  • What is Run Mate by Core Lean Léman?
    Run Mate by Core Lean Lake Geneva is a relay race (2 to 9 runners) around Lake Geneva for 2 days and one night. But before being a race, Run Mate by Core Lean is a group adventure.
  • How do relays work?
    Put all your Mates in a van (or two cars if you don't have a van) and drive them around 218km around the largest lake in Europe! There will be 26 relays in total, between 4 and 15 km each, which will be around 25 km per Mate (if there are more than 8 of you) with varying degrees of difficulty depending on your organization. Only 1 runner is on the course at a time while the other Mates rest, encourage the runner or take on the challenges! While the runner is on the course, the van must go to the next relay point to wait for him. In fact, the Mates only have telephone contact with the runner
  • How to organize yourself for the relays?
    FREEDOM: this is the key word of this concept. You can organize yourself however you want. A runner can run only one relay during the entire race. But a runner can also run 2, 3 or 4 relays in a row if they feel capable. There is not a maximum or minimum number of relays to be completed per runner.

  • What happens if our team is too slow compared to the others during the race?
    We have set time barriers corresponding to the theoretical passage times of the last rider. If a team exceeds the time barrier, the organization reserves the right to ask an off-time team to “skip” one or more relays (therefore not to run it and to go with your vehicle to the relay point indicated by organization). This will automatically result in non-classification (DNF) of the team but the team will still be allowed to finish the race.
  • What happens if our team is too fast compared to the time communicated during registration?
    If you are too early on the communicated time, the organization reserves the right to stop a team at a relay point for an indefinite period in order to ensure the proper management of flows on the route and to respect health rules in force. The stopping time at the relay point will be deducted from your overall time.
  • Can we replace a Mate who is running if he cannot finish his section?
    Yes, you will simply need to retrieve the GPS beacon and pick up where your Mate left off.
  • What to do if a runner is injured during the race?
    The runner calls his team to come pick him up. As the organization of the relays is free, any rider from the team can replace him and the injured rider can join the vehicle. The replacement runner resumes the race at the place where the runner left and picks up the marker of the Mate who was running. In the event of a life-threatening emergency, call one of the emergency numbers depending on the country you are in. (Life-threatening emergency in Switzerland: 144 / Life-threatening emergency in France: 15) If there is no emergency you can consult our medical team at each super relay point.
  • What to do if a runner gets lost?
    The organization, via an alert system, will be the first to know if a runner strays significantly from the course. The organization will contact the team captain to explain the situation, the captain will be in charge of contacting his Mate to warn him. If the organization has not yet contacted you, you can call them via the PC Course number (available in the Roadbook). If on a certain section you no longer see signage, check your position on the route using the application.
  • What is the racing protocol?
    Each Mate must respect the highway code and the racing environment. Please refer to our Roadbook so that the rider is safe at all times. The route is not 100% marked, but the main crossings, changes of direction or other unconventional paths will be marked. At night, the markers will be visible.
