The participants competing in the 50 and 70km distances will carry all equipment needed to manage two tough days and one night outside in mountain terrain. Participants in the BAMM 30 distance get their tent and sleeping bags transported to the night camp. Therefore the BAMM 30 participants will most lightly have a slightly lighter backpack to carry through the course.

On Friday morning before the start the teams will receive the maps and courses and can start planning the best route. A collective start will then take place. After passing all the checkpoints the competitors will reach the night camp where everybody will spend the night in a big camp.

Day 2, the start will be a pursuit start for the top teams from day 1. The leading team starts first and after that the second team and so on based on the results from day 1. All teams arriving at the night camp more than 1 hour after the leading team from day 1 will have a collective start. The goal will be in Riksgränsen where a hot shower, sauna and mingle awaits. In the evening you can enjoy the price ceremony and dinner.

What distance/class is appropriate for me

This is the class for those wanting to try to hike or trailrun for the first time. There is no orienteering involved and the participants follow a marked route so there’s really no experience needed. In this class you run on your own and it´s perfect for those who wants to try a new running experience in the wilderness.

This class starts on Saturday so for those who wants we will offer a free guided tour on the Friday.

Some experience of mountain terrain, simple orienteering along or around trails and markers in the nature and often with clear terrain formations by checkpoints. If you feel comfortable hiking about 15km per day under 10 hours this is the distance is appropriate for you. A good distance if you are curious to try this type of competition for the first time.

Good mountain/nature experience. Puts higher demand on your ability to orient yourself mostly without path/trail and with “large objects” (peaks, lakes) as markers. This is the distance for the runner with good physical condition looking for a tough challenge.

Puts high demand on physical condition, mountain experience and ability to orient. We recommend first participating in BAMM 50 or having experience from similar races before taking on BAMM 70. This is the distance for the runner looking for a very tough challenge.


Distans Banlängd Klasser
BAMM 70 ca 70 km Male, Female, Mix
BAMM 50 ca 50 km Male, Female, Mix
BAMM 30 ca 30 km Male, Female, Mix
BAMM 10 10 – 15 km Male, Female,

You can choose between the distances 30km. 50 km or 70 km divided over two days. The distance is counted as the crow flies. The distances are divided in the classes, male, female and mix.

For day 2 there are also exercise classes. The exercise classes are available to make it possible for as many as possible to also participate in day 2 even if the team for some reason isn’t able to complete day 1.


Timing with SportIdent
SportIdent is the system used for clearing checkpoints och measuring time. It’s an electrical punching system where every participant uses a “punching stick” – the SI-stick which contains a RFID-chip. The chip stores the time and verification code from each checkpoint and the goal when the participant “punches” it at the checkpoints. Every punch is confirmed by a light and sound signal, no signal = no punch. The punch takes about 1 second, normally shorter. All the checkpoints look the same but have different functions: empty, verify, checkpoint and goal. Each team member has their own SI-stick that shall be mounted around the wrist with a bracelet supplied by the organizer. This is to be done before the start.

Before start
Before start the SI-stick must be emptied from old punches. This is done in an emptying unit located near the start area. Emptying the SI-stick can take a few seconds, wait for the light and sound signal confirming. When entering the start area all participants must pass a verifying unit that verifies that the SI-stick has been emptied. Light and sound signal = OK, no signal = SI-stick must be emptied.

During the race
Along the course all participants must punch the SI-stick in the checkpoints. It will be verified that the team members doesn’t punch with too long of a gap (see rules). The checkpoint units are attached to a piece of wood/stick along with an orienteering screen and a manual paper punch. If you don’t receive a light and sound signal when punching your SI-stick something is not working properly and the paper punch should be used instead. Punch the manual paper punch in your map.

There has been instances when checkpoints continue to sound. This is also a sign of malfunction and the paper punch should be used.

When passing the finish line you will punch in the goal checkpoint. At this moment the timing is stopped. Please proceed directly to the verification checkpoint, especially important on Saturday when the speaker will want to have your finish time as soon as possible. The verification unit is connected to a computer that reads the SI-stick and verifies that you have punched the checkpoints in the correct order and also giving you the finishing time. After the race is over the SI-stick should be returned to the organizers (if you are not using your personal SI-stick).
