⛷️Tactics

Ski Racing · Two runs, one mountain, hundredths of a second — the only sport where the athlete is the fastest object on the field.

There is no playbook in alpine skiing because there is no opponent to deceive, but there is a great deal of tactics — most of it decided before the start gate opens. A racer inspects a course once, on foot or side-slipping, and must convert what they see into a memorised sequence of intentions: where to open the line, where to take the risk, which gate is the trap, which section will decide the run. Coaches spend the morning arguing about two or three specific turns, because that is usually where the race is lost.

The physics underneath is constant across all four disciplines. Speed is generated by staying in the fall line as long as possible and by minimising the time the ski is turning rather than travelling. Speed is destroyed by skidding, by turning late, and by presenting a larger surface to the air. Everything below — the racing line, the early edge change, angulation, blocking, the tuck — is a technique for buying more of the first and less of the second. The diagrams show how the same problem looks entirely different when the gates are eight metres apart and when they are eighty.

Slalom: 55-75 gates, a turn every second

1 2 3 4 5 6 7 8 9 10 11 12 13 F
A slalom course packs 30 to 35 direction changes into every 100 metres of vertical drop, so a racer changes edges roughly once per second for the length of the run. Turning poles are single, hinged and designed to be knocked flat. The setter builds rhythm and then deliberately breaks it: this course opens with a regular rhythm section, drops into a hairpin where two gates sit almost directly in the fall line, and later includes a delay gate that arrives later than the eye expects and punishes anyone already committed to the next turn. Because the offsets are small, the racing line barely deviates from a narrow corridor down the hill, and the whole contest is about how early the edge change happens and how little the ski slides. Second-run ruts turn the same course into a different problem entirely, which is why the reverse-30 start order overturns so many first-run leads.

Giant slalom: the long, loaded arc

1 2 3 4 5 6 7 8 F
Giant slalom sets direction changes at 11 to 15 percent of vertical drop, roughly a third as many turns as slalom over a longer course, with gates marked by paired panels and offsets wide enough that the racer must genuinely travel across the hill. Speeds reach 60 to 80 km/h and the outside ski carries several times body weight through the belly of the turn, which is why FIS mandates 193-centimetre skis with a minimum 30-metre radius. Tactically this is the discipline of the clean arc: any skid bleeds speed that cannot be recovered before the next gate, and a turn started late forces a sharper, slower correction below the panel. Course-setters use terrain rather than geometry to attack, hiding a gate over a roll or setting a tight turn at the entry to a steep pitch so that anyone carrying too much speed is thrown wide.

Super-G and downhill: gates as speed control

1 2 3 4 5 6 F
In the speed disciplines the gates stop being turns and start being instructions. Super-G requires only about 35 direction changes for men, spaced at least 25 metres apart; downhill gates must be at least eight metres wide and exist mainly to slow racers before danger, steer them away from hazards and force a specific approach to a jump. Between them the racer is simply travelling, at 100 to 140 km/h, choosing a line across natural terrain. The tactical currency here is glide: staying low in the tuck, absorbing compressions so the skis stay on the snow, and pre-jumping crests so the body does not fly further than necessary — every metre of air is a metre without acceleration. Super-G is the harder mental test, because there are no training runs at all: the racer inspects on foot, memorises the sequence, and gets one attempt.

The racing line through a gate sequence

G1 G2 G3 G4 G5 G6
The single most important idea in ski racing is that the fastest line is not the shortest one. A racer who aims straight at the panel arrives at the gate still turning, has to finish the arc below it, and is then late and slow into the next one — the classic death spiral of an amateur run. The correct line takes the ski high and early, so that the apex of the turn falls above the gate rather than beside it, the ski is already pointing down the hill as it passes the panel, and the racer exits with the fall line rather than across it. That costs a fraction of distance and buys acceleration through every subsequent turn. In this sequence the line rounds out well above gates 2 and 4, tightens deliberately at gate 3 where terrain steepens, and straightens through gates 5 and 6 to carry maximum speed into the finish schuss.

Key concepts

Carving versus skidding

A carved turn is one in which the ski bends into reverse camber and travels along its own arc, leaving a thin pencil line in the snow; a skidded turn is one in which the tail washes sideways, leaving a smear. Carving is faster because a skidding ski is a brake — energy that should be carrying the racer down the hill is being spent scraping snow sideways. The shaped skis introduced from 1993 made sustained carving possible for the first time, and modern racing technique is essentially the pursuit of a fully carved arc under loads several times body weight. In slalom, where turns are too tight and too fast to be carved cleanly throughout, elite racers carve as much of each turn as terrain and rhythm allow and accept a controlled pivot where they cannot.

Angulation and inclination

To hold a high edge angle at speed, a racer must lean the body toward the inside of the turn — inclination — but pure inclination collapses inward as soon as the ski loses grip. Angulation is the correction: the skier creates angles at the hip and knee so the upper body stays comparatively upright and stacked over the outside ski while the legs are laid far over. The visible signature of elite giant slalom is a racer whose shins are nearly touching the snow while the shoulders remain level and the outside leg is straight and loaded. Getting the balance wrong is the most common cause of losing an edge mid-arc, and it is where the difference between a World Cup racer and a strong club skier is most obvious in slow-motion video.

