Proposal 27: Revise 2B.8.1 IUF Slalom [ Revision 7 ]

Committee: Track
Submitted on 2023-08-15
Status: Passed on October 09, 2023

Background

The current rule on IUF Slalom has some shortcomings that have been worked out and discussed in discussion 70. These include:
1. safety concerns due to objects in the area behind the finish line.
2. handling of flying starts and their monitoring
3. alignment of the cones
4. practice course

The rule has been extended with regard to this aspects.

Proposal

Revision of the Rule: (As PDF Version with changes highlighted)

Old Rule:

2B.8.1 IUF Slalom

Pictured here is the IUF Slalom, in which you must ride around 10 cones in the correct pattern. Arrows marked on the ground should indicate the direction of the turns for riders unfamiliar with the course. The rider has to start directly behind the Start line. The Starter gives the opening, and then the competitor has to start during the next 3 seconds. The timer is started when any defined point of the tire (for example the part that crosses a low light beam) crosses the start line, and stops when a similar point of the tire crosses the finish line. If the rider has not yet started after 3 seconds, the timer will start counting anyway. The rider is not disqualified for this. Time measurement at start and finish line must be identical to insure accurate time measurement. It must be secured that riders do not gain momentum before crossing the start line (no flying starts). Remounting is not allowed. Cones may be hit, but not knocked over. The course must be followed correctly, including the direction of turns. The last cone must be completely circled before the rider's time is taken at the finish line. Riders who go the wrong way around a cone can go back and make the turn the correct way with the clock still running. The cones used are plastic or similar material traffic cones. Cones must be between 45 and 60 cm tall and the base plate must fit in a square with side length 32 cm.
Note: The cones should be stable enough to stay put even in a stiff wind.
The course must be set up accurately. The proper positions of the cones should be marked on the ground for a cone to be replaced quickly after it has been knocked over. Riders get two attempts.

New Rule:

2B.8.1 IUF Slalom

1. The IUF Slalom is a parcours consisting of 10 cones, as shown in figure 2B.1, which must be run through as fast as possible in the correct pattern, without knocking cones over. No remounting after a dismount is allowed. Riders get two attempts.

2. The rider has to start directly behind the Start line. The Starter gives the opening by indicating the start of the 3-second time window to cross the start line. The timer is started when any defined point of the tire (for example the part that crosses a low light beam) crosses the start line, and stops when a similar point of the tire crosses the finish line. If the rider has not yet started after 3 seconds, the timer will start counting anyway. This does not invalidate the attempt. Time measurement at start and finish line must be identical to insure accurate time measurement.

3. It must be secured that riders do not gain momentum before crossing the start line (no flying starts). If a flying start occurs, the start must be aborted by a clear and predefined signal. Flying starts can be automatically detected and signalled to the rider, e.g. by a light barrier system behind the rider at the start or by the responsible judge. If this happens the first time during an attempt, the rider is allowed to start over, but if it happens the second time, the attempt is invalid.

4. Cones may be hit, but not knocked over, otherwise the attempt is invalid. The course must be followed correctly, including the direction of turns. Riders who go the wrong way around a cone must go back and make the turn the correct way with the clock still running, otherwise the attempt is invalid. Arrows marked on the ground should indicate the direction of the turns for riders unfamiliar with the course. The last cone must be completely circled before the rider’s time is taken at the finish line.

5. The cones used are plastic or similar material traffic cones. Cones must be between 45 and 60 cm tall and the base plate must fit inside a square with side length 32 cm. The cones should be stable enough to stay put even in a stiff wind. Cones that do not have a round base plate must be aligned with at least one side parallel to the start/finish line.

6. The course must be set up accurately. The proper positions of the cones should be marked on the ground for a cone to be replaced quickly after it has been knocked over. An area of at least 1.5m in depth must be kept clear in front of the start line/behind the finish line, in which only equipment directly needed for timing is allowed to be located. With electronic timing, the light beams at the start and finish should be placed in such a way that the rider can cross the start and finish line at any reasonable location.

7. At least one practice course is required. If the practice course is not on a surface similar to the timed course, each rider should be allowed one practice run before their timed run. If they do not do both of their timed runs at the same time, another practice run should be allowed before the rider's second timed attempt.

In the linked PDF version hopefully all changes are highlighted: red and crossed out means this part is omitted, blue and italic is new.

Change Log:

Revision 7 changed by Jan Vocke (21 Sep 02:36): In paragraph 5 changed "The alignment of the cones is done in such a way that cones that do not have a round base plate are aligned with at least one side parallel to the start/finish line." into "Cones that do not have a round base plate must be aligned with at least one side parallel to the start/finish line."
Revision 6 changed by Jan Vocke (19 Sep 10:35): 1. Correctet typo in paragraph 3.
2. Changed in paragraph 5 "The alignment of the cones is done in such a way that the square, into which the base plate must fit, is aligned with two sides parallel to the start/finish line." into "The alignment of the cones is done in such a way that cones that do not have a round base plate are aligned with at least one side parallel to the start/finish line."
Revision 5 changed by Jan Vocke (11 Sep 07:53): 1. Changing back from "shall" to "must"
2. Specify what is meant by "The Starter gives the opening"
