Code of Conduct


All participants, attendees, pacers, and crew members must adhere to the following rules.  By participating in or attending an event, you agree to adhere to these rules. Violating any of these rules, including violating the ECS Code of Conduct, will result in runner disqualification, as determined by The North Face in its sole and absolute discretion.

ECS Code of Conduct

As an athlete competing in a The North Face Endurance Challenge Series (ECS) event, I agree and attest that the following statements are true:

  • I understand that The North Face is committed to clean sport and does not condone the use of performance enhancing drugs or banned substances at any level of competition.
  • I understand that The North Face recommends that all athletes competing in any The North Face event and sport in general should educate themselves on the anti-doping rules and banned substances established by the World Anti-Doping Agency (WADA) and on other anti-doping rules and policies, including those referenced below.
  • I understand that athletes who have been banned from competition by the International Association of Athletics Federations (IAAF), the World Anti-Doping Agency (WADA), the U.S. Anti-Doping Agency (USADA), any national sports federation, or a similar organization identified by The North Face, for a violation of applicable anti-doping rules or policies, are prohibited from competing at any ECS event while the ban is effective.
  • I understand that once such ban has been served and officially lifted, the athlete may compete at any ECS event, however, such athlete (1) will forever be ineligible to receive prize money, awards, podium recognition, or overall or age group competitive rankings at any ECS event, and (2) may not participate in the ECS 50-mile event elite field (I also understand that if a ban is overturned on appeal or otherwise vacated, the athlete will be eligible to compete on the same terms as all other athletes and will be eligible for prize money, awards, etc.).
  • I understand that The North Face shall have sole and absolute discretion in determining whether a qualifying ban was imposed.
  • I understand that this policy is subject to change by The North Face at any time.

I agree that if I am ever banned from competition by the International Association of Athletics Federations (IAAF), the World Anti-Doping Agency (WADA), the U.S. Anti-Doping Agency (USADA), any other national sports federation, or a similar organization identified by The North Face, for a violation of applicable anti-doping rules or policies: (1) I will forfeit any ECS event in which I competed while the ban was effective and return any associated prize money, awards, etc., (2) I will forever be ineligible to receive prize money, awards, podium recognition or overall or age group competitive rankings at any ECS event, (3) I will forever be ineligible to participate in the ECS 50-mile event elite field, and (4) The North Face will have sole and absolute discretion in determining whether a qualifying ban was imposed.

  • Each runner’s official race number must be worn prominently on the front of the body and must be easily visible at all times.

  • Runners must follow the marked trail at all times. Any runner departing from the official trail must return to the point of departure on foot before continuing.

  • If you abandon the event without notifying a volunteer at an Aid Station, you will be responsible for your own safety and will be responsible for paying all related costs and expenses if a Search and Rescue team is sent out on your behalf and you are not on the race course.
  • All cut-off times will be strictly enforced. Runners must depart the checkpoint BEFORE the cut-off time. Runners that do not clear the aid station checkpoints within the established time limits will not be allowed to continue the race.  Cut-off times can be found in the pace charts included in the distance specific course guides.
  • Officials have the right to remove any runner, pacer, crew member, or attendee from the course deemed necessary for their safety and the safety of all others.

  • Each runner must complete the entire course under his own power. No physical or mechanical aids are allowed, including but not limited to ski poles, hiking sticks or crampons.
  • Runners are responsible for the actions of their spectators, crews and pacers. Everyone associated with the event must comply with all rules and regulations issued by the race staff. For specific pacer and crew rules, please consult the course guide for your specific race location and distance.

Trail Etiquette:

  • Absolutely no littering. If you, your crew, or your pacer abandons anything (e.g., drink cups, gel packets, banana peels, clothes, etc.) on the race course, you will be disqualified and banned from entering future Endurance Challenge events.
  • Only attempt to pass another runner when it is safe for both you and the other runner to do so. When passing, make every attempt to pass on their left, unless it is unsafe. Announce your intention to pass by saying, “passing on your left” (or right, if it is unsafe to pass on their left). Provided it is safe to do so, yield to any runner who announces his/her intention to pass, by stepping off the trail.
  • Be prepared to share the trail with runners coming from the opposite direction.


  • Runners must refrain from any act of unsportsmanlike conduct.
  • No weapons, personal alcohol, glass bottles, smoking or illegal drugs will be permitted on the course, aid stations or Finish Festival.
  • Runners crossing the finish line after the official cutoff will not be listed as official finishers.
  • Pet Policy: The local parks and venues hosting the event will determine whether pets are allowed on premise at the event. Please check their individual policy before bringing your pet to the event. If pets are allowed on premises, they must be kept on a leash at all times. Pets are not allowed on-course during the race or on any race transportation buses unless approved in advance by The North Face Endurance Challenge team. Please contact us at for questions regarding the pet policy.
  • I understand that The North Face and Endurance Challenge are not responsible for lost or stolen gear bags or property.
  • Runners, spectators, pacers and crew may only park in the designated parking areas approved by the event.  Please check the course guides and parking and shuttle information page for your event for more information.
