FAQ
Registrations
What is the registration deadline? Until when can I register on site?
The deadline for online registration is Thursday August 6, 2026 at 11:59 pm (excluding National League and Youth League).
Registrations made after July 6, 2026 will be subject to a surcharge of CHF 15 (except for the Tri Kids).
On-site registration will be possible up to 45 minutes before the start of the relevant category (subject to availability).
Can I pay for my registration with a foreign bank account?
It is possible to pay for your registration with a foreign bank account. Our partner Datasport offers a wide range of payment options when you register.
Where can I check that my registration has been taken into account?
Registration can be viewed on the bibs page of our website by clicking on the “Start list” button. Depending on the method of payment, there may be a delay of a few days before the registration is visible (between 3 and 5 days).
When can I get a refund of my registration fee?
If no cancellation insurance has been taken out when registering online, no refund will be made by the organizer (even on presentation of a medical certificate).
Should the competitor not possess the required equipment (wetsuit if required, hard hat, etc.) or in the event of cancellation of the event due to weather conditions, force majeure, external events or extraordinary circumstances, no refund will be made in principle.
Is it possible to change my registration (participation in a different race, change of person, etc.)?
Any change to a registration will be billed to the participant at CHF 15. This amount must be paid in advance by Twint or in cash when picking up the race number (the race number will not be given to the participant without payment).
Can I register for National and Youth League races with a foreign licence?
A competition license from Swiss Triathlon (StartPass) or an ITU/ETU-affiliated foreign federation is compulsory for the following individual races affiliated to a national series: Youth League 14-15 and National League. You can register here.
Bibs and licenses
When can I collect my race number?
Bib numbers can be collected on site on presentation of your registration confirmation at the following times:
- Friday, August 7, 2025 from 5 p.m. to 8 p.m.
- Saturday, August 8, 2026 from 6:30 a.m. to 45 minutes before the start of the race
- Sunday August 9, 2026 from 6:30 a.m. to 45 minutes before the start of the race.
Is it possible to get the number back for another person?
Yes, it’s possible (except for NL and YL races). All you need to do is present your registration confirmation e-mail when you pick up your race number.
For which races do I need a medical certificate?
No medical certificate is required, even if you don’t have a license. However, you must be covered by accident or civil liability insurance.
Which categories require a license and when do I need to buy one?
Participants in the Nyon Triathlon must be in possession of a license (Swiss or foreign) in order to take part in the events. A daily license can be purchased at the time of registration on the Datasport platform, depending on the type of race:
- StartPASS: Olympic Distance (individual race), National League and Youth League
- EasyPASS: Duathlon, short distance and relays
- FunPASS: Discovery Triathlon and Aquathlon
Holders of a Swiss annual license (StartPASS) or a foreign triathlon license do not need to purchase a daily license.
Do I have to be a member of Swiss Triathlon to get a licence?
No, but the acquisition of a daily license at registration is equivalent to authorization to participate in an official Swiss Triathlon competition. All foreign licenses are accepted, without the need to purchase a Swiss Triathlon daily license.
Do I need a medical certificate to obtain a license?
No medical certificate is required, nor even proof of membership of a sports club.
Does a foreign license (e.g. French) exempt me from buying a Swiss license?
A foreign license effectively dispenses with the need to purchase a Swiss license to take part in Triathlon Series events.
I have a foreign licence, can I join the National and Youth League races?
A competition license from Swiss Triathlon (StartPass) or an ITU/ETU-affiliated foreign federation is compulsory for the following individual races affiliated to a national series: Youth League 14-15 and National League. You can register here.
Races
Are there time limits for each discipline?
Yes, time limits are defined for the Short Distance and Olympic Distance categories (seerulespage). You are free to finish your race, but you do so on your own responsibility, on a course open to traffic and without the presence of volunteers or medical equipment; total timekeeping cannot be guaranteed.
When are neoprene wetsuits permitted/forbidden?
Wetsuits are forbidden if the water temperature is 22°C or higher, and compulsory if the water temperature is 15.9°C or lower. The decision is taken each race day by the referees and communicated by the speakers 1 hour before the start.
Are neoprene shorts and/or leggings allowed?
If neoprene wetsuits are not permitted – i.e. when the water temperature is 22°C or higher – neoprene shorts and leggings are also forbidden.
Do I need three participants to take part in the relay?
As a general rule, and to be on an equal footing with the other teams, it would be best if there were three of you. If you can’t find anyone, we can exceptionally accept only two of you in a relay. Note that running two of the three disciplines is only a problem if you swim, pass the baton to a cyclist and then the cyclist passes the baton to you to run.
What to do if you’re looking for someone to complete a relay team?
If you’re looking for a relay operator, we advise you to share the information on social networks.
Is it possible to take part with an electric bike?
The use of assisted and electric bicycles is prohibited.
Is it possible to take part with a mountain bike?
Mountain bikes can be used as long as they comply with Swiss Triathlon rules: https: //www.trinyon.ch/reglement/
Is it possible to take part with headphones for the music?
For safety reasons and in accordance with Swiss Triathlon regulations, it is not permitted to use headphones when cycling or running.
What does rolling start mean?
For rolling starts, athletes will start in groups of 5 every 15 seconds.
Miscellaneous
Do I need special insurance, or is liability insurance enough?
In Switzerland, everyone is covered by their accident insurance or, where applicable, their health insurance. For foreigners, accident insurance cover is compulsory to take part in the Nyon Triathlon.
Where and how do I return my Datasport chip?
Any unreturned chip will be invoiced to the athlete at CHF 50. The chip must be sent directly to Datasport, in a padded envelope for protection, to the following address:
