1. Race Format

1.1 Objective

The goal is to navigate the entire course as quickly as possible – or reach the furthest point possible and finish within the time limit.

1.2 Duration

The aim is to complete the course within 100 hours (4 days + 4 hours).

  • If a team’s finishing time exceeds 100 hours but is no more than 100 hours and 15 minutes, one checkpoint will be deducted from the team’s total score.

  • If a team’s time exceeds 100 hours and 15 minutes, it will not get an official result.

1.4 Results

If several teams complete all checkpoints in numerical order within the time limit, the fastest finishing time determines the ranking.

If several teams do not finish the full course but collect the same number of checkpoints in numerical order, the winner is the team that has collected more bonus checkpoints (see section 2.1).

If teams have the same number of checkpoints in numerical order and bonus checkpoints, the finishing time decides the ranking.

Penalties for late arrivals or rule violations may affect the total number of checkpoints or the final time (see section 8.1).

2. Course

2.1 Checkpoints and punching

Checkpoints are marked in the terrain either with:

  • wooden plaques approximately 15 × 25 cm with yellow marking tape, or

  • orange-and-white orienteering flags.

Samples of both checkpoint types are displayed at the event centre.

Checkpoints must be collected primarily in numerical order. If a team abandons the numerical sequence, it may, on the way to the finish, collect bonus checkpoints it hasn’t visited before . These bonus checkpoints may be collected in any order.

Before crossing the finish line, each team must visit the last checkpoint (about 200 m from the finish).

To prove visiting a checkpoint, teams must punch their control card:

  • At wooden-plaque checkpoints, record the two-letter code using the team’s own pen.

  • At orienteering-flag checkpoints, use the punch marker provided.

If a team cannot find the punch (or the plaque/flag) but believes it is at the correct location, it may prove the visit by taking at least two photos of the location and team members (excluding the photographer).

All team members must be together within 5 metres of the checkpoint when punching.

Some checkpoints require a watercraft to reach them. These checkpoints are indicated in the descriptions and marked on the map.

2.2 Staffed Checkpoints

Some checkpoints are staffed. All instructions given by the checkpoint marshal must be followed.

Instructions may include signs attached to the flag, for example requesting participants to wake the sleeping marshal. Marshals may, for example, inspect participants’ gear.

2.3 Watershed Crossings

When crossing a watershed marked on the map, the boat and paddles must be disinfected before launching into the next drainage basin.

Disinfection may be skipped only if the boat is not launched into water in that drainage area.

The team’s route may be checked afterwards. Failure to disinfect will result in a minimum two-hour time penalty.

2.4 Restricted Areas

Private yards are strictly off-limits. Some other restricted areas are also marked on the map.

Wilderness huts may not be used for overnight stays indoors, as they are not intended for commercial events. In emergencies, sleeping inside a hut is permitted.

3. Teams

3.1 Team Composition

Each team consists of 2–5 members.

The team’s official time is recorded when the last member crosses the finish line.

If a member must withdraw, the team may continue only if:

  • The safe return of the withdrawing member is ensured, and

  • At least two members remain, and

  • The Race Director grants permission to continue.

3.2 Moving as a team

The team must stay together for the entire race, with all members remaining within sight and calling distance at all times.

4. Equipment

Teams must bring all equipment they carried at the start back to the finish.

4.1 Mandatory Equipment

A full list of mandatory equipment is provided on a separate page.

Some items (e.g., whistle) must be carried at all times; others (e.g., watercraft) may be temporarily left in the terrain. Details will be provided in the checkpoint descriptions.

4.2 Prohibited Equipment

A list of prohibited equipment is provided on a separate page.

5. Assistance and Support

5.1 External Support

Teams are not allowed to use external support or assistance during the race, except for services provided by local shops and restaurants.

No items may be placed in the terrain before the race begins.

5.2 Other Teams

Teams may assist other teams if they wish, but such assistance must be offered equally to all teams in the same situation.

6. Emergencies and Communication

6.1 Emergencies

In emergencies, every participant is obliged to help an injured or ill person, even if they belong to another team.

Time spent helping will be credited in the results where possible. Failure to assist will be penalised.

Organisers and checkpoint marshals have the right to order a team to rest for a set time or withdraw from the race if it is deemed necessary for safety reasons.

6.2 Communication

Teams may use mobile phones only to:

  • Request assistance or evacuation of an injured participant.

  • Report a danger observed in the terrain that threatens participants.

  • Inform organisers of a team decision that might otherwise trigger unnecessary rescue operations.

7. Environment

7.1 Leave No Trace

Participants must move through the terrain with respect for nature and minimal impact.

All litter and non-biodegradable waste must be carried to the finish or disposed of in designated bins.

7.2 Open Fire

In the wilderness area, making fires is permitted with due care and safety.

If a forest fire warning is in effect at the start of the race, no open fires (campfires, twig stoves) may be made unless organisers announce a change in the situation.

8. Violations

8.1 Rule Violations

Breaking the rules will result in a penalty determined by the Race Director:

  • warning

  • time penalty

  • deduction of checkpoints from the score

  • disqualification

If time penalties push a team’s official time beyond 100 hours and 15 minutes, the team will still receive a result (unlike teams whose actual finishing time exceeds 100 hours and 15 minutes).

8.2 Protests

A team may file a protest if it believes it has received an unjust or disproportionate penalty.

Protests must be submitted in writing to the Race Director within one hour after the race ends.

The Race Director will hear the protesting team and other relevant parties before making a decision. The Race Director’s decision is final.
