Speed Skating (ISU) — Official Rules

Speed skating is a racing sport in which competitors skate on ice over set distances on long steel blades, racing counter-clockwise around an oval and finishing when the leading tip of the skate blade reaches the finishing line after the prescribed number of laps. There is no goal-scoring: in individual-time races the lowest time wins, and in pack/heat races the first skaters across the line advance or win. The sport has two distinct ISU disciplines - Long Track (raced in pairs against the clock on a 400m oval) and Short Track (raced as a pack of 4-8 skaters on a tight 111.12m oval). A competitor must cover the whole distance on skates and follow the marked track.

Speed skating is governed worldwide by the International Skating Union (ISU), founded in 1892, which also governs figure skating. The applicable rules are the ISU Special Regulations & Technical Rules - Speed Skating and the parallel Special Regulations & Technical Rules - Short Track Speed Skating, in their 2024 edition (published 6 September 2024). That edition was in force for the 2025/26 season and the 2026 Olympic Winter Games (Milano Cortina). With effect from 12 June 2026 the ISU consolidated and re-issued these as the ISU Speed Skating Sports Rules (2026); the core technical content (tracks, distances, scoring) is unchanged. They govern the World Single Distances Championships, World Allround / Sprint Championships, World Cups and the Olympic Winter Games.

The two ISU speed-skating disciplines differ fundamentally:

• Long Track: skaters race two at a time (in pairs) against the clock on a 400m oval with two separate competition lanes, changing lanes once per lap on the crossing straight; the result is decided by time. Mass Start and team events are exceptions raced as a pack.
• Short Track: 4 to 8 skaters race together as a pack on a 111.12m oval inside a 60 x 30m rink; there are no lanes, contact and tactics are part of the race, and the result is decided by finishing position through qualifying rounds, semi-finals and finals. The disciplines have separate rulebooks, officials and skate equipment, and are contested as distinct programs at the Olympic Winter Games.

A Standard Speed Skating Track has a competition track of two lanes, maximum 400m and minimum 333 1/3m long, with two curved ends each of 180 degrees whose inner-curve radius is between 25m and 26m. The inner competition lane is 4m wide and the outer lane at least 4m wide. The crossing area is the whole length of the straight from the end of the curve. ISU Championships, World Cups and the Olympic Winter Games must be run on a 400m track with a warm-up lane of minimum 4m width inside the competition lanes, on artificially frozen ice inside a heated, enclosed building to protect skaters from wind and weather.

On a standard 400m track the inner line of each lane is fully painted and marked by snow or movable blocks placed on the inside of the painted line; these blocks must not be moved by a skate. The starting and finishing lines for all distances are positioned so the finishes line up correctly with the lap count. Non-standard tracks (for events not following the general racing rules, e.g. on lakes) must still have two lanes at least 200m long, inner radius at least 15m, crossing area not less than 40m and lane widths of at least 2m; some such events may be arranged without separate lanes.

World Records and championship programs are recognised over the individual distances 500m, 1000m, 1500m, 3000m, 5000m and 10 000m (the 10 000m for Men, with Women's longest single record distance being 5000m). A typical World Single Distances Championship / Olympic single-distance program is:

• Women: 500m, 1000m, 1500m, 3000m, 5000m and the Mass Start.
• Men: 500m, 1000m, 1500m, 5000m, 10 000m and the Mass Start. The 500m is often skated twice with the result decided by the combined time of two runs, the skater starting once in each lane to equalise the inner/outer-lane advantage.

Historic championship formats combine several distances scored on points (see Chapter 8):

• Allround combination: four distances over two days. The classic Men's set is 500m, 5000m, 1500m, 10 000m; the classic Women's set is 500m, 3000m, 1500m, 5000m.
• Sprint combination: 500m, 1000m, 500m, 1000m (two of each over two days, swapping lanes each day). The overall winner is the skater with the lowest total points across all distances; a skater must complete all distances to be classified for the title, though limited fields may apply to the longest final distance.

