The date for the 2018-19 FIA World Endurance Championship Prologue has been adjusted, in an effort to better accommodate drivers and teams taking part in the Total 24 Hours of Spa.
Confirmed in a memo sent to competitors on Monday, the official pre-season test at Circuit de Barcelona-Catalunya has been moved forward by one day and will now take place on July 23-24.
Originally, the second day of the two-day mandatory test had fallen on the opening day of track activity at Spa, which had caused issues for several competitors taking part in both the WEC and Blancpain GT Series.
Per the bulletin, WEC teams will be allowed to load-in on Monday, July 22, the day following the European Le Mans Series round at the Spanish circuit.
The pre-season test, which comes five weeks after the 2018-19 season-ending round at Le Mans, has come under criticism from some competitors, although the WEC has defended its significance in the calendar.
