⛷️ Alpine Skiing, explained
Racers ski down a gated mountain course against the clock — fastest time wins across four core disciplines.
What am I watching?
Alpine skiing is a pure time trial down a mountain. One racer at a time leaves the start gate, skis a course marked by gates (pairs of poles, usually with coloured panels), and the clock decides everything — there are no judges and no style points. The four core disciplines sit on a spectrum from raw speed to rapid-fire turning: downhill (fastest, fewest turns), super-G, giant slalom, and slalom (slowest speeds, quickest turns).
While a racer is on course, watch the split times that flash up at intermediate checkpoints: green means they are ahead of the current leader at that point, red means behind. The best skiers carry speed by taking a 'tight line' — turning as close to each gate as they dare — and by staying in an aerodynamic tuck wherever the course allows. In slalom and giant slalom everyone races twice and the two run times are added together, so a big first-run lead can evaporate in seconds.
The other thing to appreciate is risk management. Margins are measured in hundredths of a second, so racers constantly gamble between a faster line and the chance of missing a gate or crashing out. In slalom especially, a large share of the field fails to finish — a 'safe' skier who stays on course can climb many places simply because rivals above them ski out.
How scoring works
There are no points for style — the winner is simply the racer with the lowest time. Timing runs from the moment the racer's legs trip the 'wand' at the start gate to the instant they cross the photocell beam on the finish line, and results are recorded to the hundredth of a second. Ties to the hundredth are shared: both racers get the same rank.
Downhill and super-G are decided over a single run. Slalom and giant slalom are two-run events held on the same day: everyone's first-run and second-run times are added together, and the lowest combined total wins. In World Cup two-run events the fastest 30 from run one qualify for run two and start it in reverse order — the first-run leader goes last, which builds the drama toward the end of the broadcast.
A racer who misses a gate and does not go back around it, or who straddles a pole, is not classified (marked DNF or disqualified). In a combined event, one speed run (downhill or super-G) and one slalom run are added together, rewarding the rare all-rounder.
Across a World Cup season, top-30 finishers in each race also collect ranking points (100 for a win), which decide the overall and discipline season titles — the 'crystal globes'.
- Lowest time wins — no judges, no style marks.
- Times are measured to the hundredth of a second; exact ties share the same rank.
- Downhill and super-G: one run. Slalom and giant slalom: two runs, times added.
- In World Cup two-run races, the top 30 from run one start run two in reverse order.
- Miss a gate without correcting it and you are out of the results.
- Green split = faster than the leader at that checkpoint; red = slower.
- World Cup races award ranking points to the top 30 (100 for a win) toward season 'crystal globe' titles.

The rules
The course and its gates
Every alpine course is defined by gates the racer must pass through in order, set down a marked, prepared piste. A gate in downhill, super-G and giant slalom is a pair of poles joined by a coloured panel; in slalom it is single poles, alternating colours. Courses are set fresh for each race by a course setter, so no two races are identical, and the terrain — rolls, pitches, sidehills, ice — is as much a part of the test as the gates.
Passing a gate correctly
The racer's ski tips and boots must pass on the correct side of the turning pole. Clipping or flattening a pole with the body is fine — slalom skiers deliberately smash poles out of the way — but if the skis pass on the wrong side ('straddling' or skiing past a gate), the racer must climb back and re-pass it or they are out.
Speed courses vs technical courses
Downhill courses are long with widely spaced gates that mostly guide rather than force turns, plus jumps and long gliding sections. Slalom courses cram tight corridors of gates onto a steep, usually injected (hardened) slope, forcing a rhythm change every second or so. Super-G and giant slalom sit in between.
The four disciplines
Alpine skiing splits into speed events (downhill, super-G) and technical events (giant slalom, slalom). Most World Cup racers specialise in one pair; athletes who win across all four are rare and celebrated.
Downhill
The marquee speed event. One run, the longest course, the highest speeds — well over 120 km/h on the fastest sections — and jumps that can carry racers tens of metres. Because the danger is real, downhill is the only discipline with mandatory official training runs on the actual course before race day.
Super-G
A one-run speed event with more, tighter turns than downhill. Crucially, racers never get a practice run — they memorise the course during a slow morning inspection and then race it blind at speed, which puts a premium on line-reading.
Giant slalom
The foundational technical event, from which most racers' technique is built. Two runs through panelled gates with medium-radius arcs; the purest test of carving technique.
