Alpine combined Alpine combined

An event that ranks racers on the combined time of one speed run and one slalom run. It was the only event held when alpine skiing debuted at the 1936 Olympics, and today it survives only at the Olympics and world championships. It favors all-rounders, and a technical specialist overturning a speed skier's lead in the slalom leg is a common storyline. A team version, pairing one speed and one slalom racer per country, has recently been added.

Angulation Angulation

Bending at the hip and knee so the legs lay far over on edge while the upper body stays comparatively upright and stacked over the outside ski. Leaning the whole body inward without this correction collapses the moment grip is lost, so angulation is the necessary counterbalance. The clearest sign of an elite giant slalom racer is shins nearly touching the snow with level shoulders, and this is usually the most visible gap between a World Cup skier and a strong recreational one.

Back seat Back seat

A stance where weight shifts onto the heels and the upper body falls behind the feet. Without pressure on the front of the ski a turn cannot properly start, and in a fall this stance often leads directly into the phantom-foot position that tears the ACL. It is an almost universal habit among self-taught beginners and can take two full seasons to correct. Keeping constant shin pressure on the front of the boot tongue is the standard fix.

Binding Binding

The mechanism that locks a boot to the ski and releases it when a dangerous force is applied. It has a toe piece and a heel piece, each with its own release strength set by a DIN value. Most beginner skis are now sold as a complete system with the binding already mounted. Because it is the only true safety device in a ski setup, buying one used carries real risk, and a binding past a manufacturer's certified service life often cannot be repaired at all for lack of parts.

Carving Carving

A turn in which the ski bends into reverse camber and follows the arc drawn by its own sidecut, leaving a thin, pencil-like track in the snow. A skidding ski acts as a brake, so a carved turn is always faster. Sustained carving only became possible once shaped skis reached the market around 1993, and modern race technique is essentially the pursuit of a fully carved arc under loads several times body weight.

Course inspection Course inspection

The only chance a racer gets to study a course before racing it. Skiers side-slip slowly beside the set line, never skiing it, checking terrain changes, gate spacing, light and snow condition. In super-G, which has no training runs at all, the quality of inspection can matter as much as skiing ability, and racers are commonly seen closing their eyes at the start and mentally tracing the whole sequence.

Course setter Course setter

The single coach, drawn from a competing nation, who personally plants every gate for a run and is accountable for the result. The two runs of a technical event are normally set by coaches from different countries. Setters deliberately vary rhythm, hide gates over rolls, and place traps on the steepest pitches, which is why disputes over a setter favoring their own nation's racers surface periodically in the sport.

Crystal Globe Crystal Globe

The season-long trophy awarded since 1967 to whoever tops the World Cup points table across every discipline in a given winter. Shaped like a glass sphere, it is the sport's most prestigious annual award. An Olympic gold is the result of a single day, while this trophy demands consistency across an entire winter, which is why some racers rate it as an even harder achievement than an Olympic title.

DIN setting DIN setting

The release strength value set on a binding, determining how much force is needed before it lets the boot go in a fall. It is calculated from body weight, height, boot sole length, age and skill level, and a higher number means the binding releases less easily. Set too low, skis pop off during ordinary skiing; set too high, the knee absorbs impact that should have released the boot. A shop calculating this correctly and checking release each season is the single most effective step against a torn ACL.

DNF (Did not finish) DNF (Did not finish)

The result-sheet mark for a racer who fell or left the course before crossing the finish line. It is distinct from a DSQ, given for missing a gate, and from a DNS, given when a racer never starts at all. Unlike most sports, even elite alpine racers post multiple DNFs in a season, because a line safe enough to guarantee a finish is rarely fast enough to win.

Downhill Downhill

The sport's blue-riband event, with up to 800 to 1,100 metres of vertical drop for men and runs lasting from 90 seconds past two minutes. Gates control speed and steer racers into safe lines rather than forcing sharp turns. It is the only discipline with compulsory official training runs, normally held on three separate days before the race, and skis must be at least 218 centimetres long with a minimum 50-metre sidecut radius, which makes them nearly impossible to turn at low speed.

DSQ (Disqualification) DSQ (Disqualification)

A result-sheet mark applied when a racer fails to pass a gate correctly, the sport's most common disqualification. Skis shorter than the required minimum, an undersized sidecut radius, a race suit that fails the required air-permeability test, or a boot sole above the permitted stand height also bring an immediate DSQ. Suits are checked before and after racing, sometimes by cutting a fabric sample for testing.

Edge bevel Edge bevel

The angle ground into a ski's base and side edges during tuning. A larger base bevel bites the snow less and skis more smoothly, while a steeper side bevel grips harder but becomes touchier to ski. Disciplines are tuned differently — slalom skis favor grip with a steep side bevel, downhill skis favor glide with a duller edge — and top teams adjust bevel angles daily to match changing snow conditions.