In individual distances the two skaters of a pair are identified by armbands on the right arm: white for the inner lane and red for the outer lane (yellow for a middle lane in 3-up sprint heats). On 'Go to the Start' skaters place themselves between the pre-start line and the starting line (2m apart), take a stable position, then on 'Ready' take their final position and hold it absolutely until the shot. Skaters may not touch or cross the starting line; all of the skate must stay behind the line. There must be a distinct interval of about 1 to 1.5 seconds between 'Ready' and the firing of the (powder or electronic) start pistol.

A false start is declared when a skater is intentionally slow taking position, breaks from the mark causing the other to follow, or leaves position after 'Ready' but before the shot. The skaters are recalled by a second shot and/or whistle, with a stop signal (red flag or red light) at 50-60m. The Starter warns the skater who commits the first false start of the pair; a second false start by that pair leads to disqualification of the offending skater. Electronic photocells or cameras may be used to detect and verify false starts, and light pedestals (white for first false start, red for disqualification) may indicate the decision.

Except for Team competitions and Mass Start races, skaters race in pairs, starting in the lane drawn for them and racing counter-clockwise (inner side on the left). A skater must keep entirely within the designated competition lane. If a skater who stays wholly within their lane is interfered with by the other, the offending skater is disqualified. A skater who completely crosses the line into the other lane or the warm-up lane with the full skate may be disqualified even without interfering with anyone; more than one such confirmed offence brings disqualification (subject to the exceptions below).

Each lap the skater in the inner lane must change to the outer lane on the crossing straight (the straight between the end of the curve and the start of the next curve) and vice versa; a breach is a disqualification. Exception: in the first straight of the 1000m and 1500m on a 400m track there is no lane change. When leaving the curve onto the crossing straight, the skater changing inner-to-outer must not hinder the skater changing outer-to-inner (even from another pair in a quartet); the skater leaving the inner lane carries this responsibility. Cutting the inner line of the lane in the curve (so the marker blocks are passed on the inside) is forbidden and brings disqualification.

When a faster skater overtakes another in the same lane (e.g. a lapping situation or a quartet catch-up), both skaters share responsibility to allow a smooth, collision-free pass; the skater in front must hold their relative line and the overtaking skater must avoid the collision. After being overtaken, the overtaken skater must remain at least 10m behind and may not act as a pacemaker - pace-making is forbidden and brings disqualification (it does not apply between team-mates in team events). A skater who leaves the lane due to a fall is not disqualified if returning directly to the designated lane.

The Mass Start is raced as a pack with no separate lanes over 16 laps (6400m on a 400m track). Skaters line up in rows of maximum 6 and may not accelerate during the first lap until a signal is given (breach = disqualification). At ISU/Olympic level there are 3 intermediate sprints (after laps 4, 8 and 12) plus a final sprint. Points are awarded as follows:

• Intermediate sprints: first 3 skaters get 3 - 2 - 1 points.
• Final sprint: first 6 skaters get 60 - 40 - 20 - 10 - 6 - 3 points. The highest total of sprint points wins; ties are broken by the final-sprint order, and the design ensures the top 3 of the final sprint take the top 3 race ranks.

In the Team Pursuit two teams start simultaneously on opposite straights and skate on a single competition lane (using the inner-lane/warm-up-lane demarcation). A team has 3 or 4 skaters and its finishing time is that of the third skater to cross the line; if fewer than 3 finish, the team is disqualified. The distance is 8 laps for Men and 6 laps for Women (on a 400m track). In elimination-phase formats, a team is declared the winner the instant its third-placed skater overtakes the opposing team's third-placed skater. Team-mates may pace-make for each other (unless a skater has been lapped by them).

In the Team Sprint the number of laps equals the number of skaters in the team (typically 3 laps for a 3-skater team); the team's result is its finishing time, with start/finish set as for the Team Pursuit. World Records are also recognised for a Mixed Relay over 6 laps. As in the Team Pursuit, team-mates may assist and push each other, but must not impede other teams, and each skater wears distinct identification (white, red, yellow, blue armbands for skaters 1-4).

