More than a running race, Run Mate by Core Lean also offers non-race challenges to be completed as a team, the best of which will be rewarded. Details of the challenges will be communicated soon.

  • Become the king of the Lake Geneva Quiz

    How does it work ?

    The quiz is made up of approximately 26 questions, 1 per relay point.

    When you visit each relay point, you will find a sheet with 1 question and 3 answers to choose from (1 true, 2 false). You answer it and that's it.

    To answer each question, simply scan the QR code on the question sheet with your phone to be redirected to the online questionnaire. Don't panic, there is no need for an app to scan the code, you can scan it with the camera function. You answer it and that's it.


    The team with the most correct answers will win this challenge.

  • Dress up!

    How does it work ?

    Dress up. Bring out your craziest outfits. Before the start of your race, in front of the majestic Lake Geneva, your team will have their photo taken to immortalize this moment.

    Once all the teams have left, a photo album will be published on our Facebook page with all your team photos. You will then have a few hours to share your photo with everyone and make sure it gets as many likes as possible.

  • Take your trash...get ready...Pick up your trash!

    During the race

    1. Collect your compostable waste

    On race day, your team will receive 2 compost bins in which you can collect green waste: apple cores, banana peels, etc. All leftover meals can go in*!

    Bring your bins back upon arrival at the Energiapro stand so that they can be checked and weighed.

    2. Weigh them upon arrival

    The team that collects the most organic waste will win a prize.

    After the race

    3. A second life and just as much energy!

    The waste collected during the race will be sent to Ecorecyclage, a biogas production plant near Morges. There, they will ferment in a digester and be transformed into biogas.

    4. Multiple uses

    The biogas will then be injected into the distribution network served by Energiapro. It will be used for heating, cooking, or as fuel!

    * fruits, vegetables, peelings, fish, shells, dairy products, meat, leftover raw or cooked meals, coffee/tea grounds (no capsules)

  • Run the segments as quickly as possible

    How does it work ?

    Speed competition on three segments of the course. All you have to do is run these segments as quickly as possible.

    Signs will indicate the start and end of each segment.

    The segments

    The segments are still to be defined 😊


    There will be a ranking by segment but it is the team which is the fastest in the different segments combined which will win the challenge.

    Once all teams have completed the three segments, the result will be listed here and broadcast on our social networks.
