Section 1: Introduction

1.1 Overview and Governing Body

Short track speed skating became a full Olympic medal sport at the 1992 Albertville Games, having appeared as a demonstration event in 1988 Calgary. The sport is governed by the International Skating Union (ISU) under the ISU Sports Rules – Short Track, the current edition of which took effect 12 June 2026 following adoption of 24 Special Regulations Proposals at the 60th Ordinary ISU Congress in Tenerife, Spain (June 2026). Unlike long track speed skating (which uses time trials on a 400 m oval), short track features pack-style racing on a compact 111.12 m oval marked on a standard ice hockey rink, as set out in Rule 280. The format emphasises tactical racing, split-second decision-making, and physical courage in close-quarters competition.

1.2 Olympic Events

Per Rule 284, paragraph 2, the Olympic Winter Games program consists of Individual Races, Relay Races, and Mixed Team Relay Races:

• Individual (Men & Women): 500 m, 1000 m, 1500 m
• Relay (Men): 5000 m Relay (Rule 284, paragraph 2.c)
• Relay (Women): 3000 m Relay (Rule 284, paragraph 2.c)
• Mixed Team Relay: 2000 m Relay (Rule 284, paragraph 2.c)

1.3 Dominant Nations and Culture

South Korea, China, Canada, the Netherlands, and Hungary have traditionally dominated Olympic short track competition. The sport's intensity, frequent contact, and dramatic photo finishes have made it one of the most-watched events at the Winter Olympics. Controversial penalty decisions and disqualifications are common discussion points, as the margin between legal and illegal contact can be measured in centimetres.

Section 2: Equipment

2.1 Skates

Rule 288, paragraph 1.f) requires that all speed skates have the tubes closed and the blade ends rounded off, with a minimum radius of 10 mm. Blades must be fixed to the boot at a minimum of two points with no moveable parts — this is the provision that excludes hinged "clap skate" mechanisms from short track, since a moving hinge would be hazardous in pack racing with frequent contact.

2.2 Helmet

Rule 288, paragraph 1.a) requires a safety-type helmet that complies with the current ASTM (American Society for Testing and Materials) standard, or another standard approved by the ISU for Short Track. Helmets must have a regular shape and may not have protrusions. Under Rule 288, paragraph 9.a), each Skater is assigned a helmet number before the start of the season which must be displayed on both the left and right side of the helmet and kept for the season.

2.3 Protective Equipment

Rule 288, paragraph 1 lists the equipment every Skater must wear in ISU Events, the Olympic Winter Games, and Winter Youth Olympic Games, and should wear in International Competitions:

• Cut-resistant gloves or mitts (Rule 288, paragraph 1.b): For ISU Events, Olympic Winter Games and Winter Youth Olympic Games, gloves or mitts must be predominantly white.
• Shin protection (Rule 288, paragraph 1.c).
• Long-sleeved and long-legged clothing (Rule 288, paragraph 1.d), per specification in the current ISU Communication.
• Padded or padded hard-shell knee protection (Rule 288, paragraph 1.e).
• Cut-resistant neck protection, fully covering the neck (Rule 288, paragraph 1.g).
• Eye wear protection (Rule 288, paragraph 1.h): For all ISU Events, Olympic Winter Games and Winter Youth Olympic Games, Skaters must wear eye wear protection meeting the approved standards listed in the latest relevant ISU Communication.

Under Rule 288, paragraph 4, the Heat Box Steward determines in the heat box whether a Skater's equipment meets these safety conditions; Skaters whose equipment does not comply are excluded from the race and recorded as Did Not Start.

2.4 Uniform Requirements

Rule 288, paragraph 8.a) requires that during ISU Events and the Olympic Winter Games, all Skaters on the same national Team (Individual and Relay) wear identical uniforms. The name of the country or its official abbreviation must appear on the external part of both lower legs, with characters no smaller than 7 cm high.

Section 3: Playing Area

3.1 Track Dimensions

Rule 280, paragraph 1 sets the standard track: for ISU Events, the Olympic Winter Games and Winter Youth Olympic Games, the track is an oval of 111.12 m laid out in a covered, enclosed and heated ice rink of minimum measurements 60 x 30 m. The width of the straight must not be less than 7 m, and the distance from the apex block of the bends to the barrier must not be less than 4 m. Curves and turns must be made symmetrically. In Semi-Finals and Finals of 500 m, the outside tracks (tracks 1 and 5 when five tracks are used, or 1 and 7 when seven tracks are used) are not skated — only the middle tracks are used (Rule 280, paragraph 1.f).

3.2 Track Markers

Rule 280, paragraph 4 requires track marking blocks of an approved design by the ISU Short Track Technical Committee, with seven blocks used in each curve. Starting lines and the finish line are denoted by lines not more than 2 cm wide, drawn from the barrier; the finish line has a length equal to the width of the straight plus 1.5 m (Rule 280, paragraph 2).

