Rules and Common Sense

Rules of the Road

  1. All riders are required to wear an approved helmet and cannot remove it at any time while riding.
  2. No support or follow vehicles are allowed. Aid stations will be well stocked and able to handle participant’s needs.
  3. Riders must ALWAYS obey traffic laws and strictly obey any law enforcement persons or official ride personnel. In the interest of your own safety, you should always assume the same level of vigilance in riding your bike during the event that you would under normal circumstances.
  4. When passing other riders, use common sense and pass on the left and let yourself be known when doing so. After you pass, resume riding as far right as safely possible. DO NOT PASS riders or vehicles on blind corners.
  5. Public urination or exposure is, as always, a definite NO-NO. Anyone caught using anything other than a porta-head in the start or finish area or appropriate nature-break facility will be disqualified from the event.
  6. You are responsible for your own mechanical needs during the event.
  7. Utilize the aid stations and stock up with the necessary fluids and food you’ll need to get yourself to back the finish area.
  8. Be prepared for extreme changes in the weather, this is the high country. A light windbreaker at the very least is a good idea. Sunblock is also a must at these altitudes. Ride will take place rain, shine, sleet or snow.
  9. Entry Refunds? There are no refunds.
  10. Headphones/ear buds are NOT permitted during a ride.
  11. Each rider is classified according to their age as of December 31st, the year of the event.
  12. Equipment: Bicycles cannot have handlebar extensions or additions that mount anywhere EXCEPT the end of the handlebar (ie., bar ends on standard MTB handlebars are acceptable) in other words, NO AEROBARS!
  13. Riders must respect the directions of all course marshals at all times. If you’re told to stop by a course marshal, moto official, uniformed officer or otherwise, YOU MUST STOP!
  14. All riders must attend the “riders’ meeting” held at the staging area 15 minutes prior to the event.
  15. The responsibility of keeping on the prescribed course rests with the rider. A rider may not leave the prescribed course unless ordered to do so by public authorities or a ride official.
  16. Shortcutting and/or cutting trail switchbacks or course is not permitted and may result in disqualification. A rider is required to stay on the designated route. It is the rider’s responsibility to know the designated ride route. Lack of tape or barriers will not constitute an excuse for cutting the course.
  • Laws and ordinances of appropriate jurisdictions shall be observed during participation in the event.
  • A rider may be suspended for damaging or destroying public or private property. A rider may be held liable for all cost associated with the damage or destruction.
  • Lost & Found officials reserve the right to make changes to the course, delay start times and/or postpone the event as necessary for safety or security purposes or at the request of permit issuers.

The Lost & Found course features a perfect blend of pavement, dirt road, gravel road and historic railroad grade.

  • Riders must obey all applicable traffic laws during the event and are encouraged to use common sense, keep their head up and stay in their lane of travel. At no time will there be a closed road.
  • For the first 10 miles (first paved section) riders in the peloton will have full use of the right lane of travel, but cannot ride left of the yellow line into the oncoming lane at any time during the ride.
  • Once the route changes to dirt road, riders must obey all traffic laws and use common sense, keeping their speed under control.
  • Riders should expect vehicle traffic on all roads, along with ATVs, motorcycles, livestock and wild animals. Stay in your lane and follow the rules of the road.
  • Once a rider is dropped from the main peloton they must ride as far right as possible in single formation. This applies to both the pavement and dirt sections. 


During a “Rolling Closure”, vehicle traffic will be stopped and controlled by course officials and/or law enforcement to ensure rider safety and to keep the peloton moving swiftly. Once the peloton has passed through, the intersection will re-open to vehicle traffic. Rolling Closures are estimated to take no more than 10 minutes at each intersection. Racers riding behind the peloton must obey all rules of the road, as there will be no Rolling Closures in place.


 Please note that for rider safety and permit compliance, we must enforce strict cutoff times at the listed locations and times. At racer registration – 3:00pm to 7:00pm on Friday 6/1 or 6:00am to 8:30am on Saturday 6/2 – you will be asked to verify your understanding and agreement to these conditions:

  • 12:00 PM: All 102 mile riders must turn off to 65 mile course at Aid Station #4 (N) - 31.6 mi
  • 3:30 PM: All 102 mile riders must get into sag vehicle at Aid Station #6 (S) - 63.5 mi
  • 4:30 PM Vicious Cows (X) - All 102 mile riders must continue South on County 111 Road - 78.4 miles
  • 4:30 PM: All 65 mile riders must stay right on Beckwourth Genesee Rd (No Vicious Cows) - 37.5 miles

Note: There will be a dedicated course sweep for all course lengths.

We highly recommend racers to download and register yourself in the RaceJoy App that provides live GPS tracking of your position on the course (or off of the course). RaceJoy allows us to confirm the progress of the race and detect any racers that may have strayed from the course, or called it quits before the finish. You can also share your position with your friends and loved ones who would like to track your progress during the event, and even track your competition live on your phone

Ride Map

If at anytime an STBS staff member, or a member of the emergency response team, determines a rider is physically unable to complete the event within the allotted timeframe. You must accept a ride back to the emergency response center at the Portola Start/Finish area.

  • If you do not make the cut-off time or are unable for any reason to finish, please DO NOT go through the finish line as it will foul-up our results!
  • Riders who are not capable of getting back to either the start or finish areas under their own power will be transported by an event “sag” vehicle.
  • Course officials reserve the right to remove and “DNF” any rider from the event that is deemed incapable of safely finishing the course for any reason.
