Freestyle competitions are a chance for riders to show off their artistic side. Set to music, competitors choreograph a routine complete with showmanship and a costume. Freestyle routines are done either individually, in pairs, in groups, or as a club. Also in the Freestyle category will be X-Style, which uses a different judging system.

To allow riders to compete against others who are at a similar skill level, the individual and pairs competitions are split into three categories: novice, intermediate and expert. To determine proper category placement, riders can use the USA Skill Levels as a guide.

novice (level 1-3)

intermediate (level 4-6)

expert (level 7+)

The freestyle competitions are judged equally on both technical skill and artistic presentation.

Individual Freestyle:

The time limits are as follows: novice (2 minutes), intermediate (3 minutes), expert (4 minutes).

Pairs Freestyle:

The time limits are the same as for the individual freestyle competition.

Group Freestyle:

This is a competition for groups of 3 or more riders not necessarily associated with a single club. A rider may perform in only one group routine. The time limit is 3 minutes.

Club Freestyle:

Each USA-affiliated club can field one group of 3 or more riders for this competition. The time limit is 5 minutes.


X-Style is an event for riders to show off their highest level and most favorite skills. Riders mix together freestyle and flatland skills with creativity and ingenuity. The competitors are judged solely on the skills that they complete. Presentation and falls do not count like in other Freestyle competitions.

In X-Style, starting groups of ten or fewer riders compete against each other, and the top three riders advance to the next round. In prelims, riders are given a minute and a half to show off their best skills. In the final round, the top riders compete against each other with a two-minute run. Judges will be selected from other starting groups or from non-competing volunteers.


The muni competitions include those events held outside on trails using a mountain unicycle.

Required safety gear: shoes, knee pads, gloves (or wrist guards), and helmet

Cross Country

This is an endurance race on mountain bike trails. There are separate races for beginner, advanced, and elite.


Riders get two chances to complete an uphill course in the fastest time. If you fall, you can remount at the same point or lower than where you fell. There are separate courses for beginner, advanced, and elite.


Riders get two chances to complete an downhill course in the fastest time. If you fall, you can remount. There are separate courses for beginner, advanced, and elite.


Cyclocross was held for the first time at NAUCC 2013.  It’s an exciting race where riders traverse multiple laps of a challenging grass course including steep uphills and downhills, bumps, and obstacles that require you to dismount and carry your unicycle over them. The winner is the one who can do the most laps. There are two categories for Cyclocross: Unlimited and Standard. Unlimited is for wheel sizes 29 and bigger or any unicycle that is geared. Wheels are measured by rim size.

Track Events

The track competitions include typical track races, some specialized unicycle races, and the obstacle course (IUF Slalom). All of the track races have a maximum wheel size and minimum crank length. There is box that your tire must fit inside for the unicycle to be legal. For most riders, the wheel must not be more than 24”, and the crank arm length must not be shorter than 125mm. For riders 10 years of age or less (who choose to ride in the 20” category), the wheel must not be more than 20”, and the crank arm length must not be shorter than 100mm. All races will be started using a starting gun. Each rider is allowed one false start. A false start is classified as when the front of a rider’s wheel crosses the line before the starting gun goes off. After two false starts, the rider will be disqualified from the race.

After all of the age heats have run, the fastest eight males and the fastest eight female riders will ride the race again in an expert heat. The winner of the expert heat is declared the North American Champion of that event. There are expert heats for all of the races except for the Obstacle Course, where the top times are tabulated to determine the overall winners.

Required safety gear: shoes, knee pads, gloves, and helmet.

NOT ALLOWED: Studded Pedals, Metal on seats or anything other than plastic seat holds.


In the 800m race you are allowed to remount. In all other races a fall disqualifies you. Races are run in heats by age category starting with the oldest age category first.

30m/10m Wheel Walk:

In this race you walk the wheel for 30m (10m for the youngest riders). Crank arm length does not matter for the wheel walk race.

50m One Foot:

In this race you ride one footed, and will have to be transitioned into the skill before a marked line which is 5m from the starting line.

IUF Slalom: (Obstacle Course)

You have two tries to negotiate a path around a set of traffic cones in the shortest amount of time. You are allowed to hit the cones, but not knock them over. You may have a practice turn before you go for a time, but you have to establish that it is either for practice or to be timed with whomever is timing before you begin the course.

Distance Riding

The road races are held outside on bike paths or on the street using a geared or ungeared large-wheel unicycle (unlimited category) or a standard 24” unicycle for the 10k or criterium (standard category).

​Required safety gear: shoes, knee pads, gloves, and helmet

Distance Racing events include:


The 10k race covers a distance of ten kilometers (6.2 miles) on open roads. There are separate categories for large wheels and standard 24” wheels (20” for the youngest riders).


The criterium typically covers a distance of 5k to 10k by doing multiple laps around a technical course. This format makes the race fun for the spectators. There will be three categories for standard, unlimited and 20″ for the youngest riders.


This year’s marathon will be held during Hines Park Bike Day, which is held every Saturday in the warmer months. During bike day, the roads are completely shut down to motor vehicles. Although the route is rather flat, spectators and spotters will have access to the entire route, allowing for quick response times to injuries.


The Urban competitions include those events held outside on pavement using a trials or flatland unicycle and man-made obstacles.

Urban events include:


In the flatland competition, riders compete to do the best tricks on flat pavement. There is a preliminary round to decide who will compete in the final, and a battle-style final round. There are separate categories for Advanced, Jr. Expert, and Expert.


In street, riders compete to do the best tricks using a set of urban-style obstacles (boxes, stairs, rails).  Usually, there are three “zones”, and multiple riders compete, taking turns. There are separate categories for Advanced and Expert.

Urban Destination

There’s a new event at NAUCC this year!
We’re introducing a new event we’re calling “Urban Destination”. In short, it’s an urban take on the standard uni tour of the city. Riders will be traveling together, via bus, and be competing in trick challenges or small informal competitions at the various riding spots throughout the day, and seeing some of the sights of the Ann Arbor area!

It is recommended that you are comfortable riding in an urban/street setting, or an extreme willingness to learn. In order to compete in the challenges/competitions, you MUST be wearing a helmet! If you would like to attend this event, it is an extra 5$ when registering.


Required safety gear: shin pads and helmet for all urban events


A trials course consists of a large number of “lines” which are specific paths to take over a set of obstacles. For example, a line might include hopping onto a box, riding across a skinny rail, then hopping to the ground. Riders compete to complete as many lines as possible in the time allotted. There are separate categories for Beginner, Advanced, and Expert.  Advanced and Expert share the same more difficult course.  Beginners are allowed to get a helping hand.

Required safety gear: shin pads, gloves, and helmet

High Jump

Riders compete to see who can jump with their unicycle over the highest bar.  You must ride at least one revolution after you land to show you are in control.
Required safety gear: helmet

Long Jump

Riders compete to see who can jump the farthest horizontal distance. You must ride at least one revolution after you land to show you are in control.
Required safety gear: shoes and helmet


The 2017 USA Rulebook Amendments describes the set of rules to be used for American unicycling competitions. The 2017 Rulebook Amendments cannot be used as an independent document; they must be used in conjunction with the 2017 IUF Rulebook. This document describes where the Unicycling Society of America chooses to differ from the IUF Rulebook for their competitions.
