12 rules for a safe and enjoyable long-distance ride

  1. No drafting: The race is self-supported, which means you must arrive at your destination without the benefit of a draft from another rider (or vehicle), unless you are riding in pairs or teams of four, where drafting is allowed. Pulling in will result in disqualification.
  2. Follow the route: The route will be provided as a GPX file and it is imperative that you follow it from start to finish and not deviate from it. If you need to leave the route for a refueling or mechanical problem, you must return to the point where you left the route and continue from there. The route is on road and requires a suitable road bike with normal road bike tires. Some deviations on bike paths are possible, but they are passable with a road bike.
  3. Check point / Base de Vie: the base de vie located in Chantilly will allow you to rest/sleep, shower. You will be welcomed with warm smiles and encouragement. It is important to rest and take a break when you need it, we suggest you do not use only the checkpoints. Sleep when you need to, camping, bivouac, hotel, b&b, all are allowed according to French laws.
  4. Helmets, lights, working bike: It is mandatory to wear a helmet on your bike, to have working lights, with a rear light on all the time and a front light on from dusk to dawn. The bike must be in good mechanical condition, with working brakes and properly profiled tires. Any mechanical problems on the road must be fixed by the participant.
  5. Autonomy: No outside assistance is allowed. All trips must be made by calf power. Vehicle assistance is not permitted during the race. If you drop out or decide to withdraw from the race, you must inform the race headquarters as soon as possible. You will not be allowed to use the checkpoints.
  6. Respect the rules of the road: Respect the rules of the road, drive on the right, stop at red lights and stops. Treat other road users with respect: yield to pedestrians on bike paths. Be respectful of other cyclists, our goal for this event is to be inclusive. We want to encourage new cyclists to discover the world of ultracycling. So be respectful on the road and let’s build a great community together.
  7. Think Green: Whenever possible, travel to the start and finish by train and boat. The route has been planned to allow for this possibility. Do not leave a trail, the route will take you through some of the most beautiful and green areas around the Ile-de-France. Please respect French laws and do not leave any waste behind.
  8. Insurance is mandatory: It must be taken out by each participant. If you come from abroad, rescue and repatriation are mandatory.
  9. Time barriers: 300 km > 24 hours, 500 km > 40 hours, 1000 km > 3 days. Any competitor who does not reach the finish line before the end of the event and who wishes to continue independently will be able to do so only after informing the race headquarters. He will do it under his own responsibility and independently.
  10. Be prepared: By entering an ultracycling event, runners accept the extreme risk that comes with it. Riders are responsible for their own safety and must ensure they get adequate rest (take a break and sleep). Safety depends solely on the rider’s ability to adapt to storms, bad weather, mechanical problems, bad phone signal. Riders agree to wear a GPS at all times.
  11. Challenge yourself: The routes are designed to allow multiple entries into ultra cycling. If this is your first long-distance event, you can start with the 300 or 500 or, if you’re a regular, head straight for the 1000. It’s important to be aware of what you’re undertaking.
  12. Smile: The hard times will be the ones remembered the most!This is an overview of the rules to understand the philosophy of the event.
