distance:
• Sprint Distance: 14 years;
• Olympic Distance and 1/3 Distance: 16 years;
• Middle Distance: 18 years.
2.2 Registration
The Participant may only take part if the registration form has been completed fully and truthfully, the amount due has
been paid in full, the Participant has accepted these general terms and conditions, and any additional conditions for
the relevant Event or discipline have been met.
2.3 Responsibility for registration details
The Participant is responsible for correctly entering and checking personal details, the selected Event, distance,
starting category, additional products and other registration details.
2.4 Changes.
Certain details may be changed by the Participant through their personal online registration platform within the period
specified by DTS. DTS may charge administration or amendment fees for certain changes.
2.5 DTS FLEX 80 replaces the transfer-to-another-event arrangement
From the 2027 season, DTS introduces DTS FLEX 80 as a new flexible cancellation option. This arrangement
replaces the option available in previous seasons to move a registration to another DTS Event for a fee.
By purchasing DTS FLEX 80 at the time of the original registration, a Participant can choose additional flexibility.
If DTS FLEX 80 has been purchased, the Participant may cancel without giving a reason up to six calendar days before race
day and will then receive a refund of 80% of the Entry Fee paid, in accordance with Article 3.
With the introduction of DTS FLEX 80, from the 2027 season it is no longer possible to move, convert or transfer an
existing registration to another DTS Event or a subsequent season at the Participant's request. Registrations will no
longer be converted into vouchers for future DTS Events.
2.6 Transfer to another person
A Participant may transfer their registration to another person up to 14 calendar days before the Event, provided that
person is not already registered for the same discipline of that Event and meets all participation requirements.
A name change/transfer may only be carried out by the registered Participant themselves through their personal
online registration platform. DTS does not process requests for name changes sent by email or social media and
does not respond to them.
It’s not possible to transfer/sell a Relay ticket to another person.
The following administration fees apply to a transfer to another person and must be paid online immediately after the
transaction:
• Sprint: €25
• Olympic Distance: €35
• Middle Distance: €45
Once the deadline of 14 calendar days before the Event has passed, transfers are no longer possible.
2.7 Effect of a transfer on DTS FLEX 80
DTS FLEX 80 is a personal cancellation option purchased by the original Participant during the original registration.
When a race entry is transferred to another person, DTS FLEX 80 is not transferred with it. The DTS FLEX 80
surcharge paid is not refunded. The new Participant cannot add DTS FLEX 80 afterwards.
ARTICLE 3 – CANCELLATION AND DTS FLEX 80
3.1 General rule on cancellation
Registration for a DTS Event is final. If a Participant cancels their participation or cannot or does not wish to take part
for any reason, there is in principle no entitlement to a refund of the Entry Fee. The sole exception applies where the
Participant purchased DTS FLEX 80 during the original registration and meets all the conditions of this Article. A
registration cannot be moved to another DTS race or converted into a voucher or credit.
3.2 DTS FLEX 80
DTS FLEX 80 is an optional flexible cancellation arrangement under which a Participant may cancel participation
without giving a reason up to six calendar days before the Event and then receive a refund of 80% of the Entry Fee
paid. DTS FLEX 80 is not insurance. In the event of a valid cancellation, the Participant does not have to provide a
medical certificate, evidence or any other reason for cancelling.
3.3 DTS FLEX 80 fees.
The following fixed surcharges apply for the 2027 season:
• Sprint: €15
• Sprint Relay: €20
• Olympic Distance: €20
• Olympic Distance Relay: €25
• Middle Distance: €35
• Middle Distance Relay: €40
Dutch Triathlon Series • Amsterdam Sport Events B.V. • 2027The amount of the DTS FLEX 80 surcharge does not depend on when registration takes place or on the Entry Fee
applicable at that time.
3.4 Purchase of DTS FLEX 80
DTS FLEX 80 may only be purchased during the original registration process for the relevant Event.
During registration, the Participant makes a deliberate choice whether or not to purchase DTS FLEX 80. DTS FLEX