Edge change Edge change

The moment a racer releases the edges from the previous turn and engages the opposite edges for the next one, arguably the single most important timing decision in ski racing. Fast racers change edges earlier than instinct suggests, engaging the new edge while still traveling across the hill so the ski is already arcing as it approaches the gate. A late edge change forces the turn to finish below the gate, bleeding speed that compounds into every gate that follows.

Fall line Fall line

The steepest path down a slope, the line an object would follow rolling downhill with no resistance. Every technical description in skiing is built around this line, and a turn is defined as a movement across it. A fast line keeps the skis already pointed toward the fall line as they pass a gate. Beginners instinctively lean their body away from it the moment they face it, which is the actual starting point of a backseat stance.

Flip 30 Flip 30

The rule reversing the start order for a technical event's second run: the top 30 finishers from the first run start again in reverse order, so 30th place goes first and the first-run leader goes last onto the most rutted, chewed-up snow. It is why large first-run leads get overturned so often, and it is regarded as the sport's own built-in equalizer. Anyone outside the top 30 simply follows in their original first-run order.

Forerunner Forerunner

A racer who skis the course before the first official bib, testing conditions and gate settings without counting toward the results. Forerunners are typically promising local or host-nation racers, checking that the course, timing equipment and gate placement are all working correctly. It is also one of the few chances a developing young racer gets to actually ski an elite competition course before it opens.

Gate Gate

The marker a racer must pass through, made of two poles. Both ski tips and both feet must cross the imaginary line between the poles for the pass to count. Slalom marks turns with a single pole; giant slalom and the speed disciplines use two poles joined by a cloth panel. Gates alternate red and blue, letting a racer read the rhythm of upcoming turns at a glance.

Gate blocking Gate blocking

Striking a slalom pole with a hand, forearm or shoulder to knock it flat while passing through the gate on the tightest possible line. It became possible once hinged, breakaway poles replaced rigid bamboo in the early 1980s, and it fundamentally shortened slalom lines overnight. Clearing the pole with the inside arm while keeping the outside arm forward is called cross-blocking. It is exactly why slalom racers wear shin guards, forearm guards, pole guards and a chin bar.

Giant slalom Giant slalom

Often rated by coaches as the purest technical test in the sport, run over 300 to 450 metres of vertical drop with 45 to 65 gates, each marked by two panels. Turns are long and heavily loaded, putting several times body weight through the outside ski. Minimum ski length is 193 centimetres for men and 188 for women, with a minimum sidecut radius of 30 metres.

Grooming Grooming

Smoothing and packing a slope's surface with a snowcat, usually done overnight or after night skiing ends at US resorts. A freshly groomed surface shows corduroy-like ridges and offers the most consistent conditions for practicing carved turns. It is also why gate training is typically scheduled for early morning right after grooming, before public traffic chews the surface into ruts.

Inclination Inclination

Leaning the entire body toward the inside of a turn to hold a high edge angle at speed, necessary to counter centrifugal force. Used alone it collapses inward the instant the ski loses grip, which is why it is always paired in practice with angulation. Getting the balance between the two wrong is the most common cause of losing an edge mid-turn.

Masters racing Masters racing

A racing category for adults, typically 21 and older, divided into age brackets. In the United States it runs through U.S. Ski and Snowboard-sanctioned masters series and NASTAR events at member resorts, alongside individual resort club races. Most US masters events lean toward giant slalom, entry fees run roughly $20-60 per race, and the season is short enough that most races cluster into January and February.

Para alpine skiing Para alpine skiing

Alpine ski racing at the Winter Paralympics, covering the same four disciplines as able-bodied racing plus combined and team events. Athletes compete in standing, sitting and vision-impaired categories; in the vision-impaired category a guide skis just ahead, calling the course over a radio link. A factored time system multiplies each racer's raw time by a coefficient tied to their impairment class, so the finish-line time and the final ranked time can differ.

Parallel event Parallel event

A head-to-head format in which two racers start together on two identical, side-by-side courses. Racers typically swap course sides and run twice, with the combined time deciding the winner. The Olympic and world championship mixed team event uses this format, pitting four-person national teams against each other. It is the one alpine format where the crowd sees who is winning in real time, which makes it popular for city-center exhibition events.

Racing line Racing line

The fastest path through a gate sequence, which takes the ski above the pole rather than beside it so the turn finishes before the panel instead of after it. A late line forces the turn to finish below the gate, scrubbing speed and arriving late to the next one, a compounding effect coaches call being behind.

Seed group Seed group

A block of racers grouped by ranking to determine start order. In technical disciplines like slalom, top-seeded racers draw among themselves for the earliest start numbers, giving them the smoothest snow before ruts form. Because a ski course wears down as it is used, start number is a competitive resource nearly as valuable as raw ability, and a lower-seeded racer effectively skis a different, harder course.

