Keeping to certain guidelines and standards, each WSFed certified contest finds its best slackliners. There are different contest categories for slackliners of different abilities and for organizers with different resources. Each contest category has suitable guidelines for slackline setup, worldranking points, prize money and judging,


One round of a WSFed slackline contest lasts around an hour. This helps to maintain spectator attention. With pauses between the rounds a contest can spread over a couple of days. In a one day meeting, pauses give the public chances of a break, or of participation in a supporting program.

Category overview

WSFed certifies slackline contests in five categories. The certification ensures to set certain standards and provide a high quality within the contests. Based on the various categories, the athletes can win a different amount of world ranking points:

1.) Slackline World Championship
The World Championship in trickline is held only once per calendar year. The organizer invites the top eight available athletes in the world ranking to participate. This guarantees the highest level of Slacklining. Furthermore there is a special competition modus in which the slackliners have to approve their skills in a group phase before they can reach for the trophy.
The World Championship is particularly interesting for the media and the public (live and online), due to the participation of highly qualified athletes.

2.) National Slackline Championship
Each country can organize a national slackline championship once a year. In a national championship, only athletes from the given country may compete and the winner knows that there is no better slackliner around.

3.) Slackline WorldCup
At most five WorldCup competitions are held, each year. They are the contests where high prize money and the most world ranking points can be won. The WorldCup has taken place since 2010; so it is the oldest international slackline contest series. This means that the WorldCup is highly respected by athletes and by the media.

4.) Slackline Open
The amount of Slackline Open is limited by 20 per year. WSFed hopes and expects that Opens will have international participation. For this reason, Opens rank higher than National Championships, as regards world ranking points. The organization rules are less strict than those of the WorldCup, so that the costs can be kept significantly lower.

5.) Slackline Jam
A slackline jam is the simplest way to have a WSFed licensed contest. Relatively few world ranking points are given here, so the rules can be kept simple. This gives small meetings the chance through WSFed licensing to make contests more interesting for the athletes, and thus to raise the standard. Any number of slackline jams can be organized.

Regularly the contests are divided in separate contests for men and women. If there is no separate contest for women, they are allowed to compete in the men contest. For appointing the qualified (invited) slackliners, the two world ranking lists are merged and the points are considered no matter what sex.

Contest Procedure

Usually (Exception: World Championship) a contest is organized as a series of 1 against 1 K.O. "battles". Two slackliners compete for a given time. One starts his (or her) performance. If he falls off the line or jumps down from it, the opponent takes over. When the second one leaves the line, the first takes over again. This "battle-mode" is stimulating for the athletes and for spectators, as the slackliners inspire each other to show better and more spectacular tricks. After each round, the jury decides which of the two has won the "battle". He goes on to the next round, while the loser drops out. But the losers of the two semi-finals should compete against each other for third place, before the contest final.

Such a contest should involve 8 to 64 athletes. To avoid early elimination of strong contenders, the best slackliners (according to ranking) are seeded. The remaining competitors are deployed randomly. If too many athletes register for the competition, some should be eliminated in preliminary qualifications.


The Battle (1 vs. 1):

Before the battle begins the participants have to decide who goes first on the line (“stone paper scissors”). Each competitor has a certain time allowance, to show the judges his prowess and so to win against his rival. His time runs whenever he is on the line. When he falls off or steps down, his rival should be ready to start. When his time runs out, the athlete can complete his last trick or combo. But he must avoid exceeding his allowance by more than 15 seconds


During the battle, three qualified judges allocate points in different categories. At the end of the battle, each judge must decide, using his point allocations, who has won. Whoever gets the vote of the majority of the judges is then declared as the winner.

Tricklining is a competitive sport, where the whole performance brings the victory. The trickliner, who completes the most and the hardest tricks and combos in the allotted time, is the winner. The athletes and the judges must pay attention to difficulty, technique, creativity, amplitude and performance.

Time Control

Each trickliner during a battle has limited time to show his skills to the judges. To fit his tricks and combos into the remaining time, he needs to see on a monitor how long he still has, or else the moderator should inform him. There should be an acoustic signal when the time of a contestant runs out and another, longer one after the additional 15 seconds.

The time limit is interesting for spectators too. Tension builds up towards the end of the battle, and the most difficult tricks can then be expected, as the trickliner tries to decide the round in his favor.


The spectators, even if non-expert, should be aware all the time of the current state of the contest and the results of individual rounds. So the following should be displayed:
A list of starters showing their progress from round to round (as a table)
The time still available, alongside the name of the slackliner
The full results


The athletes build the accompanying music into their performances. This improves the entertainment and the mood of the public, turning the sport show into an emotional happening. It is recommended that a DJ should control the music. He can then attune the music to the mood of the athletes and spectators.


Moderators are a vital component of the contest. They entertain, animate and lead the public through the competition. As well as specialist knowledge, they must have the ability to judge and steer the mood of the public. They are largely responsible for maintaining the entertainment aspect of the competition. Meanwhile they must cooperate with the athletes, the DJ and the judges (the moderator has to wait for a signal from the head of the judges before he gives the go for the next battle). They inform the athletes about their remaining time and announce the judges' decision after each battle.


The location of a competition should suit the urban character of the sport. There must be enough room for the contest area and for spectators. Furthermore, there should be room for a supporting program. As slacklining is a very versatile sport, that anybody can quickly learn, the spectators should also get the chance to try slacklining for themselves.

Supporting Program

The supporting program of a slackline contest can be very diverse. Anything goes: other sports, slackline participation, concerts, after-show-parties, sponsor presentation stands, eats and drinks, etc. The contest can be embedded in a program directly related to the contests. But the supporting program can instead expand the contest into a, festival lasting several days. WSFed can advise on this according to the contest involved.

Fee / payment

For the assignment of contest license a licensing fee will be charged. The fee has to be paid beforehand. The license will be valid right after the license fee is paid. Any costs which may arise due to the money transfer have to be paid by the contender. For payments out of EURO-countries please use the updated daily exchange rate.

Photo and video material

The WSFed has the right to create own photo and video material at each WSFed contest.

The organizer must ensure that all participants agree to let the WSFed make full use of any artwork as a result of the event and reserves the right to use this material without further agreement by the participants.

Advertising space

The WSFed has the right to place at least 2 banners (or similar) at each WSFed contest.

Special regulations

The participants of a competition are not allowed to finish their run before the time is up. If a contestant cannot continue (e.g. in case of injury) he gets disqualified and his opponent goes on to the next round.

Each competitor has the right of one injury lay-off at each tournament. This break can be 2 minutes maximum and should be used for medical treatment or like that. The break needs to be announced to the head of the jurors.

The head of the jurors is authorized to disqualify a competitor in case of health threat, even against his will.

Behavior in case of absence of a contest participant:
In case of absence after the registration (before the contest) and before the sign in:
The participant will not receive world ranking list points; his competitor receives a bye for the next round. If the reason of the absence is indefensible, the athlete will get a suspension for WSFed competitions (6 – 12 month). During this suspension the athlete can take part in competitions, but neither will get the points, nor is listed in the world ranking list.

In case of absence after the sign in (on site):
The athlete receives the world ranking list points; his competitor receives a bye for the next round. If the reason of the absence is indefensible, the athlete will get a suspension for WSFed competitions (6 – 12 month). During this suspension the athlete can take part in competitions, but neither will get the points, nor is listed in the world ranking list.

In case of absence/injury during the competition:
The athlete receives the world ranking list points he scored until his absence/injury; his next competitor receives a bye for the next round.
