Venue

1. All Track Racing Disciplines, as well as Track Coasting and Track Gliding, must be held on a standard athletics competition track. Exceptions are the 50m One Foot and the 30m Wheel Walk, which can also be held at an indoor athletics venue. The IUF Slalom must be held on a surface that has the same characteristics as a standard athletics competition track and therefore complies with paragraph 2.1. If the requirements cannot be fulfilled, the disciplines cannot be offered as official IUF Track Disciplines and this has to be announced accordingly before the competition.
   Note: If the track is outdoors, plans must be made to deal with inclement weather. Using an indoor track can eliminate this problem. The track must be available for enough days to allow for inclement weather.

2. Every track and field competition venue for athletics approved by a national athletics organization or higher is approved for official unicycle competitions.
   The essential criteria that such a venue must comply with are the following:

   1. Any firm, uniform surface that complies with the specifications for syntetic surfaces for athletic competition venues is permitted.

   2. The nominal length of a standard competition track is 400 m, it must be not shorter than 400.00 m and not longer than 400.04 m. It must consist of two parallel straights and two bends whose radii must be equal. The inside of the track must be bordered by a kerb of suitable material that should be coloured white, with a height of 50 mm to 65 mm and a width of 50 mm to 250 mm. The kerb on the two straights may be omitted and a white line 50 mm wide substituted.

   3. The measurement must be taken 0.30 m outward from the kerb or, where no kerb exists on a bend, 0.20 m from the line marking the inside of the track.

   4. The distance of the race must be measured from the edge of the start line farther from the finish to the edge of the finish line nearer to the start.

   5. In all races up to and including 400 m, each rider must have a separate lane, with a width of 1.22 m $\pm$ 0.01 m, including the lane line on the right, marked by white lines 50 mm in width. All lanes must be of the same nominal width. The inner lane must be measured as stated in pragraph 2.3, but the remaining lanes must be measured 0.20 m from the outer edges of the lines.

3. The track must be prepared with start and finish lines for the various racing events that are unique to unicycle racing (such as 50, 30, 10 and 5 meter lines).

4. For races that include at least one turn, the inside lane must be on the left in the direction of the race. The individual lanes must be numbered, starting with the left-hand lane as No. 1.

5. A public address system must be provided to announce upcoming events and race winners. Bullhorns are usually not adequate for the track environment.

Officials and Judges

1. The host must designate the following officials for all track events:

   • Track Director

   • Referee

   1. For races the following additional officials and judges must be designated:

   • Starter

   • Timekeeper

   • Finish Line Judge

   • Lane Judge

   1. For technical disciplines the following additional judges must be designated:

   • Technical Disciplin Judge

Communication

1. If a convention host advertises events for disciplines with the names of the ones detailed in this chapter, they must use the rules provided here. If hosts desire to do variations on these rules, for example by offering other unicycle classes or wheel sizes, the events must be labeled accordingly, i.e. “100m Unlimited” or “Track Coasting; Modified”. The host can also offer events for additional disciplines. In both cases, the events for modified disciplines and the additional disciplines, they cannot be considered official IUF disciplines. In cases such as this, hosts must remember to provide detailed rules for these events at the same time the events are announced.
   Note: Examples of modified discipline events would be Unlimited races, where races can be run on unicycles without any restrictions. An example of another wheel size category would be the 700c wheel category, where unicycle wheels must be greater than 618mm in diameter, have a maximum bead seat diameter (BSD) of 622 mm, and there are no restrictions on crank length.

2. A Host is allowed to make helmets and/or other safety equipment mandatory for the competition or individual disciplines but it must be announced when registration is opened and must appear as an extra point to check when the competitor registers.

Age Groups

1. The following age groups are the minimum required by the IUF to be offered at the time of registration for any Track discipline: 0-10 (20 Class), 0-13, 14-18, 19-29, 30-UP.

2. Convention hosts are free to offer more age groups, and often do.
   Example: A full range of offered age groups might look like 0-8 (20 Class), 9- 10 (20 Class), 0-12, 13-14, 15-16, 17-18, 19-29, 30-39, 40-49, 50-59, 60-UP.

3. All age groups must be offered as men and women age group.

Cross-Discipline Rankings

Race Configuration

1. Racing competition is held in two separate divisions: Men and Women. An exception are the relays, which can be mixed men/women according to 2B.2.7, 7.

2. There will be no mixing of age groups, or men and women (except for the relays), in heats except with permission from the Racing Referee.

3. Track events must have both a preliminary and final round.

Heat and Lane Assignments

The following heat and lane assignments must be used for Unicon and international competitions. Also for other competitions it is recommended to do the assignments accordingly. The rule is applied for each age group independently.

1. The riders with the fastest seed times will be placed in the last heat, the next riders in the second last heat, etc. until all riders are distributed over the heats.

2. In age group races the distribution is done according to the seed times. Riders for whom no seed times are given will be placed without time behind the rider with the slowest seed time. The order in which riders with the same time are seeded will be decided by lot.

3. In final races the distribution is done according to the times achieved in the age group races. The order in which riders with the same time will be seeded must be decided by lot.

4. The lane assignment in lane-bound races is carried out according to the subsection below.

5. In each heat at least three riders should be seated if possible; however, this number can be undercut due to cancellations.

