Runners without these attributes are not allowed to start! The SI-finger must be initialised outside the starting box by using first the clear control (wait for audio signal which indicates that it is cleared) and then the check control (audio signal confirms that clearing was done properly). At -3 min. the runner enters the starting zone and has to place her/his SI-finger in the check control, while name, chestnumber and SI-number are checked; at -2 min. the runner takes the control description; at -1 min. the runner takes place beside her/his map box; on the signal of the start the runner takes his/her map and on the fifth (= longer) beep he/she starts. If there is a start control it is the responsibility of the runner to place her/his SI-fnger in the start control before leaving the start box.

  • There will be no classification for the guided W-10B and M-10B (from one or more guided runs).
  • Each runner gets points every day he/she participated according to the Scottisch system (the time of the winner is divided by the running time and the quotient is multiplied by one thousand. Rounding happens upwards. The winner obtains so one thousand points).
  • The four best results (points) per participant are eligible for the final ranking.
  • Participants who take part less than three days and gain 1000 points, might be taken out of competition.
