Driving Times during Extreme Weather

When the weather forecast institute predicts temperatures of 27 degrees Celsius or higher for the next 24 hours, this is considered extreme weather. (example, Dutch standard)

To provide horse owners with guidance on how to deal with extreme weather conditions, the Sector Council for Horses has decided to draw up a ‘Protocol for extreme weather conditions for horses’.

  • The technical delegate and the chairman of the jury may adjust the times/speeds in the event of severe weather and/or terrain conditions. (Dutch KNHS regulation)
  • In the event of exceptionally hot and humid weather, the time allowed for the mandatory rest period (after the A course) may be extended by the jury on the advice of the competition veterinarian. (Dutch KNHS regulation)

Course time calculation

In the event of a heat protocol/extreme weather, you may need to calculate travel times based on speed.

For this purpose, there is the Driving Time Calculator – Distance/Speed, link to the calculator at the end of this post.

To calculate the time allowed for Route A,

  • Enter the length of the route in km (distance)
  • Enter the speed in km/h (speed)

Now we will calculate the minimum time for Route A. The minimum time for Route A is 2 minutes* less than the time allowed:

  • “Min” = 2
  • “Sec” = 0

The complete table with the times for Course A is now displayed.

Now do the same for Course B, except that the minimum time for Course B is 3 minutes* less than the allowed time.

* Always double-check the correct times with the local rules/regulations

Course Times (Dutch KNHS competition rules for driving 2025-94)

  • The time allowed for each course is calculated according to the average speed chosen for that course in accordance with Article 452.6. b. c. d.
  • The minimum time for course A is 2 minutes less than the time allowed.
  • The minimum time for course B is 3 minutes less than the time allowed.
  • The maximum time for course A and the transition course is equal to the time allowed plus 20%.
  • The maximum time for course B is equal to twice the time allowed.
Distance / Speed Calculator

To refresh the data in the tables after a change, change the time between the minimum and maximum times.

This calculator is still under development. The results align with the regulations, but the functionality remains somewhat cumbersome. We are currently working on this.
