Below are the guidelines for how the League will conduct races and events if the weather or other situations arise that interfere with risk management policies.

Our primary considerations are the safety of riders, support staff and spectators, and potential damage to the venue and trails. Any decisions regarding canceling, postponing or altering race start times, lap lengths, number of laps, etc. will be made jointly by the league director, chief referee and the land manager. Often this decision cannot be made until the morning of the race due to the unpredictable and rapidly changing nature of severe weather.

TheLeague will make every attempt to notify the racing population as soon as possible via website updates and social media.


  • Races are held on their scheduled dates unless the race course on the day of the race is deemed unrideable and dangerous.
  • The League will have the option to alter the start of a race from its published times if the weather has created dangerous conditions.
  • Communication of delays, changes in start time, courses, etc. will be made by the League as follows:
    • On the league website prior to the race day, if possible;
    • Via social media;
    • Over the public address system on the race day.
  • Courses and/or lap lengths may be altered or shortened due to weather conditions. Last minute changes will be broadcast to riders at the start of each wave via the race announcer. If conditions require a change in the number of laps during a race, a person will be stationed at the lap line advising riders of the change.
  • All racing will stop immediately in the presence of dangerous circumstances, as signified by the chief referee, race director and/or EMS staff. Racing may continue once the league director, chief referee and the head timer have conferred.
  • Re-starting a race that has been stopped:
  • Depends on schedule and number of laps completed, the race may be declared over;
    • If a race is stopped due to hazardous conditions, standard scoring is to count only the laps completed, and to score riders who had to evacuate as pulled.
  • If time permits, racers will be able to resume laps beginning from the lap line.
