Agegroups
Determine the groups for starters at competitons, that they are fair in athletical manners across the participating riders.
- Body creation of hormones(testosterone, oestrogen) change the conditional aspects of riders. That happens during the first phase of pubescence, females: 11-12, males: 13-14. These ranges are compiled statistically, outliers may appear.
- At the age of ~13-14 the development of strength differs between sexes. (De Marées, 2002, S. 498)
- Riders that turn 11 must switch unicycle size (from 20" to 24") in racing. Note: they can optionally start using 24" at any age.
- Relays and group freestyle are divided based on the age of riders U15/15+. In pairs freestyle the intervals are even smaller.
- Seasons are twisted on northern or southern hemisphere.
- Different disciplines have different seasons. Outdoor disciplines (such as racing) typically have their season from spring to fall, whereas indoor disciplines (such as freestyle) can have an all-year-season.

The first day of the competition is used to divide starters into agegroups.
Note: The list of arguments is incomplete!
Pro:
- Minimize the gap of conditional differences (Fact 1)
Contra:
- Riders may change their uni during one season (if they turn 11) (Fact 3)
- Riders may ride in U15 in the beginning of the year and 15+ at the end of the year (think of relays, pairs and group freestyle) (Fact 4)
- Planning is a little harder due to varying agegroup assignment during the season (minor issue)

Use a fix date to determine the agegroup of a rider. This may be the calendar year or another fix date (e.g. 1st of april). This date may vary between disciplines.

Instead of dividing the riders into age groups, there is only juniors and seniors (U15/15+) that can be a fix date (e.g. calendar year). Within either juniors and seniors the division into startgroups is done, based on their athletic level. There are two different approaches:
- Quantifiable division:
This belongs to all cgs-disciplines. Starters can submit their latest achievements (e.g. 100m time) along with their registration. Startgroups are computed by that data.
- Qualifiable division:
In e.g. freestyle a list is been pushed out (once a year?) that lists groups with a certain amount of tricks. Starters can check which group they belong to and in which they start.
Pro:
- Minimize the gap of conditional differences (Fact 1)
- Relays and group freestyle work across the season. Pairs are sorted in accordingly (Fact 4)
Contra:
- The division into which startgroup a rider may change over the year.
- What happens if the athletic level of a rider changes significantly across the year?
Neither racing nor freestyle competitions are setup like this.
Solution 1
Unknown (Oh wait, do we voted on that?)
Either solution 1 or solution 2 has disadvantages and the division of starters into agegroups is still a hot topic in sportscience. Thus no resolution has been found yet. All other sports deal with the same dilemma.
Solution 3 obviously is new.