Slalom
Two runs through the tightest gate patterns in the sport. Racers cross-block — punching the single poles aside with shin and arm guards — to take the straightest possible line. The DNF rate is the highest of any discipline; finishing both runs cleanly is itself an achievement.
Timing and deciding the winner
The clock starts when the racer's legs push open the start wand and stops at a light beam on the finish line, measured to the hundredth of a second. Intermediate photocells give split times so viewers and coaches can see exactly where time is gained or lost. In one-run events the fastest single time wins; in two-run events the sum of both runs decides the result. Electronic timing is backed up by independent secondary systems in case of failure.
Start order, bibs and the reverse-30
Racers start one at a time at fixed intervals, in an order drawn from world ranking — in technical events the top-ranked skiers draw bibs within the first group, which matters because the course rutts and deteriorates as more racers come down. In World Cup slalom and giant slalom, the top 30 after run one come back for run two in reverse order of their first-run times: 30th goes first, the leader goes last. This 'flip-30' means the racer with the most to lose skis a progressively rougher course, and it regularly turns the final few starters into a live shootout.
Mistakes, DNFs and disqualification
Missing a gate is the cardinal error. A racer who realises it immediately may hike back up and re-pass the gate — legal but usually fatal to their time. One who skis on is recorded DNF or disqualified after gate judges' reports. Other grounds for disqualification include a false start, receiving outside assistance on course, or equipment that fails inspection. A racer obstructed mid-run — by a course worker, a dog, a rival's lost equipment — can be granted a re-run at the jury's discretion.
Inspection and training runs
Before slalom, giant slalom and super-G races, athletes are allowed only to inspect the course: they slide slowly alongside the gates, memorising the rhythm, terrain and line, but must not ski the course at speed. Downhill is the exception — because of the speeds involved, organisers must hold official timed training runs on the full course before the race, and racers must complete at least one to be allowed to start.
Equipment
Equipment is tightly regulated by the FIS, with different specifications per discipline — as a rule, the faster the discipline, the longer the skis and the straighter their sidecut. Racers wear skin-tight aerodynamic speed suits (which must meet air-permeability rules to prevent 'sail' suits), crash helmets, and in technical events shin, arm and chin guards for hitting poles. Back protectors are standard in speed events. Ski preparation matters enormously: technicians hand-tune edges and wax for the day's snow, and a poorly gliding ski can cost more time than any steering error.
Why slalom skis are short and downhill skis long
Short skis with deep sidecut pivot quickly for slalom's rapid rhythm; long, stiffer skis with a large turn radius are stable at downhill speed and glide faster. Minimum ski lengths and turn radii are set by regulation for each discipline, partly to limit injury risk.
Safety
Speed events are genuinely dangerous, and courses are lined with multiple rows of safety netting — tall A-nets on the most exposed corners, lower B-nets elsewhere — plus padding on obstacles and generous run-off zones. Races are stopped (course hold) when a racer crashes, when weather closes in, or when nets need repair. Juries can shorten courses, lower start positions or cancel races for wind, fog or soft snow. Helmets are mandatory in all disciplines.
The season and what's at stake
The FIS World Cup runs across the northern winter, mostly at classic European venues, with the season's results deciding the overall crystal globe (best across all disciplines) and smaller discipline globes. World Championships are held every two years, and the Winter Olympics every four; both are one-off races where a single run can outweigh a whole season's consistency. Certain World Cup downhills — Kitzbühel's Hahnenkamm and Wengen's Lauberhorn above all — carry a prestige of their own comparable to a major.
India at the Games
India has been represented in Olympic alpine skiing, most recently by Arif Khan, who qualified for both slalom and giant slalom at Beijing 2022 — the first Indian to qualify for two events at a single Winter Olympics. Aanchal Thakur won India's first international skiing medal at an FIS-governed race in 2018.

