Terms and conditions
Last updated: 17 August 2026
These terms apply to the personal running, HYROX and general fitness coaching provided by Train with Dario. They are written in normal language so you know what to expect before you start.
Your personal offer sets out exactly what you receive, what it costs and how long the coaching lasts. These general terms supplement those arrangements; mandatory consumer rights always take priority.
1. Who we are and what these words mean
Train with Dario is the coaching service of Dario Mulder, based in the Netherlands. Full business and contact details appear in the personal offer and on the invoice. You can also reach Dario through the contact form on this site.
‘You’ or ‘participant’ means the person receiving coaching. ‘Coaching’ means the agreed support, such as a personal training plan, reviews, feedback and any live sessions. The ‘offer’ is the quotation or written confirmation describing your package.
2. When these terms apply
These terms apply to every offer and agreement between you and Train with Dario. You receive them before or when the agreement is made, in a form you can save. If your offer expressly says something different, that specific arrangement takes priority. Mandatory legal rights always remain in force.
3. Offer and agreement
Submitting a coaching application through the website is non-binding and does not create an agreement. The agreement starts only when you accept the personal offer in writing or electronically. The offer states at least the coaching scope, price including VAT, duration, start date, payment arrangements and any agreed frequency of contact or sessions.
The offer remains valid for the period stated in it. If no period is stated, it is valid for 21 days. The agreement is personal and cannot be transferred without prior permission.
4. What to expect from coaching
Dario provides the coaching with reasonable care and skill. Its content may be adjusted during the programme to reflect your progress, recovery, availability and feedback, while preserving the agreed objective and core package. Coaching is a best-efforts service: no specific result, race time, weight change or other outcome can be guaranteed.
You provide the information and feedback reasonably needed for effective coaching and let Dario know when your circumstances change. Missing or late information may affect planning and results.
5. Cooling-off period for distance contracts
If you are a consumer and enter into the agreement online, by phone or otherwise at a distance, you generally have a 14-day cooling-off period from the day the agreement is concluded. During that period, you may withdraw without giving a reason by sending Dario a clear statement.
If you want coaching to begin during the cooling-off period, we ask for your express permission first. If you then withdraw, you pay only a proportionate amount for the part supplied at your request. The right of withdrawal ends after full performance within the cooling-off period only if you expressly agreed in advance and acknowledged that the right would end.
6. Duration, renewal and cancellation
The duration is set out in the offer. A fixed-term programme ends on the agreed end date unless a continuation was clearly agreed in advance. Paying an invoice does not by itself count as accepting a new agreement or renewal.
You can cancel a monthly programme, or one that continues indefinitely after a fixed term, in the same way you entered into it and with no more than one month’s notice. During an agreed fixed term, you may end early only if the offer allows it, Train with Dario fails to perform the agreement, or the law gives you that right. In the event of long-term illness or another serious change in circumstances, we will gladly try to find a reasonable solution together.
7. Cancelling appointments
You can move or cancel an agreed live session or call free of charge up to 24 hours beforehand. A later cancellation or no-show may count as a used session, unless that would be unreasonable in the circumstances. If Dario cancels, the appointment will be rescheduled or you will receive an appropriate credit or refund for the undelivered part.
8. Prices and price changes
Consumer prices include VAT unless clearly stated otherwise. The agreed price for a fixed term does not change, except where a legal measure such as a VAT change makes this necessary.
For an indefinite agreement, a price may change only if this possibility was clearly agreed beforehand. You will receive at least 30 days’ advance notice of the new price and effective date. If the change is to your disadvantage, you may cancel free of charge before it takes effect, except to the extent that it results solely from a legal measure.
9. Payment
You pay within the period and by the method stated in the offer or invoice. If payment is overdue, Train with Dario may pause coaching after sending a reminder; payment remains due for services correctly supplied.
If you are a consumer, you first receive a legally compliant reminder and 14 days to pay before collection costs are charged. After that, only statutory interest and collection costs permitted by law may be charged.
10. Health and safety
Coaching is not medical care, diagnosis, treatment or nutrition advice. You are responsible for deciding whether training is medically appropriate for you. If you have doubts, symptoms, injuries, are pregnant, use medication or have a relevant condition, consult a qualified doctor or other healthcare professional before or during the programme.
Disclose relevant limitations honestly and promptly, follow safety instructions and stop immediately if you experience pain, dizziness, shortness of breath or other concerning signs. In an emergency, contact the emergency services rather than the coach.
11. Your responsibility
You remain responsible for carrying out training, using suitable equipment, choosing a safe environment and following the rules of gyms, events and public locations. Do not make risky changes to a session on your own, and raise any doubt or unexpected training load as soon as possible.
12. Training plans and intellectual property
Training plans, schedules and other coaching materials are personal to you. You may not sell, publish, copy them for others or use them commercially without prior permission. Your own training data and personal information naturally remain yours.
13. Liability
Train with Dario is liable for loss to the extent that it is the direct result of an attributable failure or unlawful act. Nothing in these terms excludes liability that cannot legally be excluded, including loss caused by intent or deliberate recklessness.
To the extent permitted by law, Train with Dario is not liable for loss caused by inaccurate or incomplete information, failure to disclose relevant health information, ignoring safety instructions or performing training differently from the advice given. You remain responsible for personal belongings during training and events.
14. Force majeure and coach unavailability
In a force majeure event — a situation beyond reasonable control that temporarily prevents performance — obligations may be suspended for as long as it lasts. We will discuss rescheduling or a suitable alternative. If performance becomes permanently impossible, either party may end the undelivered part and any advance payment for that part will be refunded.
15. Complaints
If you are unhappy, please explain the issue clearly and as soon as possible using the usual contact details. Dario will respond within 14 days. If more time is needed, you will be told within that period when to expect a substantive response. This does not limit any statutory right.
16. Personal data
Personal data is processed to provide coaching. The privacy policy explains what is used, why it is needed and what rights you have.
17. Changes to these terms
New terms apply to new agreements. Terms for an ongoing agreement can change only where that was agreed in advance and the change is reasonable. You receive the new text before it takes effect. If a change is materially to your disadvantage, you may end the agreement before it takes effect unless the change is legally required.
18. Governing law and disputes
Dutch law applies to the agreement. If you live as a consumer in another country, you retain the mandatory protections provided by the law of your country of residence. We first try to resolve any dispute together. If that does not work, it may be brought before the court that has jurisdiction under the law.