Sidecut radius Sidecut radius

The radius of the circle described by a ski's hourglass-shaped edge if extended into a full curve. A smaller radius produces short, quick turns; a larger radius produces long, fast ones. FIS sets minimum radii per discipline — 30 metres for giant slalom, 50 metres or more for downhill. Beginner carving skis typically run 12-16 metres, shaped specifically so the ski arcs on its own once tipped on edge.

Skidding Skidding

A turn in which the ski's tail washes sideways rather than following an arc, leaving a wide, smeared track in the snow. A skidding ski functions as a brake, wasting energy that should be carrying the racer downhill. Beginners struggle to carve not from lack of strength but from twisting the foot before the ski has time to turn on its own; even elite slalom racers blend in controlled skidding where turns are too tight to carve cleanly.

Skier's thumb Skier's thumb

An injury named directly for this sport: falling with a pole still gripped drives the hand into the snow and forces the thumb outward, straining or tearing the ulnar collateral ligament. It is far more common in beginners than experts and severe cases require surgery. Prevention is simple — never thread the wrist through the pole strap — which is why strapless race-style grips exist.

Slalom Slalom

The shortest and most technical discipline, covering 180 to 220 metres of vertical drop with 55 to 75 gates cleared in 50 to 60 seconds, close to one direction change per second. Single poles rather than two-panel gates mark the turns, and racers knock them down with hands, shins and shoulders. Minimum ski length is 165 centimetres for men and 155 for women, and the result combines two runs skied the same day.

Small globe Small globe

The season trophy awarded to the top points scorer in a single discipline, one each for slalom, giant slalom, super-G and downhill. It ranks below the overall Crystal Globe, which requires strong results across every discipline. For a specialist racer, a small globe is often the realistic top goal, since the overall title is reserved for the small number of true all-rounders who can score points in all four.

Snowplough (wedge) Snowplough (wedge)

A stance with the ski tips brought together and tails spread apart, forming a triangle, taught in nearly every beginner lesson as the first tool for controlling speed and stopping. Holding this stance on terrain beyond a beginner's ability catches the inside edge easily and is a common cause of MCL injury, which is why choosing appropriate terrain matters more than the wedge itself. The next stage is bringing both skis parallel.

Straddle Straddle

Passing one ski on each side of a turning pole, resulting in an immediate disqualification. It is the sport's most common DSQ, reviewed by video gate judges on marginal calls. It is why a winning-looking time can still turn into a DSQ on the results board, and why coaches at the finish line check the gate judges' flags before checking the clock.

Streif Streif

The downhill course at Kitzbuhel, Austria, the most feared and famous stage in the sport. Raced every January at the Hahnenkamm meeting, it opens with the Mausefalle, where the pitch exceeds 85 percent and racers fly up to 80 metres through the air. Winning here is treated as an honor comparable to an Olympic gold, and in Austria the race's television ratings sometimes outdraw any football match played that year.

Super-G Super-G

Short for super giant slalom, a discipline bridging giant slalom and downhill, introduced to the World Cup in 1982 and the Olympics in 1988. It is decided by a single run and critically offers no training runs at all, so racers ski the course at full speed on nothing but a memory of their on-foot inspection. That combination makes course-reading ability and nerve especially decisive, and DSQ and DNF rates run high.

Tuck position Tuck position

The aerodynamic stance used above roughly 80 km/h: knees deeply bent, back flat, forearms parallel and forward, head tucked between the arms. Above that speed, air resistance becomes the dominant force acting on a racer, making body shape matter more than anything happening at the ski. Jean Vuarnet's low 'egg' position at the 1960 Olympics popularized it, and it became the standard through the Jean-Claude Killy era that followed.

Vertical drop Vertical drop

The elevation difference between a course's start and finish, the most basic figure separating the four disciplines. FIS specifies roughly 180 to 220 metres for men's slalom, 300 to 450 for giant slalom, 400 to 650 for men's super-G, and 800 to 1,100 for men's downhill. Slalom's gate count is derived from this figure too, set at 30 to 35 percent of the vertical drop in metres.

Water injection Water injection

Preparing a course by injecting or spraying water into the snow and letting it freeze overnight into an ice-hard surface. This ensures the 30th racer down the course faces conditions nearly identical to the first, and virtually every World Cup and championship course receives this treatment. It looks slick to a casual viewer but exists purely for fairness, and giant slalom courses at major US races increasingly use it too.

Waxing Waxing

Melting wax into a ski's base to reduce friction against the snow. The wax type is matched to snow temperature and humidity, and it works together with a structured base pattern to determine glide speed. A well-prepared pair of skis can be worth several tenths of a second over a two-minute downhill, which at a venue like Kitzbuhel is the gap between winning and finishing tenth, and it is why teams guard their wax rooms closely.
