Introduction

I. Understanding Ski Control in Slalom

Slalom is a sport where victories are decided by hundredths of a second. On a racecourse, a skier executes dozens of turns, and in each turn, they can either gain or lose time. The winners are those who can maximize ski control, utilizing their full potential without unnecessary braking.

What Does It Mean to Control Skis Effectively?

Most competitive skiers know how to initiate turns, maintain a trajectory, and complete a course without major mistakes. However, not all of them do it fast. It is a misconception to believe that simply controlling the skis leads to high speed. In reality, inefficient control often slows a skier down rather than helping them accelerate.

To truly generate speed in slalom, a skier must be able to:

• Minimize braking during the ski loading phase.

• Manage pressure and balance throughout each part of the turn.

• Execute transitions between turns efficiently, avoiding energy losses.

• Adapt technique to different conditions – whether skiing on hard or soft snow, steep or flat sections of the course.

Why Traditional Approaches Don’t Always Work

Classic training methodologies often focus on aesthetically pleasing technique but don’t always explain how it directly impacts speed. Many skiers train by mimicking fundamental body positions and movements but later realize that this alone is not enough for consistent race performance.

In slalom, top athletes do not just follow rigid technical models – they adapt their skiing dynamically based on the course and snow conditions. They understand where to apply pressure on the skis, where to release it, how to minimize skidding, and which movements actually save time.

CODE SL: A Systematic Approach to Ski Control

This book is based on the CODE SL system, which analyzes the mechanisms behind effective ski control in slalom. Rather than simply describing "how to do it," CODE SL focuses on:

• The physics and biomechanics of turns – understanding the forces acting on a skier and how to use them effectively.

• Types of transitions and loading methods – when and how to apply pressure to skis for faster turns.

• Proven strategies of top athletes – technical solutions that work in competitive racing.

What Will You Learn from This Book?

• Why conventional training methods don’t always lead to victory.

• How to master ski loading timing.

• How elite skiers navigate a course while minimizing speed losses.

• How to adapt technique to specific conditions.

• How to control skis with maximum efficiency.

This book is not just a theoretical guide – it’s a practical manual for high-speed slalom, designed to help you understand your mistakes, find optimal solutions, and shave time off every turn.

II. What Determines Speed in Slalom?

It’s a common misconception that speed in slalom is determined solely by physical fitness or ski quality. The key factor is how an athlete manages the forces acting on the skis during a turn.

Every slalom skier faces three fundamental challenges:

• Maximizing speed – maintaining momentum through every turn.

• Controlling trajectory – avoiding skids or technical errors.

• Optimizing force distribution – minimizing braking and applying pressure efficiently.

Traditional training methods often focus on perfecting technical form but don’t always explain the mechanics that allow World Cup leaders to ski faster than the rest.

Why Traditional Views on Technique Are Outdated?

Most classic slalom textbooks present a rigid turn model:

1. Unweighting before edge change

2. Early loading of the outside ski

3. Progressive increase in pressure

4. Edge engagement and turn completion

While this model is useful for teaching fundamentals, it doesn’t fully explain the real movements of top-level slalom skiers.

Key Observations:

• Many World Cup leaders apply ski pressure later in the turn yet still maintain high speed.

• Different athletes use different loading and unweighting techniques, adjusting to terrain and conditions.

• There is no single «correct» way to manage skis, but there are universal principles that make technique effective.

The Core Concept: Managing Forces, Not Copying Movements

Two key elements define speed in slalom:

1. Snow Force Vector

When a skier turns, the snow exerts two main forces on the skis:

• Braking force – resists the skier’s movement and slows them down.

• Guiding force – helps direct the skis into the turn and along the arc.

The greater the braking force, the slower the skier. The stronger the guiding force, the more efficiently they carve through the turn.

2. Timing of Ski Loading

The moment when an athlete begins to actively apply pressure to the skis is critical:

• Early loading (before the fall line) – provides stability but can cause excessive braking.

• Mid-turn loading (at the fall line) – allows for better utilization of snow forces.

• Late loading (after the fall line) – if executed correctly, helps preserve speed.

These two factors – not simply body position – determine the efficiency of technique.

How Do Modern Slalom Skiers Apply These Principles?

At the highest level, slalom technique varies significantly among athletes. Despite stylistic differences, top racers share key principles that help them minimize braking and control their skis efficiently.

Different Champions, Different Techniques

Men’s World Cup Leaders:

• Henrik Kristoffersen – often uses late loading, creating pressure through extension, allowing him to shorten the turn radius and accelerate out of turns.

• Loïc Meillard – demonstrates stable, balanced technique with mid-turn loading, ensuring smooth transitions and precise trajectory control.

• Clément Noël – works with both early loading to shape turns in advance and late loading to gain speed out of the turn.

• Manuel Feller – combines aggressive late loading with dynamic body movement, generating powerful pressure phases that allow him to change direction quickly.

Women’s World Cup Leaders:

• Mikaela Shiffrin – a highly versatile technique, emphasizing early loading and stable ski engagement, redistributing pressure effectively throughout the turn.

• Petra Vlhová – a more aggressive style, with powerful mid-turn loading, enabling her to attack the gates while compensating for potential errors.

• Lena Dür – uses smooth ski loading with adaptable pressure management, ensuring stability across different conditions.

• Wendy Holdener – prefers late ski loading with flexion, which helps control turn exits on steep sections.

Common Principles Among Champions:

• Mastering Transitions – choosing when to unweight and load skis based on terrain and turn shape.

• Adaptive Ski Loading – adjusting pressure application to different conditions.

• Managing Force Vectors – controlling braking forces and maintaining forward momentum.

How Do Champions Use Variable Ski Loading Strategies?

In my technical analysis, I have identified four distinct ski loading strategies used by World Cup leaders to minimize braking forces. These strategies include variations in loading timing (early, smooth, powerful, or late) combined with different transition types (A and B).

Here is a comparison table illustrating the four primary turn execution methods in slalom:

This table helps categorize the different technical approaches seen in elite slalom racing. World Cup leaders combine these methods depending on course profile, terrain, and snow conditions to achieve maximum speed with minimal losses.

Example:

• Henrik Kristoffersen frequently employs aggressive late loading at the end of the transition (B), using extension to generate pressure, but he can also shift to a more controlled flexion-based pressure approach.

• Marcel Hirscher mastered precise timing and ski control, applying pressure efficiently. His technique featured:

○ Early loading in extension-based turns (B), initiating pressure immediately after transition.

○ Late loading in flexion-based turns (A), allowing for a brief unweighted phase before engaging the skis.

○ Powerful downward unweighting, enabling quick outer ski engagement and deep edge angles.

There Is No Single “Winning” Technique – Only Effective Solutions

Looking at the World Cup’s top racers, we see that their techniques are not uniform:

• Clément Noël uses an upright stance and flexible transitions, sometimes relying on late ski loading.

• Mikaela Shiffrin blends early and mid-turn loading, adapting based on the situation.

• Manuel Feller favors aggressive late loading, making his turns fast but risk-heavy.

None of these skiers follow a single “correct” model, but they all apply biomechanics and force distribution principles to optimize their performance.
