3.1 Course Design Principles
FIS-homologated courses must provide a balanced test of uphill, flat, and downhill ability. The course profile should include approximately one-third uphill, one-third flat, and one-third downhill terrain, ensuring no single physical attribute dominates.
3.2 Course Specifications by Distance
- Sprint (1.0–1.8 km): Total climb 30–60 m (98–197 ft). Maximum single climb 30 m (98 ft). Course designed for spectator-friendly layout with multiple passing opportunities.
- 10 km: Total climb 250–420 m (820–1378 ft). Maximum single climb 50–80 m (164–262 ft). Laps of 2.5–5.0 km.
- 15 km: Total climb 400–600 m (1312–1968 ft). Maximum single climb 80 m.
- 30 km: Total climb 800–1200 m (2625–3937 ft). Laps of 7.5–15.0 km.
- 50 km: Total climb 1400–2000 m (4593–6562 ft). Maximum single climb 100 m (328 ft).
- Altitude restriction: Maximum course altitude 1800 m (5906 ft) above sea level for World Cup and Olympic events
3.3 Track and Course Width
- Classic technique: Minimum 3 m (9.8 ft) wide, with machine-set parallel tracks (2 tracks standard, 3 on uphills for overtaking)
- Free technique: Minimum 6 m (19.7 ft) wide, groomed flat surface without set tracks
- Mass start: Start area must be at least 10 m wide to accommodate field safely
- Course marked with directional arrows and distance markers every 1 km
3.4 Stadium Area
- Stadium must accommodate: start area, finish area with electronic timing, penalty loop (for sprint), warm-up area, wax cabins, and spectator zones
- Finish straight: minimum 100 m long for distance races, with photo-finish camera and electronic timing mat
- Exchange zone (relay): 30 m long, clearly marked with entry and exit gates
- Transition zone (skiathlon): designated area for ski and pole change, minimum 15 m long
