Official Rules

  • Racers are responsible for knowing and following the rules of each series event. Many of the following rules are common among all the participating series events.
  • Only one bike allowed (no back up bike). Racers may do any repairs to their bike with items they have with them, and major repairs may be made at designated aid stations with the assistance of team crew or family. Any parts on the bike may be replaced but the bike must be the same bike you started the race with.
  • Racers must complete at least three races to qualify for series recognition and awards.
  • After three races, all racers who complete more than three races will have their lowest score(s) dropped so that only the best three races will be figured into the standings giving racers an opportunity to improve their scores during the season before the final race. Series results will be available after each event at
  • NUE Points will be calculated as follows: Racers will receive one point for 1st place, 2 points for second place, 3 points for third place etc. Lowest points win! In the event of a tie score before or at the final Championship race: Racers must compete head-to-head in the final NUE series event to break the ties. Note: Although it is not mandatory to compete in the final race to be eligible for series awards, it is mandatory to complete the final event to break ties. Ties will NOT be broken by evaluating finish times! If any racers with tied scores fail to complete the final NUE Series event, the tie will stand. If one racer completes the final event, that racer will be scored ahead of the other tied racer. If a racer comes into the championship with 2 races and the third race creates a tie, the winner at the head-to-head championship wins. All racers must have completed at least 3 races to qualify. This third race can include the final championship race at Big Bear Grizzly 100.
  • At many races with loops, racers may only leave the racecourse (perhaps to go to their car or the restroom) at the start finish area only and must check in and out with a race official.
  • At all races, if a racer finds they are off course (whether by their own mistake or even sabotaged course markings) they MUST return to the point where they got off course and continue FROM THAT POINT. It is always the responsibility of each racer to watch the course for turns and carry any maps or directional material provided at each race. Any racer that is proven to have been off course without returning to the original spot they went off course will be disqualified.
  • Aid can be given by anyone at any of the races but only at designated aid stations that allow Crew Access. Anyone, other than registered racers who provide outside assistance to a racer outside of designated aid stations or crew access locations will result in disqualification of the racer.
  • Singlespeed bikes must be single speed (no flip flop hubs with 2nd gearing option).
  • Cut off times may be created to avoid night rescues and to allow the race to be over by dark. Check with each race venue for posted cutoff times.
  • Spectators may watch anywhere along the course but are asked to not ride the course during the race. Any spectator riding along with a racer, as support, is not allowed and will disqualify the racer.
  • DNF… If you drop out of the race, you must notify a race official. Everyone needs to be accounted for!
  • Please do not litter! Used gel packs are the worst to clean up. Leave no trace. Littering of any kind is strictly prohibited during the race. You may be disqualified if there is a report that a racer (you) is not respecting this rule.
  • The land we share at many of these races include State and National Forest Land. It is imperative that we show them we can hold events like this while being good stewards of our trails. Please pocket your gels, bars, baggies, bottles, tubes, etc. DO NOT THROW ANYTHING ON THE GROUND! Pack it in, pack it out!
  • Each participating race director is responsible for the results of their own event(s). In the event of a protest, Racers must appeal to the race director of the particular event to file a protest. The National Series will not be responsible for resolving individual protests for participating events and the race director’s decision will be final.
  • For the sake of the integrity of the National Series, no participating Race Director of the National Series will have the right to alter race times for any reason! This includes deducting or adding time to a racer for any reason. A racer’s time must be based solely on actual time. The racer either completed the entire course or is Disqualified (DSQ) for not completing the entire course. This rule will ensure that the results of the national series will be based strictly on finish times and the series will not be decided by a ruling by any participating race director.

NUE SERIES DOPING POLICY: Level Playing Field for ALL Racers

  • Racers who are under suspension for doping are not eligible for NUE Series points. Racers who are accused but not convicted or suspended for doping are allowed to compete until a ruling is announced. If a racer is convicted of doping during the season, all NUE Series points for the current season will be forfeited and the racer will not be eligible for series awards or recognition. Once NUE Series standings are final, they are final. NUE Series reserves the right to test racers for doping.
