There will be no ceremony with less than 7 people in an Age Group. Of course, every participant is in the results list that is also published online on the DTS website.


The Dutch Triathlon Series (DTS) work with its own official team who ensure that the race runs according to the rules. Participants must adhere to our regulations. DTS officials have the power to disqualify any competitor who fails to comply with the rules outlined below.


  • Participants must at all times follow the directions of traffic controllers and police officers. Earphones are not allowed during the entire race!
  • Always comply with the applicable traffic rules (unless otherwise indicated by traffic controllers and police officers) and understand that the course is accessible to the public and traffic. The areas closed to traffic can also be used during the event by emergency services and vehicles connected to the event. Therefore, keep to the traffic rules at all times. Driving is on the right.
  • The DTS medical team is entitled to remove athletes from the competition if they consider it necessary.
  • We ask all participants to behave in a good and sporty manner, and to treat other participants, event staff and volunteers with proper and respectful behavior.
  • Disposal of waste is only allowed in waste zones. The waste zones are located around the care stations and are clearly indicated. If a competitor throws waste outside this zone, he or she can be disqualified.
  • If a participant chooses to leave the competition, he/she must inform the officials as soon as possible. If this is not met and a search and rescue is initiated, the associated costs will be claimed from the relevant participant if he/she is at home or in a hotel/accommodation at that time.
  • The DTS organization reserves the right to change regulations, courses and locations at any time. However, the participants must be informed of this before the start of the competition, unless the change directly concerns the safety of the athletes.
  • Headphones or earplugs are not permitted for the swimming, cycling and walking part.
  • Participants (m/f) in the DTS are not allowed to go bare-chested on the cycling and running course.
  • Each participant must familiarize himself with the course, it is his/her own responsibility to follow the correct route (apart from deviating instructions from traffic controllers, police officers and organization).
    • DTS reserves the right – when weather conditions so require – to give the competition Duathlon status, for the safety of the participant. There will be no (partial) refund of registration fees. If the weather conditions are so bad that the safety of the participants in a duathlon cannot be guaranteed, the DTS organization can choose to cancel the event in its entirety. In case of cancellation, the registration fee will not be returned.
  • The issued start numbers must be visible throughout the cycling and running segment.



  • All participants receive a swimcap. This must be worn at all times when the participant is in the water.
  • Any adjustments to the swimming part will be communicated during the participant’s briefing based on the then prevailing weather conditions, water temperature and any changes in swimming distance.
  • Fins, paddles, snorkels and flotation devices are prohibited.
  • Swimming or diving goggles may be worn.
  • If a participant receives help during the swimming part (for example from canoeists or rescue brigade) this can lead to disqualification.
  • The organization of the event has the right to move the swimming course, to shorten it or to cancel the swimming part if the weather conditions, water temperature or general water condition require this.



  • Drafting is not allowed. The “draft zone” is 12 meter and 3 meters wide (one and a half meters on either side from the front wheel) between the front point of the rider in front and the rider behind it. An overtaking action (complete passing of the draft zone) must be completed within 20 seconds. Subsequently, the overtaken athlete should have disappeared from the drafting zone of the former athlete within 5 seconds.
  • The start numbers may not be reduced or modified in any other way. The number should be worn on the back with bicycles.
  • Wearing a safe bicycle helmet is mandatory.
  • The bicycle helmet must be attached with the chin strap before the bicycle is removed from the rack. Subsequently, the helmet may not be removed again until the bicycle is in the rack after the bicycle part.
  • Individual guidance is not allowed. The cycle track is closed to support vehicles. A participant may not seek or accept help from spectators, escorts or third parties, with the exception of official technical support from the organization or within the coach posts.
  • A participant is responsible for the condition and any repair of the bicycle. The bicycle must be well maintained and in a ready-to-drive condition before the start of the event. The competitor must be able and prepared to be able to carry out any necessary repairs himself, accepting help with this may lead to disqualification. This excludes the use of spare wheels or spare bicycles. When checking in the bicycle, a basic technical check is done, whereby only the bicycles that meet the requirements are admitted to the transition zone. The helmet must be checked in at the same time as the bicycle and may then only leave the transition zone during and after the race.
  • Cyclists are expected to follow the instructions and directions of all race officials and authorities. Participants are allowed to walk by hand if necessary.
  • Participants must keep to the right as much as possible on the course. Overtaking must take place on the left.
  • Penalties for drafting, dangerous riding and unsportsmanlike conduct will be determined by the jury and may lead to disqualification.
  • The organization of the event has the right to move or shorten the cycle route if the weather conditions or route conditions so require.




  • The start numbers may not be reduced or modified in any other way. The number should be worn on the front of the body while walking.
  • Participants must walk as much as possible to the right so that passing to the left remains possible.
  • Individual guidance on the course (in the form of non-participating runners, cyclists or other vehicles) is not allowed. Taking food or other attributes is not allowed outside the coach post and may lead to disqualification.
  • The organization of the event has the right to move or shorten the running course if the weather conditions or course conditions so require.