The racing line and the early edge change

The fastest line takes the skier above the gate and gets the turn finished before the panel rather than after it. Practically, this means the edge change happens earlier than instinct suggests — the racer releases the old turn and engages the new edges while still travelling across the hill, so the ski is already arcing as it approaches the gate and pointing down the fall line as it passes. A late edge change forces the racer to complete the turn below the gate, scrubbing speed and arriving late at the next one, which compounds across a course. Coaches call the resulting cascade being behind, and it is why a run can visibly fall apart three gates after the actual mistake.

Blocking and cross-blocking

Since hinged breakaway poles replaced rigid bamboo in the early 1980s, slalom racers no longer ski around the gate — they ski through it. Blocking means striking the pole with the outside arm or hand as the body passes, keeping the line tight; cross-blocking means clearing the pole with the inside arm or shoulder while the outside arm stays forward, permitting an even tighter line. Racers wear shin guards, forearm guards, pole guards and chin bars precisely because the pole is going to be hit dozens of times per run at 40 km/h. The technique fundamentally changed slalom lines and is why footage from the 1970s looks so much wider than a modern run down the same slope.

The tuck and aerodynamics

Above roughly 80 km/h, air resistance becomes the dominant force acting against a racer, and the position of the body matters more than anything happening at the ski. The tuck — knees deeply bent, back flat and horizontal, forearms parallel and hands forward, head tucked between the arms — was popularised by Jean-Claude Killy's era after Jean Vuarnet used a low egg position to win Olympic downhill in 1960. Modern racers are tested in wind tunnels and drilled to hold the tuck through compressions where the load makes it physically punishing. Suits are regulated to a minimum air permeability of 30 litres per square metre per second precisely to prevent teams engineering their way past the rules.

Gliding, tune and structure

In downhill and super-G a substantial share of the result is decided before the racer leaves the start hut. Service technicians grind a base structure appropriate to the snow temperature and humidity, select a wax and a running surface, and set the edge bevel — the angle between base and side edge — to trade grip against glide. Gliding sections separate the field even when every racer is skiing the same line: a well-prepared pair of skis can be worth several tenths over a two-minute downhill, which at Kitzbuhel is the difference between winning and finishing tenth. Teams guard their wax rooms accordingly, and a top downhiller's relationship with their technician is one of the closest working partnerships in the sport.

Terrain absorption and pre-jumping

Airtime is lost time: a racer in flight is neither accelerating nor steering, and lands with a compression that costs more speed still. The craft of speed skiing is therefore to stay on the snow. Racers absorb compressions by retracting the legs as the terrain rises and extending as it falls, keeping the centre of mass on a smooth path while the skis follow the ground. Over a crest they pre-jump, taking off deliberately before the lip so the flight is flatter and shorter than the terrain would otherwise impose. The Streif at Kitzbuhel is the ultimate examination of this skill, with the Mausefalle producing jumps of up to 80 metres for racers who fail to manage it correctly.

Inspection and visualisation

Racers are never permitted to ski a course before racing it. Inspection means side-slipping slowly beside the line with a coach, noting terrain changes, gate offsets, light and snow conditions, and identifying the two or three passages that will decide the race. What follows is memory work: at the start, racers can be seen with eyes closed, hands tracing the sequence, running the entire course mentally in something close to real time. In super-G, where there are no training runs, the quality of inspection is arguably worth more than the quality of skiing. In downhill, three official training descents let racers test the line, but the race is still skied fundamentally from memory.

Bib number, ruts and reading the snow

A ski course is a consumable surface. In slalom, ruts form in the turning areas within a dozen runs, changing the effective line and offering later starters either a track to follow or a trap that throws them out of balance. In speed events, snow softens with sun and traffic, and light flattens as cloud moves in. This is why start-order rules matter so much: the leading racers draw among themselves for the earliest bibs, and why the flip-30 rule for second runs — leader last on the roughest snow — is the sport's built-in equaliser. Reading what the course has become since inspection, and adjusting line mid-run, is a distinct and underrated skill.

How it evolved

Alpine technique has always been downstream of equipment. Hannes Schneider's Arlberg method was built for long, soft, wooden skis with leather bindings, and taught skiers to rotate the whole body to get the ski around. Metal and fibreglass construction in the 1960s stiffened the platform enough for the modern independent-leg action to emerge; rigid boots moved the control point from the ankle to the shin; and the introduction of hinged slalom poles in the early 1980s let racers abandon the wide arc around the gate for the straight line through it. Each change looked incremental and each one made the previous generation's technique instantly obsolete.

The deep sidecut of the shaped ski, launched in 1993, was the largest single rupture. Turning stopped being something a racer did to the ski and became something the ski did once tipped on edge, which shifted the entire technical emphasis to edge angle, early pressure and hip angulation, and pushed forces and speeds sharply upward. The regulatory response has driven the last two decades: minimum lengths and radii per discipline, boot stand heights, suit permeability limits and compulsory back protection, all revised repeatedly as teams find the edges. The next frontier is protective rather than performance-led — airbag vests are already in wide use in speed events, and the argument now is not whether racers should wear them but whether FIS should make them mandatory.