3.3 Safety Infrastructure

Rule 280, paragraph 5 defines three categories of rink padding system: a Basic/Traditional rink board Padding System, where pads are placed against the boarding surrounding the ice; a Hybrid Padding System, where the boarding is partially removed near the curve exits and the start/finish line and self-standing mats are connected together to absorb impact; and a Moveable Padding System, with no boarding around the ice and fully self-standing, interconnected mats. For the Olympic Winter Games, a Moveable Padding system is mandatory. For ISU Events and Winter Youth Olympic Games a Moveable or Hybrid Padding system must be used as a minimum; International Senior and Junior (age categories A & B) Competitions require at least a Traditional system, and International Junior Competitions age categories C & D require at least a Basic Padding System (Rule 280, paragraph 5.e–h).

Section 4: Players & Officials

4.1 Heat Composition

Under Rule 291, paragraph 8.e), the number of Skaters per race at ISU Events, the Olympic Winter Games and the Winter Youth Olympic Games is fixed by a published table:

• 500 m: 5 Skaters in Quarter-Finals, Semi-Finals, and the Final.
• 1000 m: 5 Skaters in Quarter-Finals, Semi-Finals, and the Final.
• 1500 m: 7 Skaters in the Semi-Finals and the Final (1500 m does not run a Quarter-Final field at this size).

Different numbers of Skaters per race may be used for International Competitions held under Rule 283, or when the Quarter-Finals or Semi-Finals form the first round of the competition (Rule 291, paragraph 8.f).

4.2 Officials

Rule 286 defines the officiating panel. The Referee is the chief executive officer and decides all points of dispute and infringements of the rules that can result in sanctions; the Referee's decisions are final (Rule 286, paragraph 4). Up to four Assistant Referees may be appointed, with at least two assigned to the Video Replay System (Rule 286, paragraph 1.a). The Starter controls the starting procedure and gives the verbal start commands (Rule 286, paragraph 13). The Competition Coordinator is responsible for all administrative matters under Rules 292 and 293, including the make-up of races for each Qualifying Round (Rule 286, paragraph 14). The Heat Box Steward checks Skaters' equipment and readiness in the heat box (Rule 286, paragraph 15). A Photo Finish Judge, Lap Scorer, and Lap Recorder record order of finish and lap counts (Rule 286, paragraphs 16, 19 & 20). A minimum of two Track Stewards work at each end of the track (Rule 286, paragraph 22).

4.3 Advancement and Seeding

At ISU Events, the Olympic Winter Games and the Winter Youth Olympic Games, progression on each distance from the first round to the Finals is by elimination (Rule 291, paragraph 4). Race winners qualify to move forward, and additional finish places qualify according to the published Qualification table for the distance (Rule 291, paragraph 8.g). Skaters who were impeded, or who received a Yellow or Red Card, while in a qualifying position at the moment of the infringement are advanced to the next round by the Referee; in Semi-Finals, Skaters in a qualifying position for Final B are advanced there instead (Rule 291, paragraph 8.g). If the scheduled number of Skaters in the next round is not filled by direct qualifiers and advanced Skaters, the fastest remaining Skaters in the next finishing positions may be added (Rule 291, paragraph 8.g). Seeding for the first Qualifying Round of each distance at ISU Events uses the current World Ranking List (Rule 293, paragraph 3.b).

Section 5: Rules of Play

5.1 Individual Distances

• 500 m (4.5 laps): The pure sprint. Explosive starts and early positioning are critical, since overtaking on the compact track is difficult once positions are established.
• 1000 m (9 laps): Combines sprint speed with pack-racing tactics.
• 1500 m (13.5 laps): The most tactical individual event, run in Semi-Finals and Finals fields of 7 Skaters per Rule 291, paragraph 8.e.

5.2 Start Procedure

Rule 294 sets out the start procedure. For ISU Events, the Olympic Winter Games, Winter Youth Olympic Games, and other International Competitions using the "0 False Start" procedure, there is no tolerance built in: once the Starter blows the whistle, any Skater who is late to the line, moves before the gun, slides on or over the line, or otherwise commits a False Start is immediately given a Penalty and excluded from that race — there is no warning-then-restart cycle for the offending Skater (Rule 294, paragraphs 4–11). It is a False Start when a Skater places one or both skates on or over the start line, places one or both hands on the ice, does not have both skates in full contact with the ice, takes the starting position before the command "Ready", or takes it too slowly after "Ready" (Rule 294, paragraph 8.c).

