Two weeks ago, the show had been canceled for the second year in a row. Last year the cancellations was due to corona and now due to EHV-1. The show was supposed to take place this month but the FEI imposed a shutdown of all international competitions until 11 April. 

The new dates would be from 23 April until 25 April, on the condition that the EHV-1 doesn't get worse. The decision was made by the umbrella organizations and the veterinarians of the KNHS and the FEI.
