the most technically precise skills in athletics. Block settings vary by athlete based on leg length and individual mechanics, but the general principle is that the front block is positioned closer to the line to allow a powerful push from the stronger leg, while the rear block is set further back to create a longer drive surface. In the set position, the hips should rise slightly above shoulder height, the arms should be straight and shoulder-width apart with weight forward over the hands, and the body should be loaded like a compressed spring ready to release. A poorly set position where the hips are too high or too low will compromise the direction and power of the first stride before the athlete has even left the blocks.

The drive phase immediately after the gun covers the first 10 to 30 metres of a sprint and is where acceleration is established. The body angle during this phase should be low, with the torso leaning sharply forward and the first strides pushing back and down into the track rather than pulling the knees up immediately. Many sprinters, particularly those new to block starts, raise their torso too early, which shifts their momentum upward rather than forward and wastes the first several strides. Elite sprinters typically do not reach a fully upright posture until 30 to 40 metres into the race, by which point the drive phase has created a powerful base of speed to build upon.

The acceleration phase follows the drive phase and continues until the athlete approaches maximum velocity, typically between 40 and 60 metres in a 100-metre race. During this phase, stride length and stride frequency both increase progressively. Stride length increases as the body angle rises and the hip extension of each push-off becomes more powerful. Stride frequency is driven by the arm speed, which is why coaches consistently focus on arm mechanics during acceleration work. A faster, more compact arm drive directly increases leg turnover through the cross-pattern neurological link between upper and lower limbs.

A common error during the acceleration phase is trying to run fast before sufficient speed has been built through proper mechanics. Athletes who consciously chase speed too early tighten their shoulders, shorten their arm drive, and reduce their stride length, all of which slow them down relative to what relaxed, mechanically correct acceleration would produce. The paradox of sprinting is that relaxation produces speed more reliably than effort does, particularly in the transition from drive phase to full acceleration. Sprinters who want a complete reference point for how acceleration technique connects to the wider context of track athletics, including training methods and competition formats, will find everything organised in one place through the athletics guide on Effort Does It.

Maximum velocity is reached somewhere between 50 and 70 metres in a 100-metre sprint for most trained athletes, and maintaining it for as long as possible is the central technical challenge of the race. At maximum velocity, the key mechanical priorities shift from the aggressive forward lean and ground-pushing of the drive phase to an upright posture, high knee lift, and rapid foot cycling. The foot should strike the ground beneath the hips rather than ahead of them, and the contact phase should be as brief as possible. Elastic energy stored in the calf and Achilles tendon during ground contact is released into the next stride, and a stiff, springy ankle at contact maximises this energy return.

The most common mechanical error at maximum velocity is a collapse in posture: the hips drop, the head pitches forward, and the stride loses its elasticity as muscular fatigue accumulates. Athletes who maintain posture and hip height under fatigue decelerate more slowly than those who lose form, which is why core and hip strength training is directly relevant to sprint performance even though it does not feel like sprint training. Sprinters looking to build their technical understanding across all aspects of track performance, including start mechanics, acceleration drills, and velocity maintenance exercises, can explore the athletics skills & techniques guide on Effort Does It, which covers event-specific technique articles for both track and field disciplines.

The final phase of a sprint begins roughly 20 to 30 metres from the finish line and is where most races are decided between athletes of similar ability. Deceleration is inevitable in this phase for all sprinters as the neuromuscular system begins to fatigue, but athletes who have trained speed endurance, the ability to maintain mechanics under fatigue, decelerate more slowly than those who have not. Speed endurance is developed through training runs at 90 to 95 percent of maximum effort over distances of 60 to 150 metres with full recovery between repetitions, which trains the body to sustain high mechanical output longer into a race.

The finish itself requires two specific techniques that many sprinters neglect. The first is relaxation: athletes who tighten up in the closing metres, particularly in the jaw, neck, and shoulders, produce a cascade of tension that reduces stride length and frequency. The instruction to relax the face, often used by coaches and visually demonstrated by sprinters who run with an open mouth and loose facial muscles, directly reduces upper body tension and frees up the arm drive. The second technique is the dip finish, where the torso and head are thrust forward over the line at the moment of crossing to advance the chest past the timing beam as early as possible. The dip should be committed and timed so it occurs as the chest crosses the line rather than a full stride before it, which would slow the final steps.