Rule 294, paragraphs 14–22 permit International Competitions (not ISU Events) to instead adopt an optional procedure in which one False Start per race is allowed without penalty, provided this is specified in the Announcement of the Competition. Under that optional procedure, a Skater's first False Start for "delaying the start" draws only a warning; if the same Skater is warned a second time, that Skater receives a Penalty and is excluded from the race (Rule 294, paragraph 19). Once any Skater has caused the race's one permitted False Start, the Starter announces "This race has one False Start," and any further False Start by any Skater in the next start results in a Penalty and exclusion (Rule 294, paragraph 20).

5.3 Overtaking and Passing

Rule 295, paragraph 1.b) permits overtaking at all times, but until Skaters or Relay Teams are beside each other, responsibility for any obstruction or collision falls on the Skater or Relay Team doing the overtaking, provided the Skater or Relay Team being overtaken does not act improperly. Any Skater or Relay Team about to be lapped must move to the outside and may not interfere with the Skater(s) or Relay Team(s) overtaking; interference results in a Yellow or Red Card (Rule 295, paragraph 1.c).

Under Rule 295, paragraph 2, the general racing rule is that Skaters must, by their way of skating, contribute to the honest, sporting and safe progress of the race. Actions considered breaches of the Racing Rules, sanctionable when the facts are clear and obvious with no shared responsibility to establish, are: Off-Track, Impeding, Assistance, Kicking-Out, and Embellishment. Full descriptions of each are set out in the ISU Communication "Guidance to the Racing Rules" and any subsequent update to it (Rule 295, paragraph 2.b).

5.4 Relay Events

Rule 295, paragraph 3.a) caps Relay Team size at 5 Competitors for the World Championships, Junior World Championships and European Championships (World Tour and Junior World Cup limits are set in the relevant Communication). A Relay entry needs a minimum of 4 Skaters to compete; entries with fewer than four are not accepted (Rule 295, paragraph 3.c). Relaying is by touch — a Skater is not in the race until touched by, or having touched, the teammate being relieved (Rule 295, paragraph 3.f). A Skater may be relayed at any time except during the last two laps, which must be skated by one Skater; that final exchange must be completed on the straight before the first block of the corner, and a warning shot signals the start of the last three laps (Rule 295, paragraph 3.g).

Mixed Team Relay (Rule 295, paragraphs 3.m–q) consists of a minimum of two and maximum of four named Women and a minimum of two and maximum of four named Men, of whom any two Women and any two Men race in a given race. The distance is 2000 m (18 laps), relayed on a fixed schedule: four segments of 2.5 laps, then four segments of 2 laps, always in the order Woman–Woman–Man–Man, with the racing order within each gender left to the Team.

5.5 Finishing

Rule 295, paragraph 1.d) provides that a Skater or Relay Team has completed the distance when the Skater has reached the finish line with the leading tip of the skate blade.

Section 6: Scoring

6.1 Placement-Based Advancement

Rule 297, paragraph 1 orders the Skaters/Relay Teams at the end of each race: first all who finished the race, in order of finishing; then those who Did Not Finish (DNF); then those who received a Penalty (PEN); then those who Did Not Start (DNS). Advancement through rounds is governed by this finishing order together with the Qualification tables described in Rule 291, paragraph 8.

6.2 Final and Final B

Rule 291, paragraph 8.d) confirms that at ISU Events, the round of Finals always includes two races: the Final, which determines the winner of the distance, and the Final B, which determines the further ranks. Where only one Skater or Relay Team qualifies for a Final B, that race is not skated and the qualified Skater/Team is assigned the corresponding rank and points (Rule 291, paragraph 8.j).

6.3 Relay Scoring

Relay results follow the same Rule 297, paragraph 1 ordering (finish order, then DNF, then PEN, then DNS) applied to Teams. A Skater/Relay Team that received a Red Card in a Relay is not ranked in the final Relay classification for that race, though results of other Relay events in the Competition are unaffected (Rule 296, paragraph 1.i).

6.4 Tiebreaking

Rule 297, paragraph 2.j) provides that in the case of equal times over a distance, or where no time is available, a draw is used to establish the order between the Skaters/Relay Teams involved.

Section 7: Violations & Penalties

7.1 Racing Infringements

Rule 295, paragraph 2.b) names five sanctionable infringement categories — Off-Track, Impeding, Assistance, Kicking-Out, and Embellishment — applied when the facts are clear and obvious and no shared responsibility needs to be established. Detailed descriptions of each category are published in the ISU Communication "Guidance to the Racing Rules." Where a contact or situation is created by the simultaneous actions of two or more Skaters and has only a minor, non-result-affecting impact, the Referee may instead find Shared Responsibility, resulting in no penalty to any Skater or Team (Rule 296, paragraph 1.c).

