Cross-country skiing: two techniques, many race formats.

The rulebook and its edition

FIS ICR Book II covers cross-country. The copy read for this site is marked "EDITION October 2023" (FIS's file name says 2024). A 2025 edition is referred to elsewhere but was not found, so every rule below is from the October 2023 text unless another document is named. The current ICR and the race jury decide.

Two techniques

Article 310.2 defines two techniques. In classical technique, single or double skating is not allowed. Free technique includes all cross-country techniques. The jury may ban or require particular techniques on marked sections of a course. This site describes what the rule says, not how either technique is skied.

Race types and lengths

Article 310.1 sets the competition types and their lengths:

• Distance races: 5 km to over 20 km.
• Individual and team sprints: 1.0 km to 1.8 km.
• Relays: up to 10 km per team member.

Courses are described by three measures: height difference (HD), maximum climb (MC) and total climb (TC) (art. 311.2.4).

The championship programme

Article 310.3.1 sets the programme for the Olympic Winter Games and the World Championships, the same for women and men, with the techniques alternating between editions:

The World Cup programme, distances and techniques are set by FIS each year (art. 310.3.2). Junior and U23 World Championships use a 10 km interval start, a 20 km mass start, a sprint and a 4 x 5 km mixed relay in which women and men alternate (arts. 310.3.3 and 310.3.4).

At the Olympics

FIS listed 12 cross-country events at Milano Cortina 2026, six per gender: sprint classic, 10 km interval start, skiathlon, team sprint free, 4 x 7.5 km relay and 50 km mass start classic. FIS named equal race distances for women and men among its innovations for those Games. The races were held at Tesero; results are on Milano Cortina 2026. Men raced cross-country at Chamonix in 1924; Olympedia records the 50 km there on 30 January 1924. Olympedia says the first Olympic cross-country event for women was the 10 km at Oslo on 23 February 1952.

Equipment, in brief

FIS's equipment specifications for cross-country, ski jumping and Nordic combined carry "EDITION 2026/2027" on the cover, but the FIS-hosted file is a marked-up version, so the figures below should be checked against a clean copy.

• Banned: anything that affects or enhances the natural push-off, such as springs or mechanisms in skis, poles, bindings or boots; outside energy sources; anything that changes the track or snow to rivals' disadvantage; and anything that raises injury risk in normal use (B.1.1).
• Racing skis must keep the basic geometry of commercially available skis, with a minimum length of the skier's height minus 100 mm; both skis must be built the same way and be the same length (B.2.2). A pair must weigh at least 750 g without bindings (B.2.2.3). Scale or step patterns are allowed as climbing aids (B.2.2).
• Two poles of equal length, one per hand. The maximum length is 83% of the competitor's height (measured in ski boots) in classical technique, except at popular races, and 100% in free technique; telescopic poles are not allowed (B.5.2 and B.5.3).
• New equipment must be submitted to both FIS and the International Biathlon Union by 1 May of the year the season starts, so that one approval applies in both sports (B.1.2).

Fluorinated wax is banned in all FIS disciplines under ICR 222.8, and FIS says use in competition leads to disqualification. FIS's official result list for the Olympic women's sprint classic qualification at Tesero on 10 February 2026 records two disqualifications under that rule. The ban and its dates are on wax and the fluor ban.

A separate code for trail users

On 6 September 2023 FIS released a ten-rule Cross-Country Code of Conduct, saying not all rules of its general code for skiers and snowboarders apply to every discipline. It covers respect for others and signs, choice of tracks, overtaking, encounters, poles, speed control, keeping the trail clear, accidents and identification. Both codes are compared on the codes of conduct.

The 2026-27 season

On 24 October 2026 the cross-country World Cup had not started. FIS's calendar announcement of 11 May 2026, subject to Council approval, has it opening at Ruka, Finland, on 27 November 2026, with the Tour de Ski starting at Les Rousses, France, on 1 January 2027, and the finals at Ulricehamn, Sweden. The 2027 Nordic World Ski Championships are at Falun, Sweden, where FIS documents give different dates; see world championships.
