Frequently Asked Questions

Have a look at our FAQ page as we may have answers to your question already.

Run Mate by Core-Lean Lac Léman is a relay race (2 to 9 runners) around Lake Geneva over 2 days and one night. Run Mate by Core-Lean may be a race, but first and foremost, it is a shared adventure.

Put all your Mates in a van (or in two cars if you don’t have a van) and get them to run about 215 km around the biggest lake in Switzerland and France! There will be approximately 28 relay legs in all, from 3 to 13km in length, which makes around 25 km per Mate (if you are more than 8) with varying levels of difficulty according to how your team is organised.

Only one runner at a time is allowed on the course, while the other Mates can rest, cheer on their runner or complete the challenges!

While the runner is on the course, the van has to drive to the next relay point to wait for him or her. The Mates only have telephone contact with the runner to encourage or help if he or she goes the wrong way. They are not allowed to follow the runner on the course.

FREEDOM is the key word here. You can plan the legs as you wish.

One runner might only run one relay leg during the entire race. But one runner could also run two, three or four legs in a row if he or she feel like it. There is no minimum or maximum number of relay legs to do per runner.

Yes, everything will be communicated to you in the Roadbook closer to the event. 

The organisers’ main role during the event is to ensure that the Mates stay safely on the signed course. If they do get into trouble the organisers will contact them by phone.

They will be in phone contact with the organisers and with their runner. Their role is to pass on important information.

If your runner takes a wrong turn, the organisers will contact you and you in turn will have to contact your Mate in order to help him or her to get back on track.

No, no roads will be closed for the race. You will run on tracks, paths and pavements with a minimum number of roads to cross. Where there are roads to cross this will mainly be on pedestrian crossings. On the few occasions where this is not the case, there will be marshals present (from the organising team) to help you cross.

70% of the course will be on the road, 30% trails.

YES Absolutely! Since it’s up to each team to decide how to run the race you can run just one leg of 3km or you can run a lot more if you are up to it. If you spread the legs in a roughly equal way between each runner, you will each run a half-marathon (if you are more than 8) but over 24 hours and with a nice long rest in between each section!

Most “normal” relay points will have toilets and a water supply to refuel your bottles. A precise map is available in the Roadbook.

On the super relay points a small solid supply (fruit, cereal bar) will be provided in addition to water and isotonic drink.

We will provide you with a relay bracelet with the team GPS markers in it and a bib per team member. When passing the relay, you only have to send the relay bracelet.

No dedicated space will be provided by the organization. We encourage you to organize your vehicle so that your nap is comfortable. The edge of the lake and the relay points will also be places for napping.

We set time barriers corresponding to the theoretical run times of the last rider. If a team exceeds the time limit, the organisation reserves the right to ask an off-times team to “skip” one or more relays (i.e. not to run it and to go with your vehicle to the relay point indicated by the organisation). This will automatically result in the team not being classified (DNF) but the team will still be allowed to finish the race.

If you are too much in advance, the organisers reserve the right to stop a team at a relay point for an undetermined period of time in order to avoid congestion on the course and to respect the current sanitary measures. Any time stopped at a relay point will be deducted from your overall time.

Yes, you will simply need to retrieve the GPS beacon and pick up where your mate left off.

  • The runner calls his team who will come and pick him or her up
  • As each team is free to plan the relay stages as they see fit, any other runner from the team can replace an injured runner, while the latter can get back in the vehicle
  • The replacement runner must continue the race at the place where the other stopped and take the GPS beacon of the former runner.
  • If there is a vital emergency, call one of the emergency numbers according to which country you are in (Vital Emergency in Switzerland: 144 / Vital Emergency in France: 15)
  • If there is no urgency you can consult our medical team at each Super Relay points.

An alarm system will allow the organisers to be the first to know if a runner deviates significantly from the course. The organization will contact the team captain to explain him/her the situation. The captain will be in charge of contacting his/her mate to warn him/her.

If you haven’t been contacted by the organisation, you can call them at the Race control number (available in the Roadbook).

If you can no longer see the signs on a certain section, check your position on the route using the application.

Each Mate must respect the highway code and the race environment. Please refer to our safety guide to ensure that runners stay safe at all times.

The course is not 100% signed, but the main junctions, changes in direction and other less obvious routes will be marked.

The markers will be visible by night. An example can be found in the safety guide.

High visibility vests are mandatory for the night portion of the race. The organisers reserve the right to disqualify any teams behaving in an unsafe manner.

There are several ways to find your way around the course:

- Use the route planner. The application is available for free on the App Store and Play Store. The route planner for runner and vehicle will be available closer to the event.

- Get your bearings with Google Maps.

- Get your bearings with the live course on our website the weekend of the event.

- The map of the route is available in the Roadbook.

- Markers are set up along the route with fluorescent pink signs at night. The arrows indicate the direction to follow. Cross-shaped signs will tell you if you are going in the wrong direction.

No, you must run obligatorily with the GPS beacon AND the mobile phone for safety reasons. We strongly recommend that you download the application.

Yes, you and your friends will be able to follow your Mate live via on the website from Saturday to Sunday.

Absolutely! Usually, you will have about 30 minutes of beat time between two relays.