80 cannot be added after the original registration has been completed. DTS FLEX 80 is linked to one specific
Participant, registration and race.
3.5 Refund withDTS FLEX 80
If a Participant cancels correctly and on time with a valid DTS FLEX 80 option, the Participant will
receive a refund within 14 days of 80% of the Entry Fee actually paid for the race entry. The DTS FLEX 80 surcharge
itself is not refunded. Transaction fees, booking fees, service fees, administration fees and purchased items are
likewise not refunded unless expressly stated otherwise in these terms and conditions. An exception applies to a
wetsuit rented through DTS registration: in the event of a valid and timely cancellation with DTS FLEX 80, the rental
fee of €55 will be refunded in full (100%).
3.6 Refund example
A Participant registers for an Olympic Distance and pays €100 for the race entry, €20 for DTS FLEX 80 and €55 for a
rented wetsuit. In the event of a valid, timely cancellation, €80 of the Entry Fee plus €55 for wetsuit rental will be
refunded, a total of €135. The €20 DTS FLEX 80 surcharge will not be refunded.
3.7 DTS FLEX 80 deadline
A Participant with DTS FLEX 80 may cancel up to 11:59 p.m. Netherlands time six calendar days before race day.
For a race on Saturday, the deadline is the preceding Sunday at 11:59 p.m.; for a race on Sunday, it is the preceding
Monday at 11:59 p.m. After this deadline, the entitlement to a refund through DTS FLEX 80 expires entirely,
regardless of the reason, including illness, injury, pregnancy, family circumstances, work, travel or transport
problems.
3.8 Method and timing of cancellation
Cancellation with DTS FLEX 80 is only possible via the cancellation button in the Participant's own dashboard. To
access it, open the registration confirmation email and click the blue “My dashboard” button. Once in the personal
online registration platform, the Participant can click the “Cancel with FLEX 80” button. After processing, the
applicable refund amount will be returned through the payment method used by DTS. Processing time may depend
on the registration provider, payment provider and/or bank, but the refund will be arranged within a maximum of 14
days.
3.9 Cancellation is final
Once a cancellation with DTS FLEX 80 has been processed, the relevant race entry becomes invalid. The
registration cannot be reactivated or moved. If the Participant subsequently wishes to take part, they must purchase
a new race entry, subject to availability and at the rate then applicable.
3.10 No DTS FLEX 80?
If a Participant did not purchase DTS FLEX 80 during the original registration, voluntary cancellation does not entitle
them to a refund of the Entry Fee, regardless of the reason. A registration without DTS FLEX 80 likewise cannot be
moved or converted into a voucher or credit.
3.11 Purchased items and shipping after cancellation.
Purchased items are not covered by the DTS FLEX 80 refund arrangement. This includes finisher shirts, Lock
Laces/shoelaces, race number belts and other items purchased during registration.
Finisher shirts are produced specifically for the relevant Event. An ordered and paid-for finisher shirt therefore cannot
be cancelled and its purchase price will not be refunded.
A Participant who cancels and has ordered a finisher shirt may have the shirt sent by post after the Event. Shipping
and administration fees of €15 apply. If the same Participant has also purchased Lock Laces/shoelaces and/or a race
number belt, these will be included in the same shipment at no additional shipping charge.
If a Participant who has cancelled has not ordered a finisher shirt but has purchased Lock Laces/shoelaces, a race
number belt and/or other suitable purchased items, these may be sent by post upon request. Shipping and
administration fees of €10 apply.
The Participant must notify DTS that they wish to receive the items by post and must pay the applicable shipping and
administration fees. Requests may only be submitted via info@dtseries.nl.
3.12 Cancellation or modification of the Event by DTS
DTS FLEX 80 applies exclusively to voluntary cancellation initiated by the Participant. DTS FLEX 80 does not
determine the rights that apply when an Event is cancelled, rescheduled or modified by the Organiser. In such
situations, the other provisions of these terms and conditions and applicable mandatory law apply. DTS FLEX 80
does not provide any additional entitlement to compensation.
ARTICLE 4 – MODIFICATIONS, FORCE MAJEURE AND SAFETY
