Ski techniques
Participants may use the cross-country technique of their choice. Competitors must not skate in the classical tracks. On most parts of the route there are classical tracks wherever possible.

Freestyle
On all sections marked with a green sign, any style may be used. Freestyle is permitted on the left-hand side in the direction of the race.
In narrow areas, no differentiation can be made, so freestyle applies.

Classical
Tracks for classical skiing are on the right-hand side in the direction of the race. The sections with separate tracks for classical skiers are marked by red signs. Skating is forbidden in these sections. Any skiers who fail to comply with this rule may be disqualified.

Start 
All participants must decide before the start how they wish to ski the first kilometres. The start will be split according to technique. Freestyle applies left of the corridor, and classical technique on the right, next to the ladies’ starting area. Changing technique in the first kilometres is not possible as there are barriers between the two kinds of tracks.

Race distance
Competitors who have registered for 42 km are allowed to finish the race after 21 km in Pontresina. The will be officially ranked for the half marathon. Participants who have registered for 21 km must finish the race in Pontresina. Otherwise they will be ranked neither for 21 km nor for
42 km.

Ascents / Descents
Competitors must cover the whole distance on skis. Removing skis, especially for ascents, is not permitted. Participants who do not comply with this rule may be disqualified. An exception to this rule is the descent in the Staz forest where participants may take off their skis and walk down the especially marked footpath.

Ski equipment – change of skis

• Skis and poles must comply with International Ski Federation (FIS) guidelines.
• Changing skis during the race is forbidden. If a ski or binding is defective, only one ski may be changed.
• Due to ecological reasons the race stickers will no longer be sent to the participants automatically. However, you will receive a freesticker at the disribution of the starting numbers if you wish to have one as souvenir.

Competitor in the competition
Competitors must cover the whole distance by their own strength. The help of pace-makers or helpers pushing from behind is not permitted (ICR 340.1.1).

Starting groups
Competitors must start in the allocated starting group. The classification for a category remains valid for two years, no matter whether or not you participate this year. First time competitors who offer proof of ranking with their entry may be allowed to start in a front group.

Ranking

Last passing times for course sections and the finish

• The route is checked by a sweeping car.
• The finishing area will be closed at 4 pm (42 km) / 2 pm
  (21 km). Participants who arrive at the finishing line after the official closing time will not be ranked.
• Last passing times for 42 km: Pontresina 12.45 pm, La Punt 2.15 pm and Zuoz 3 pm
• Participants overtaken by the sweeping car after Pontresina are not allowed to continue the race and have to return their chip for time measuring immediately to the sweeping car driver. From Pontresina, La Punt and Zuoz an official bus takes these participants to the finish area where they can collect their bags for personal belongings.
• Marathon participants arriving in Pontresina after 12.45 pm will be directed into the finish there and will be ranked in the half marathon.
• The jury reserves the right to extend the last passing and closing times in case of difficult conditions.

Disqualification
Participants are disqualified and not allowed to compete for the next two years, if

• they compete with a starting number other than their allocated number
• they compete under a false name
• they give their starting number to another person
• they start from a starting area other than their allocated starting area
• they cause a false start
• they cover part of the route in another manner than on skis. Exception: Descent in the Staz forest on especially marked footpath.

If competitors are banned for two years, they automatically lose their original starting qualifications and are relegated to the next starting group.

Appeals
Appeals must be submitted to the jury in writing. A charge of CHF 100 will be levied. Appeals may be accepted from male elite skiers until 15 minutes after the arrival of the 100th male participant, from female elite skiers until 15 minutes after the arrival of the 20th female participant. Appeals from all other participants will be accepted until 15 minutes after the official closing time.

Doping checks
