Proposal for rules: (to be used as recommendations only for season 2018-2019)
To be applied to all ISMF races (Individual, Sprint, Vertical, Relay)
Measurement of temperatures and wind speed
The race technical director ensures that an accurate temperature and wind speed is taken by a race official with certified measuring equipment (existe-t il une norme?)
Wind speed= fastest speed recorded over a minute, in an exposed place of the transition are, recorded in km/hour. The measurement are to be rounded up ( ie -13° becomes -10° when reading on the chart)
Actual Air temperature: temperature in °C recorded out of the wind and the sun. Rounded up.
Wind Chill Temperature: this is the adjusted temperature as relayed by the chart.
This is to be obtained 20 minutes before the official start of the race.
If the race start is delayed, then the temperatures and wind speed must be re-assessed 20 minutes before the next provisional start time.
The measurements are done on the start area, the finish area and the high point of the race.
The high point is defined as the transition area at the highest altitude on the course.
The race director must then cross-reference the air temperature and wind speed on the ‘wind chill’ chart. He thus obtains the Wind chill temperature of the three points: start, high point, finish.