7.2 Relay Infringements

Rule 295, paragraph 4.b) defines Relay-specific breaches: Relaying Non-Touch (a relay exchange completed without a touch), Relaying During the Last Two Laps (the final exchange not clearly completed on the straight before the first block of the final two laps), and, in Mixed Team Relay, failure to follow the fixed exchange schedule described in Section 5.4.

7.3 Sanctions (Rule 296)

Rule 296, paragraph 1.b) defines three tiers of sanction. A Penalty applies to an infringement of the Racing Rules. A Yellow Card applies to an unsafe, unsportsmanlike, harmful or hazardous offence, or to more than one Penalty-triggering infringement of Impeding and/or Kicking-Out committed independently of each other in the same race. A Red Card is imposed for an infringement deemed dangerous or grossly negligent, when a Skater is shown two Yellow Cards in the same Event, or for a violation of the ISU Code of Ethics occurring between the Skater's appearance at the Heat Box In and leaving the Heat Box Out after a race.

A Skater or Relay Team given a Penalty or a Yellow Card is disqualified from the race in which the infringement occurred and excluded from the next round of that distance/competition (Rule 296, paragraph 1.d & f). A Skater given a Red Card is not allowed to participate in any further race of the Event, in either Individual or Relay competition, and loses all results on the distance concerned, though results of other individual distances already concluded with a Final are unaffected (Rule 296, paragraph 1.h). If a Skater accumulates two Red Cards within 12 months, that Skater is automatically suspended from all ISU Events, the Olympic Winter Games, the Winter Youth Olympic Games, and International Competitions for at least two months or three applicable Competitions, whichever is longer (Rule 296, paragraph 1.m).

In the ISU Short Track World Tour, a Cumulative Penalty System applies (Rule 296, paragraph 1.e): a Skater who accumulates 3 sanctions (Penalty for Impeding or Kicking-Out, Yellow Card, or Red Card) in the Series cannot be entered in their highest-ranked distance at the next Event of the Series; at 5 sanctions, the Skater cannot be entered in their two highest-ranked distances; from the 7th sanction onward, the Skater cannot be entered in any individual distance at the next Event. Relay infringements do not count toward this total. The list of accumulated sanctions is published in the Protocol after each Event and resets to zero at the end of the Series.

Referee decisions on whether an infringement of the Racing Rules or the ISU Code of Ethics occurred, or that no infringement occurred, are final; no protests against such decisions are allowed (Rule 296, paragraph 1.n).

7.4 False Start Sanctions

Under the "0 False Start" procedure that applies by default at ISU Events, the Olympic Winter Games, and the Winter Youth Olympic Games, any False Start draws an immediate Penalty and exclusion from that race — there is no first-offense grace period (Rule 294, paragraphs 5 & 9–11). Only International Competitions that specifically announce the optional one-free-False-Start procedure retain a warning-then-penalty sequence, in which a Skater's second personal warning for "delaying the start," or any False Start once the race has already used its one permitted False Start, results in a Penalty and exclusion (Rule 294, paragraphs 14, 19 & 20).

Section 8: Safety Considerations

8.1 Crash Protection

Rule 280, paragraph 5 requires protective mats around the entire ice surface at every level of competition, with the required system tier — Basic/Traditional, Hybrid, or Moveable — scaled to the level of competition as described in Section 3.3. A Moveable Padding system is mandatory for the Olympic Winter Games (Rule 280, paragraph 5.e), and a feasibility plan with technical descriptions of the mats' material properties and construction must be submitted with the initial application for ISU Events, the Olympic Winter Games and the Winter Youth Olympic Games (Rule 280, paragraph 5.d).

8.2 Cut Protection

Rule 288, paragraph 1 mandates cut-resistant gloves or mitts, cut-resistant neck protection fully covering the neck, and shin protection for every Skater, addressing the primary serious-injury risk in short track: blade lacerations from other Skaters' blades during falls and collisions. Rule 288, paragraph 5 provides that a Skater who removes required safety equipment before the end of a race receives a penalty, though loss of compulsory or recommended equipment beyond the Skater's control — for example, due to a fall — does not result in a penalty.

8.3 Medical Protocols

Rule 286, paragraph 3 requires that a Medical Doctor and First Aid attendants be in attendance at every Competition. Under Rule 294, paragraph 12, if a Skater is interfered with before the last block of the first curve after the starting line, the Skaters are called back to start again, at the Referee's discretion; more broadly, Rule 296, paragraph 1.o) gives the Referee authority to stop a race and order a re-start or re-run if any irregularity affecting the result occurs.

8.4 Heat Size Limits

The maximum number of Skaters per race is fixed by the table in Rule 291, paragraph 8.e): 5 Skaters for 500 m and 1000 m races through the Final, and 7 Skaters for the 1500 m Semi-Finals and Final. These limits manage collision risk on the compact 111.12 m track, where larger packs increase the probability of chain-reaction contact, particularly in the corners.
