Looks like Zwift have changed their minds again re making the event a race ! No mention on whether ZP GC for the event will be maintained through the four months but no update for March yet.
Disappointing to once again start something and not to be able to complete the race [no longer a race, but with Race Results ?] GC series.
Updated information on ZwiftInsider:
UPDATE March 26, 2024: in March, Zwift reconfigured these events to be rides with a results screen at the end, instead of standard races. They’ve told us this change was made to make the L’Etape du Tour events feel more like sportives than races.
