Official Rules

IDSA Official Rules


1.   Race Information

1.1.               Seeded Numbers

  • The organizing committee may determine in advance of the event that a racer’s previous distance skateboarding achievements earn them a place toward the front line for the start of the race.  Documented proof of athleticism and a past history of competitive experience necessary.  The front line committee will be comprised of the race directors and/or industry media.  
  • Otherwise, you will receive a number in the order you check-in, and line up for the start line in that order.  
  • On race day you must wear your race number at all times. Your number will be worn on the front of your shirt/uniform, clearly visible, and it will be on a sticker placed on the back of your helmet.  Shirt/race top must be worn at all times.
  • Folding, cutting or intentional alteration of a bib number of any kind is prohibited. Some timing systems implant the timing strip into the bib, so folding the bib may compromise its functionality as well.
  • Providing or selling a race number to other athletes is strictly prohibited.

1.2.               Race Start

  • When starting the race, boards must be on the ground and 1 foot must be placed on the board. Any exceptions to this rule shall be clarified by the Event Director prior to starting the race.
  • With most timing chip systems, your time will not start until you pass the start line.

1.3.               Aid Stations

  • There should be multiple aid stations throughout the course, at minimum every 10 miles, and the at the Start/Finish area(s).
  • Water must be provided at each aid station along the course.  
  • Sponsor-provided energy / endurance supplements may be available at aid stations along the course.  
  • Racers are expected to understand their own race-day hydration and nutritional needs, and plan accordingly.   Racers should not rely on sponsor-provided supplements as their primary means of event day nutrition, since the product(s) provided may not be known until the day of the event.

1.4.               Drafting

  • Drafting is generally permitted.  However, any physical contact witnessed by a race official, e.g., pushing or pulling another racer, is not allowed and may be considered grounds for disqualification.
  • The Event Director may elect to disallow drafting, based on the race definition. Some races (such as 24-hour ultraskates) track records that must assume no assist or aid in the record attempt.

1.5.               Passing

  • On a straight course, racers must ride on the far right side of the course except when passing another skateboarder.   When passing, racers must pass on the left of the other skateboarders.  
  • On a counter-clockwise or clockwise circuit track (loop), the inside lane is considered the fast lane.   In general, racers must pass on the outside lane.   However, once the lead pack of racers begins to lap the slowest racers, the slower racers must remain aware of the lead pack’s approach from behind and yield the inside lane, allowing them to pass on the inside (fast) lane.
  • An inside dedicated “Leading Lane” may be explicitly marked on the course by the race director prior to the race start, to ensure the leading athletes may race unencumbered.  If so, the lane boundaries and rules will be explained by the race director prior to the event, and/or at the racer’s meeting prior to the event on race day.

1.6.               Racing and/or Behavioral Infractions

  • 1st offense racing / behavioral infractions will result in a warning.
  • 2nd offense racing / behavioral infractions will result in a disqualification.
  • Racing / behavioral infractions may be issued on or off the course.  
  • Racing / behavioral infractions may also be issued any time prior, during, or after the event.

1.7.               Weather Conditions

  • Plan and prepare accordingly. Get a sense for the climate of the event location and season ahead of time. Flatland distance racing will typically run rain or shine. Cancellation will only occur if the Event Director deems it unsafe to continue.
  • Should it be unsafe to continue a pace car will notify a true end point for racers.  Place will be determined upon completion of the cancellation finish line.


2.   Course Information

2.1.               The Start/Finish Line

  • The Start and Finish lines shall be clearly identified by the Event Organizers.  
  • The course shall be accurately measured with redundant systems well in advance of the event day.  Two or more of the following measurement systems are recommended:  track wheel, multiple GPS runs, accurately tuned bicycle odometer, surveyor-based city mile markers, GPS-map based websites.
  • The Event Organizer must communicate intended timing system details with the IDSA one month in advance of their event.  The timing system must be tested and approved prior to race day.
  • A camera positioned at the finish line will ensure that one winner is chosen, should the timing system not accurately provide the winner.
  • Any challenge of the course and rules must be submitted at the timer’s table within 15 minutes of finish time.
  • Medical personnel should be present at the start line and finish area.
  • Race organizers must define and communicate with the IDSA a complete, detailed set of age and/or gender classifications for race winnings, one month in advance of their event.   General guidelines are:  A large Open Division (either Mixed gender or Men’s/Women’s separated) that is eligible for the premium prize winnings, then smaller categories for winners in each age group, eligible for sponsor-donated schwag or smaller cash prize winnings, e.g., ages 13 and under, 14-18, 19-29, 30-39, 40-49, 50-59, and 60+.

2.2.               Course Elevation

  • Courses will be primarily flat to encourage consistent results globally, although there may be inclines and declines throughout.  
  • Elevation bias can be cancelled out by establishing the Start and Finish point at the same place.  

2.3.               Course Time Limit Policy

  • In order to comply with regulations, any roads formally sanctioned for race use will typically reopen in a graduated fashion.  Participants must be properly prepared and trained to complete the full course within the time frame the race director defines on the course description. However, the full course finish line will remain open for a period defined by the Event Director, depending on location.  The Event Director will communicate finish line limit time at the racers meeting on event day.
  • Participants must reach the half point mark within a time defined by the race director in order to be allowed to continue, at which point participants will be encouraged to stop their race early, before full completion. This is for personal safety of the participants.
  • Please note that after the official race finish time has elapsed, participant support (i.e., aid/water stations, volunteers, course marshals, clocks, etc.) is NOT guaranteed and you will be required to adhere to local pedestrian rules (move to curbsides, break down lanes, sidewalks, etc.)
  • Medals and official finish times will be given to all finishers who complete the race within the official race finish time.
  • The cut-off times are based on chip time, not gun time, in consideration of the additional time it takes the start corrals to clear through the start line.

2.4.               Course Signage

  • Course markers, directional arrows, and other signage should be positioned throughout the course.

2.5.               Checkpoints

  • Timing system mats / strips / etc., should be placed at the start and finish lines. There should also be multiple checkpoints throughout the course to ensure no cheating.

2.6.               Ambulance/Fire Rescue

  • An ambulance and fire rescue unit should also be prepared and roaming through the course to ensure safety.

2.7.               Toilets

  • Portable toilet units or immediate access to existing toilets should be placed for convenience throughout the course, preferably near each aid station.

2.8.               Video Cameras/Photos

  • Video cameras and photo cameras should be located at the finish line to ensure that any finish disputes can be resolved.
