6.6 WEATHER CONDITIONS
6.6.1 Temperature
Biathlon competitions must not be started if the air temperature is
colder than minus 20 degrees Celsius measured at the coldest part
of the site (range or course), 1.5 m above ground.
6.6.2 Wind Chill
Regardless of temperature, wind chill must be considered before
starting and during the competition. In the case of a high wind chill
factor, the Competition Jury, in consultation with the IBU Medical
Delegate or the Competition Physician, will decide whether to start or
continue the competition. Changing of the course to be skied may
also be done to avoid windy areas. The following Table 2 shows
wind chill temperature equivalents.
NOTES TO TABLE 2
1. This is only a guide - the decision to start or not will be made by the
Competition Jury in consultation with the IBU Medical Delegate or
the Competition Physician.
2. Top shaded line is the -20 degree Celsius equivalent boundary.
