It’d be interesting to hear from any of the organisers who sometimes pop in here.
From Southern Enduro’s point of view.
The Series: on December 1st we release 100 tickets for the full series with as small discount. If riders don’t have the have the cash on the 1s Dec we release 150 more tickets 2 mouths before each race.
The QECP Mash Enduro is 2 months before the race.
The QECP Day and Night Enduro is 2 mouths before the race.
So as a general rule we go for 2 mouths before race as typically that’s when we have to start paying deposits and booking stuff.
The exception to that is the Southern Enduro Champs where we release the tickets 6 months before the race (on 1st Dec) This is because its a much bigger event and have to book and pay deposits much earlier.