Stats decoded
| Stat | Unit | What it tells you |
|---|---|---|
| Run time | seconds | Time from start wand to finish beam for one run, recorded to the hundredth of a second. The sport's only true currency — every other number exists to explain it. |
| Total time | seconds | Sum of both run times in slalom, giant slalom and combined events. Final rankings in two-run events are decided on total time, so a first-run lead is only a cushion, not a result. |
| Gap to leader | seconds | How far behind the fastest racer someone finished. World Cup podiums are routinely separated by a few hundredths; a gap over two seconds is a blowout. |
| Split delta | seconds | Time difference to the leader at an intermediate checkpoint. Watching where the delta grows tells you which section of the course a racer is winning or losing. |
| Top speed | km/h | Fastest speed recorded on course, mainly quoted in downhill where racers exceed 120 km/h on the fastest tracks. High top speed only helps if the racer carries it through the next turn. |
| World Cup points | points | Season ranking points awarded to the top 30 in each World Cup race, 100 for a win on a sliding scale. They decide the overall and discipline crystal globes and also drive start-order privileges. |
| Race wins | races | Career or season World Cup victories. Career win counts are the sport's headline greatness metric — the all-time lists are led by racers with 80-plus wins. |
| Podiums | races | Top-three finishes. A better consistency measure than wins alone, since hundredths often separate first from third. |
| Crystal globes | titles | Season titles won — overall or per discipline. Globes measure season-long dominance the way a single race win cannot. |
| Finish rate | % | Share of race starts a skier completes without DNF or disqualification. Especially telling in slalom, where attacking styles trade finish rate for speed; the greats keep both high. |
| First-run rank | position | Position after run one of a technical race. Combined with the reverse-order second run, it defines how much pressure a racer skis under in the final. |
| Start bib | number | Start position in the running order. Lower bibs generally mean a smoother course in technical events, which is why bib draw and ranking protection matter to results. |
Quick answers
How does scoring work in alpine skiing?
There is no scoring panel — alpine skiing is decided purely on time. Each racer skis the course alone against the clock, timed to the hundredth of a second from start gate to finish line. Downhill and super-G are one run; slalom and giant slalom are two runs with the times added together. The lowest time (or lowest total) wins, and a racer who misses a gate without correcting it is out of the results.
Why do slalom skiers hit the poles?
The poles are single, spring-loaded and hinged at the base, and the rule only requires the skis and boots to pass on the correct side. So racers take the straightest possible line and punch the pole out of the way with their shin and arm guards — a technique called cross-blocking. Knocking poles down is completely legal and is simply the by-product of skiing the tightest line.
What happens if a skier misses a gate?
Missing a gate means the run doesn't count. The racer's only remedy is to stop, climb back up, and pass the gate correctly — which costs several seconds and usually any chance of a good result. If they ski on without correcting it, gate judges report the miss and the racer is recorded as DNF or disqualified.
What is the difference between slalom and giant slalom?
Both are two-run technical events, but slalom has much tighter, quicker turns through single poles that racers knock aside, while giant slalom uses panelled double-pole gates spaced further apart, producing longer, carved arcs at higher speed. Slalom rewards rapid footwork and rhythm; giant slalom rewards pure carving technique. Racers also use shorter skis in slalom and longer ones in GS.
How fast do downhill skiers go?
On the fastest World Cup downhill tracks racers exceed 120 km/h, with the quickest sections faster still, and jumps can carry them long distances through the air. That is why downhill is the only discipline with mandatory training runs before race day, and why courses are lined with multiple rows of high safety netting.
Why do giant slalom and slalom have two runs?
Two runs on differently set courses reward all-round technical ability rather than one lucky run, and the format creates a built-in finale: in World Cup races the top 30 from run one start run two in reverse order, so the first-run leader goes last with everything on the line. The winner is the racer with the lowest combined time across both runs.
What is a crystal globe in skiing?
The crystal globe is the trophy for winning a season-long FIS World Cup title. The large globe goes to the overall champion — the racer with the most points across all disciplines all season — and smaller globes go to the winners of each discipline standings. Because it rewards months of consistency rather than one race, many racers value the overall globe as highly as an Olympic gold.
Has India competed in Olympic alpine skiing?
Yes. Indian alpine skiers have appeared at several Winter Olympics, most recently Arif Khan, who qualified on merit for both the slalom and giant slalom at Beijing 2022 — the first Indian to qualify for two events at one Winter Games. Earlier, Aanchal Thakur won India's first international skiing medal at an FIS-governed race in 2018.
Why do so many skiers not finish slalom races?
Slalom margins are so small that racers must attack the tightest possible line through gates arriving nearly every second, on an injected, ice-hard surface. The slightest timing error means a straddled pole or a missed gate, and the run is over. It is normal for a large fraction of a World Cup slalom field to DNF, which is why simply finishing two clean runs can move a racer up many places.