Timing, Photo Finish and False Start Monitoring

1. A Fully Automatic Timing and Photo Finish System must be used for the track races at Unicon and is strongly recommended for track races at all other competitions. The system must have been tested, and have a certificate of accuracy issued within 4 years of the competition, including the following:

   1. The System must record the finish through a camera positioned in the extension of the finish line, producing a composite photo finish image of at least 100 images per second, ideally 1000 images per second. The image must be synchronized with a uniformly marked time-scale graduated in 0.01 seconds.

   2. The System must be started automatically by the Starter’s signal, so that the overall delay between the start signal and the start of the timing system is constant and equal to or less than 0.001 second.

   Note: A system that works not automatically at start and finish will not produce fully automatically measured times and therefore does not comply with this requirements.

2. The placing and times of the riders must be read from the Photo Finish image by means of a cursor with its reading line guaranteed to be perpendicular to the time scale.
   Note: In order to confirm that the camera is correctly aligned and to facilitate the reading of the Photo Finish image, the intersection of the lane lines and the finish line must be coloured black in a suitable design. Any such design must be solely confined to the intersection, for no more than 20 mm beyond, and not extended before, the leading edge of the finish line. Similar black marks may be placed on each side of the intersection of an appropriate lane line and the finish line to further facilitate reading.

3. The system must automatically determine and record the riders finish times and must be able to produce a printed image (in physical form or into a file) showing the time of each rider. Additionally, the system must provide a tabular overview showing the time or other result for each rider. Subsequent changes of automatically determined values and manual input of values (like start time, finish time), must be indicated by the system automatically in the time scale of the printed image and the tabular overview.

4. For the track races at Unicon a false start monitoring system, which is able to reliably detect a crossing of the start line before the start signal, must be used and is strongly recommended for track races at all other competitions.

Accuracy of Results

1. For all Gliding and Coasting disciplines where the distance is measured, unless the distance is an exact 0.1 meter, the distance must be converted and recorded to the next shorter 0.1 meter, e.g. 34.56 m must be recorded as 34.5 m. When two riders reach the same distance, it must be determined to be a tie and the tie must remain and gets published as such.

2. For all Slow disciplines and Stillstand, unless the time is an exact 0.1 second, the time must be converted and recorded to the next shorter 0.1 second. When two riders reach the same time, it must be determined to be a tie and the tie must remain and gets published as such.

3. For all other track racing events mentioned in this chapter, unless the time is an exact 0.01 second, the time must be converted and recorded to the next longer 0.01 second, e.g. 14.533 seconds must be recorded as 14.54 seconds. In the event that there is a tie where an award and/or a place in the final is at stake, if the performances in question were achieved in the same heat and a photo finish system was used, the image of this system must be used to decide on the placings. In this case, the note (Photo Finish: +0.00X) is printed on the results list next to the official time. In other cases it must be determined to be a tie and the tie must remain and gets published as such.
   Example: If two riders have reached a time of 0:07.08 and the image of the photo finish system shows a difference of 0.006 seconds, the following will be printed on the result list:
   

   1st Place	Rider 1	0:07.08
   2nd Place	Rider 2	0:07.08 (Photo finish: +0.006)

Wind Measurement

It is recommended to measure the wind speed for 100 m, 200 m, One Foot, Wheel Walk, Track Coasting and Track Gliding since tailwind can have a significant influence when the track is not ridden at least once complete. For Unicons such wind speed measurement is required. For World Records to be valid, there may not be a tailwind averaging more than 2 m/s during the period specified below. The following rules apply to wind measurement:

1. All wind gauge equipment must be IUF approved and manufactured and calibrated according to international standards. The accuracy of the measuring eqipment used in the competition must have been verified by an appropriate organisation accredited by the national measurement authority.
   Note: All WordAthletics certified devices are approved.

2. Non-mechanical wind gauges must be used.

3. The wind gauge should preferably be started and stopped automatically and remotely, and the information conveyed directly to the competition computer. A manual start and stop should only be performed if there is no other possibility. In any case, the responsible juge needs a separate instruction for the correct operation of the wind gauge.

4. The wind gauge must be read in meters per second, rounded to the next higher tenths of a meter per second, unless the second decimal is zero, in the positive direction. Gauges that produce digital readings expressed in tenths of meters per second must be constructed so as to comply with this rule.
   Explanation: This means that a reading of +2.03 m/s must be recorded as +2.1 m/s; a reading of -2.03 m/s must be recorded as -2.0 m/s.

5. The wind gauge is placed beside the straight, adjacent to lane 1 and 50 m from the finish line (200 m and 100 m) respectively 25 m from the finish line (One Foot and Wheel Walk). During the Track Coasting the wind gauge is placed beside the straight, adjacent to lane 1 and 50 m from the starting line. In all cases the measuring plane must be positioned at 1.22 m ± 0.05 m height and not more than 2 m away from the track.

6. The period for which the wind velocity must be measured from the start signal are as follows:
   100 m . . . . . . . . . . . . . . . 14 seconds,
   One Foot. . . . . . . . . . . . . . 8 seconds,
   Wheel Walk . . . . . . . . . . . . 8 seconds.
   For a 200 m race, the wind velocity must normally be measured for a period of 14 seconds commencing when the first athlete enters the straight. The measuring can also be startet automatically after 12 seconds from the start signal.
   For Track Coasting the wind velocity must be measured for a period of 15 seconds from the time when the athlete passes the start line.
