The competitions

The IJRU world championships series is made up of the competitions International Open Tournament (IOT), Junior World Championships (JWC), Senior World Championships (WC), and Show Competition (SC).

Double Dutch Contest

In partnership with the Japan Double Dutch Association (JDDA), the Double Dutch Contest 2021 will be colocated with the IJRU 2021 series, run by and using the rules of the JDDA.

All competitions are single-round except the Senior World Championships, which has a two-round structure. Athletes compete in the first round (preliminaries) to determine the all-around and for a spot in the final round. The winner of the final round (finals) will be the world champion(s).

Divisions

Gender categories

For team events the gender categories are defined as follows

Category	Definition
Female gender	all female
Male gender	all male
Mixed gender	at least one male and one female
Any gender	any combination

Please refer to the current IJRU gender policy for guidelines on gender categories.

All single-participant events have a female gender category and a male gender category.

Except as noted below, all team events have a female, male and mixed gender category. In the mixed category, at least one female and one male athlete must compete in each event the team competes in. Failing to fulfil this criterion will disqualify the team from the gender category and if applicable, the All-Around and/or affected Overall.

The Show Competition and Double Dutch Triad events have an "any gender" category, with no requirement on the gender of the athletes. A team may consist of athletes of one gender only or of athletes of different genders.

There must be 4 or more entries from 2 or more countries in an event gender category for the event to be competed in that gender category. If an event has a gender category that fails to fulfil this requirement it will be combined or cross-ranked. The preferences of combining or cross-ranking gender category in order:

1. Male → Mixed
2. Mixed → Female
3. Female → Mixed

Combining entries

If two gender categories both do not have enough entries, they will be combined and ranked together, and rank will be awarded across all of the competitors in the combined gender categories.

If the combined gender category still doesn't meet the requirement, the combined category is cross-ranked.

Cross-ranking entries

If one gender category has enough competitors to compete but another one does not, the larger gender category is ranked and awarded as normal, but the smaller gender category is ranked combined against the larger group and only competitors that place against the combined ranked entries will be awarded. The combining to create the cross-rank is done once for the whole category, not once for every entry.

Example

If the Male gender category has the following results for a Single Rope Speed Sprint Event

Participant	Country	Score
A	Iceland	85
B	Greenland	84
C	Iceland	76

It needs to be cross-ranked, since it has fewer than 4 entries, despite having 2 countries.

The Mixed gender category it will be cross-ranked against has the following results

Participant	Country	Score	Rank
D	Antarctica	90	1
E	Iceland	83	2
F	Greenland	76	3
G	Madagascar	75	4

They would be combined and ranked to determine the cross-rank for the Male gender category as follows

Category	Participant	Country	Score	Rank
X	D	Antarctica	90	1
M	A	Iceland	85	2
M	B	Greenland	84	3
X	E	Iceland	83	4
X	F	Greenland	76	5
M	C	Iceland	76	5
X	G	Madagascar	75	7

And the following medals would be awarded:

• Mixed
  • 1st: D - Antarctica
  • 2nd: E - Iceland
  • 3rd: F - Greenland
• Male
  • 2nd: A - Iceland
  • 3rd: B - Greenland

Registration and qualification process

Qualification for World Championships Finals

The top 6 athletes/teams in every event in the World Championships all-around/preliminaries (first round) qualify for the World Championship Finals.

Re-competing the SRSE 1x180 or SRTU Triple Unders events in Finals will be optional for athletes who qualify. Athletes who qualify will have 15 minutes after the qualifiers are announced to decide whether they will re-compete either or both events in the Finals, or whether they choose to keep their qualifying score instead. The athlete, and the national head-coach (or head of delegation) will have to provide a signature confirming the choice(s) that they have made. Once the declaration is made, the decision is final, and changes will not be allowed. Any athlete who chooses to re-compete an event will be expected to do so.

Any athlete who withdraws ("scratch") from one of these events after deciding to re-compete will be disqualifying themselves from that event, and their qualifying score will not be considered in the results to decide the winner.