A skater completes a distance when the front tip of the blade of the first-arriving skate touches or reaches the finishing line after the prescribed laps. Modern ISU events use automatic timekeeping with photo-finish, recording official times to thousandths of a second; manual timekeeping with stopwatches is the fallback. Lap scorers must visibly display the number of laps still to skate, and a bell is sounded 20-30m before the start of the last lap. Deliberately kicking out a skate or throwing the body across the finishing line is forbidden and brings disqualification.

Multi-distance championships (Allround and Sprint) are decided on the samalog point system, which normalises every distance to a 500m equivalent: the number of seconds for a 500m race counts directly as points, and for longer distances the time is divided proportionally - 1/2 of the seconds for 1000m, 1/3 for 1500m, 1/6 for 3000m, 1/10 for 5000m and 1/20 for 10 000m. Points are calculated to three decimals (the fourth decimal is dropped). The skater with the lowest total points across all distances wins; equal totals share the rank.

Short Track is skated on an oval of 111.12m inside a covered, enclosed, heated ice rink of minimum 60m x 30m (typically a hockey rink). The straight is at least 7m wide, and the distance from the apex block of a bend to the barrier is at least 4m. There are no separate lanes: the inside of the curve is marked by track-marking (apex) blocks, and skaters race the shortest line around the pack. Multiple parallel tracks are laid out (shifted by up to 0.7m for 7 tracks, 1m for 5 tracks) so the apex blocks can be moved between races to preserve the ice, while one common finish line is used.

Individual short track distances are 500m (4.5 laps), 1000m (9 laps) and 1500m (13.5 laps). Relay races are 3000m for Women, 5000m for Men, and the 2000m Mixed Team Relay (18 laps). Skaters race counter-clockwise in a pack of 4-8 through a knockout structure of heats, quarter-finals, semi-finals and finals (an A-Final and a B-Final), with the first finishers across the line advancing. A skater completes the distance when the leading tip of the blade reaches the finish line; the end of the race is declared by the Referee.

The general racing rule is that skaters must, by their way of skating, contribute to the honest, sporting and safe progress of the race so the result is decided on merit. Overtaking is allowed at all times, but until the skaters are level the responsibility to avoid contact or obstruction lies with the overtaking skater, provided the skater being overtaken does not act improperly. A skater about to be lapped must move to the outside and not interfere with the overtaking skater; a skater lapped twice must leave the race (recorded as DNF) unless still close to other racers.

Breaches of the racing rules (decided only when clear and obvious with no shared responsibility) fall into categories:

• OFF-TRACK: skating with one or both skates on the left/inside of the curve past the marking blocks.
• IMPEDING: impeding, blocking, charging or pushing another skater with any part of the body, or crossing another's course thereby causing contact (cross-tracking).
• ASSISTANCE: each skater competes as an individual; illegal assistance sanctions all involved (the team-mate push in a relay is exempt).
• KICKING OUT: kicking out a skate during the race - including at the finish line - or throwing the body across the line, causing danger. A detailed 'Guidance to the Racing Rules' is published in an ISU Communication.

In relays a skater is in the race and responsible for the team until relayed by a team-mate: the exchange is made by touch - a skater is not in the race until touched by, or having touched, the skater being relieved (usually a push from behind). A skater may be relayed at any time except during the last two laps, which must be skated by one skater; a warning shot marks the start of the last three laps. Inactive skaters must stay clear of the racing line inside the curves and may only leave that area to make an exchange. Relaying without an obvious touch, or relaying during the last two laps, is an infringement.

Relays are skated over 3000m (Women) and 5000m (Men) with relay teams of typically four skaters (five at senior World Championships). The Mixed Team Relay runs over 2000m (18 laps) with teams of two Women and two Men, following a fixed exchange schedule - first four segments of 2.5 laps, then four segments of 2 laps, always in the order Woman-Woman-Man-Man. If a skater falls, only a same-gender team-mate may cover the segment (with defined exceptions near a scheduled gender change and in the last 2.5 laps, when any team member may take the relay). Departing from the fixed schedule is an infringement.

