1. Sector Times will be based on timed segments along the route of the Grinduro.  SAFE & FAST is the Key!

2. Riders must carry all the supplies/tools they need for the rides. Outside support is only allowed for riders that need to be removed from the course.  No support/drinks from a moving vehicle is allowed.

3. Riders are responsible to learn/know/navigate the course. Digital Versions of the courses are available for download/upload to cycling computers/GPS devices. Printed Cue sheets will be available at check-in. 

4. Rider Conduct: We require that athletes conduct themselves in a manner that is sportsmanlike and fair. Any activities deemed harmful to the event or community will result in disqualification and the rider will be asked to leave the course. 

5. Bike Racing/Riding in this manner is dangerous and should be restricted to experienced riders. Please use caution and utmost concentration when riding these courses. You are responsible for your safety and the riders around you.

6. Riders are not allowed to advance on the course by any other means than the two wheeled bicycle that they started on.   

7. Drafting is allowed between registered participants only. It is not allowed to have a non-participant rider along the route to draft with. This will be enforced by fellow participants, in which two witnesses will serve as enough for a DQ.

8. All roads on the course, paved or dirt are open to traffic. Please use your head and brakes. Yield to traffic if you don't have the right of way. Keep in mind that when going from a dirt road to a paved road you will never have the right of way.

10. If you are badly injured while on course please call 911. Please don't be afraid to give assistance to other racers. Remember that the next accident could be you and professional help can be too far away.  Some of the areas of the courses are pretty remote so cell service is limited. This is why we suggest that all athletes carry a small first aid kit with them. 

11. Bicycle restrictions: There aren't many as we want this to be as inviting as possible to the masses.  Two working brakes are required even for the single speeds.  Aero bars are allowed although most roads on the course would make them useless. Cross, Gravel, and Mountain Bikes and yes even E-Bikes are all allowed. The best suited bike for the courses will be a cross or gravel bike. Suggested gearing is at least a 36-28. There are pitches on gravel/dirt roads at 22% so plan accordingly.  

12. All timing will be done with the RACE|RESULT Pro Chip Timing System and this data will be sent back to the finish line remotley and instantly. This will allow us to know where athletes are on course and provide the timing data for the segments.  Each athlete must wear the provided neoprene ankle strap with timing chip. This must be returned to the event registration tent at the completetion of your adventure. Riders who fail to return the timing chip will be charged $100. We will have volunteers at the finish line to retrive them from you so you shouldn't be able to forget unless you abandon and don't cross the finish line.
