The start will be personalised by the Organiser for each team according to the pace of the participants. Each team must be at the start at the time indicated on the invitation.


The Organiser reserves the right to modify the timetable and/or the course up to the day of the race.

Article 3 – Registration

Run Mate by Core Lean Lac Léman is open to all participants born before 31 December 2004.

You must be 18 years old in the year of the race to participate.

Anyone entering the race must be well trained and in good health. It is therefore strongly recommended that all participants undergo a medical check-up and seek medical advice before taking part.

Anyone wishing to participate in the race must be registered on the event’s registration platform. If a runner is not registered, he or she will not be covered by the organisation in case of an accident.

Participants are registered in order of receipt of payment. However, a maximum number of runners may be set by the organisation. Once this maximum number is reached, registrations will no longer be considered.

In the event that a team wishes to be accompanied by a third party (e.g. a driver), this person is not considered a participant under these rules. The Captain nevertheless undertakes to declare the presence of any person accompanying the team for security purposes. Registrations can be made on the internet at:

Participants can register for the different formulas via the dedicated platform until the maximum number of bibs is reached.

Formulas proposed:

· TEAM: from 6 to 9 people

· ULTRA : from 2 to 5 people

Students can benefit from a preferential rate of 10% on the registration fee. Please note that each participant wishing to benefit from the discount must be able to present proof of schooling valid until September 2023 . Otherwise, the difference in price will have to be paid in order to validate the registration.

Due to the context, additional elements may be requested from each participant (PCR test, health pass, etc). Participants may also be asked to respect any sanitary measures (wearing a mask, respecting safety distances, etc.).


If the number of participants has to be reduced, the rule applied on the order of priority according to the date of registration.

Article 4 – Engagement

All registrations are firm and final, and no refunds will be made in the event of a registration error, medical reasons, unavailability, etc.

For those participants who wish to do so, a “cancellation” insurance is offered at the time of registration. This insurance cannot be taken out after the event.

No transfer of registration is authorised for any reason whatsoever.


Any person who transfers his or her bib to a third party without informing the organisation will be held responsible in the event of an accident occurring or caused by the third party during the event. The organiser declines all responsibility in the event of an accident in this type of situation.

Article 5 – Bib collection

The bibs will be collected on :

· Saturday 23 September 2023 at the Village (start) in Montreux.

Bibs will only be given out on presentation of an identity document and the invitation e-mail sent by the organisation. This invitation e-mail will be sent, a few days before the race, exclusively by e-mail, to the e-mail address given by the Captain at the time of registration. The compulsory equipment will also be checked at the time of the bib collection. The list of compulsory equipment can be found on the event website:


The bib must be fully legible and worn in front by the runner doing the relay throughout the course.

Article 6 – Race time

Your official race time will be the time between your crossing the start line and your crossing the finish line. It is reminded that controls will be carried out during the event, at each relay point, in order to ensure perfect conditions of regularity of the race. It is possible that some sections will be neutralised, i.e. without time - due to bad weather that would make some sections impassable for example.

Your race time will be measured by a GPS beacon provided by the organisation before the start of the team. The runner will have to give the beacon to the next runner, the beacon serving as a relay baton.

The maximum overall time to complete the course is 28 hours.

In advance of the opening time of a relay

Runners ahead of the estimated race time of the first team will be stopped for an indefinite time. This waiting time will be deducted from their final time.

Late on the estimated race time

Conversely, runners who are out of time limit will be obliged to advance by as much distance as necessary as indicated by the organisation. This will allow them to finish the race within the time limit. However, this will result in a non-classification for “out-of-time limit”.


In case of not following the marked route, and depending on the diversions taken, the teams will be given a time penalty corresponding to 5min/km.

Article 7 - Timing

The timing will be done by a timekeeper using an electronic system.


Any complaint may be made up to 3 days after the date of the event, after which time no changes will be made.

Article 8 – Abandon

With the exception of an injury requiring rapid medical intervention, if a team wishes to abandon, it must indicate this in a relay zone to any member of the organisation and call the organisation’s emergency number given in the Roadbook.

Article 9 – Rules & Safety