Sanctions for racing-rule breaches are graded:

• Penalty: for an infringement of the racing rules; the skater/team is disqualified in that race and excluded from the next round of the distance.
• Yellow Card: for an unsafe, harmful or hazardous offence, for more than one Impeding/Kicking-Out penalty by the same skater in one race, or as otherwise specified.
• Red Card: for an infringement deemed dangerous or grossly negligent, for a second Yellow Card in the same event, or for a Code of Ethics violation around the race. Where a contact is the minor result of simultaneous actions with no impact on the outcome, the Referee may rule Shared Responsibility with no penalty.

Short track's distinctive remedy is advancement: a skater who was impeded by another - where that other skater received a penalty, yellow card or red card - and who was in first or second position at the moment of the infringement is advanced to the next round (or to the A-Final / B-Final as applicable), even though they did not finish in a qualifying place. The Referee may also advance an obstructed competitor at sole discretion in mass/pack situations. Advancement preserves the principle that the result is decided on merit and that a victim of a foul is not eliminated by it.

Skaters line up at the staggered starting dots. On 'Go to the Start' they must be fully equipped; an omission is a False Start for 'delaying the start' (a warning). A False Start also occurs when a skater puts the tip of the blade in the ice, leaves before the gun, or causes another to move. ISU events generally use a 'zero false start' procedure at the elite level: at major events one false start may be allowed for the race, but the next skater committing one is penalised and excluded; a skater who already had a 'delaying' warning is excluded on a further false start. If a skater is interfered with before the last block of the first curve, the field is recalled and restarted.

Both disciplines are run by a panel led by the Referee, who has overall authority, takes all decisions on disqualifications and sanctions, and may use video footage and instant replay to verify infringements and false starts. Long Track adds a Starter, a Finishing Line Judge (whose call decides the winner unless automatic timing applies), Crossing Straight Judges, Curve Judges, Lap Scorers and Timekeepers. Short Track adds Assistant Referees, Heat Box controllers and video review officials. Decisions are protocolled and, where automatic timekeeping is used, the recorded time decides ties.

Long Track skaters use clap (klap) skates - a hinged blade that detaches at the heel for a longer push - and aerodynamic skinsuits. Short Track skaters use fixed long-radius blades offset to the left for the tight corners and must wear compulsory safety equipment: a hard helmet, cut-resistant gloves, neck guard, shin and knee guards and ankle protection; the loss of compulsory or recommended safety equipment, or wearing it incorrectly, results in a penalty. In Mass Start (long track) skaters also wear helmets and transponders on both ankles for timing. Padding lines the barriers around the short-track rink.

Competitors must represent an ISU Member federation and meet ISU eligibility and anti-doping requirements. Entries to ISU Championships and Olympic Games are made only through the ISU Member and are governed by qualification ranking lists (SQRL) and World Cup classifications that set the field and quotas per distance and per nation. There are no entrance fees for ISU Championships. Skaters arriving late or unprepared at the start may be warned, marked DNS or disqualified by the Referee.

Single-distance results rank skaters by time (lowest first); ties are recorded as equal places, resolved where possible by photo-finish times in thousandths of a second. Multi-distance results use the samalog total (lowest total wins). In Mass Start and Short Track, ranking is by finishing position / sprint points, with non-finishers ranked by laps completed. A skater who fails to complete the last allround distance (DNF/DQ) is classified as if they had not started it. In Team Pursuit elimination formats, teams progressing to the next phase always rank ahead of eliminated teams.

Key context for the current and next cycle:

• The 2024 ISU Congress adopted the rules used through the 2025/26 season and the Milano Cortina 2026 Olympic Winter Games (Speed Skating and Short Track Special Regulations & Technical Rules, published 6 September 2024).
• The ISU has continued to standardise the Mass Start (16 laps with 3 intermediate sprints at laps 4/8/12 and a 60-40-20-10-6-3 final-sprint scale) and the Mixed Team Relay in both disciplines as Olympic medal events.
• Effective 12 June 2026 the ISU consolidated and re-issued the long-track regulations as the ISU Speed Skating Sports Rules (2026), applicable after the 2026 Olympics; core technical content (400m / 111.12m tracks, distances and the samalog system) is unchanged, with refinements to organisation, qualification and officiating detail.
