Data collection (essential and additional data) on race day, athlete demographics, athlete race performance, course geography and environmental conditions on race day

CategoryMinimum/essential dataAdditional data
Race day data

  • Official cut-off (finish) time (hh:mm:ss)

  • Number of registrants (entrants): the number of athletes who register to participate in the event

  • Number of starters: the number of registered athletes who start the event

  • Number of finishers: the number of registered starting athletes who finish the event

Athlete demographics (individual athlete data)
  • Age (on registration day)

  • Sex

  • Height (cm)

  • Body weight (kg)

Athlete race performance (individual athlete data)
  • Race discipline (if applicable—different sporting codes)

  • Race registered for (if applicable—different race distances)

  • Race starting time (hh:mm:ss)

  • Race finishing time (hh:mm:ss)

  • Calculated total race time (hh:mm:ss)

  • Previous participation in this event type (number of previous races in this event type)

  • Number of times previously participated in this race

  • Personal best time for this race (hh:mm)

  • Qualifying time for this race (if applicable: event and time—hh:mm:ss)

  • Races participated in (in the previous year) (n)

  • Date of last race participated in (dd:mm:yyyy)

  • Personal best time for this event in the last 12 months year (hh:mm:ss)

  • Average regular training in the last 12 months (h/w)? Split times (distance (km) from the start line should be recorded in conjunction with the split time (hh:mm:ss))

Geographical data of the course
  • Total course distance (m)

  • Individual course sections (if applicable, eg, triathlons) (m)

  • Altitude (m) (mean, range)

  • Total elevation of the event course (m)

  • Change in elevation (m)

  • Type of surface of the event course (if applicable) (tar, asphalt, off-road, grass/gravel, sand, and so on)

  • Nature of the event course surface (wet, dry)

Environmental conditions on race day
  • Ambient temperature (°C)

  • Relative humidity (%)

  • Wind speed (km/hour)

  • Wind direction (°)

  • Cloud cover (%)

  • Precipitation (mm)

  • Wet-bulb globe temperature (WBGT) index (°C) (at the start and finish of the race)