4.1 The Organiser may decide to modify an Event or any part of it due to exceptional circumstances, force majeure,
safety risks, weather conditions, water quality, blue-green algae, high waves, extreme temperatures or other
circumstances.
4.2 For safety reasons, a triathlon may, for example, be changed to a duathlon/Run-Bike-Run. Swimming, cycling or
running disciplines may also be shortened, modified, relocated or cancelled where the Organiser considers this
necessary.
4.3 Such a change to the race format does not automatically entitle the Participant to a full or partial refund of the
Entry Fee.
4.4 If an Event has to be cancelled in its entirety, postponed or relocated, DTS will inform Participants as soon as
possible about the consequences and any applicable arrangement, taking account of applicable mandatory law.
4.5 DTS FLEX 80 is not event cancellation insurance and does not affect the Organiser's powers described in this
Article.
ARTICLE 5 – TIMING CHIP AND RENTAL EQUIPMENT
5.1 ProChip
DTS uses the MYLAPS ProChip system. Participants cannot use their own yellow or green ChampionChip. ProChip
rental is included in the registration fee. The Participant must return the chip after the race exclusively at Bike Check-
out. If the chip is not returned or is lost, replacement costs of €25 may be charged.
5.2 Rented wetsuits
Participants may rent a wetsuit during registration. For the 2027 season, the rental price is €55.
From the 2027 season, rented wetsuits will not be sent to Participants by post in advance. Participants must collect
their rented wetsuit themselves from the Dare2Tri and/or De Boer Wetsuits stand at the Event venue.
As partners, Dare2Tri & De Boer Wetsuits will have a stand at all DTS Events from the 2027 season and will offer a
free wetsuit test day on the day before the race. The Participant may collect the rented wetsuit either on race day or
the day before. During the wetsuit test day, the Participant may try on the wetsuit and, where conditions and the
programme permit, test it in the water. Exact opening hours will be communicated by DTS in advance.
After the race, the rented wetsuit must be returned to the Dare2Tri and/or De Boer Wetsuits stand. The Participant is
responsible for returning it correctly and on time.
In the event of a valid cancellation with DTS FLEX 80 within the deadline specified in Article 3, the rental fee of €55
will be refunded in full.
ARTICLE 6 – PRIZES AND AGE GROUPS
Each finisher will receive a finisher medal, where applicable to the relevant Event. DTS will provide awards for
Overall Women, Overall Men, Relay Teams and various Age Groups. These will be presented during the podium
ceremonies.
DTS uses the following Age Groups:
• 14–29
• 30–39
• 40–49
• 50–59
• 60+
For each individual Age Group, at least ten Participants must be registered in the relevant category to qualify for a
podium ceremony with awards. If fewer than ten Participants are registered, DTS may decide not to present separate
podium prizes for that Age Group. First-, second- and third-place prizes are presented only during the podium
ceremony and will not be sent afterwards. Official results will be published online on the same day.
ARTICLE 7 – LIABILITY AND PARTICIPATION AT OWN RISK
7.1 Participation in a DTS Event is at the Participant's own risk. Triathlon and its individual swimming, cycling and
running disciplines involve physical exertion and inherent risks.
7.2 To the extent permitted by law, the Organiser is not liable for damage or loss suffered by the Participant because
of participation in the Event, including loss, theft or damage to personal property.
7.3 No limitation or exclusion of liability applies to the extent that liability cannot be excluded or limited under
mandatory law.

Event.

than 14 days after the Event.

material for reporting, communications and promotion of DTS and its Events, insofar as permitted under applicable
law.

Participants must be registered within the relevant category, unless DTS determines otherwise for a specific Event.
ARTICLE 11 – RACE RULES
DTS works with its own team of race officials/judges, who oversee a safe and fair competition. Every Participant must
comply with the DTS race rules and the instructions of the organisation, judges, traffic marshals, police, medical

during the race, such as a puncture, must therefore be resolved by the Participant themselves. No outside assistance
may be accepted during the race, and the organisation does not provide a sweep vehicle to collect stranded
