Well, it says so with the tickets for the first competition scheduled on a particular day, for instance Men's SP. "! By purchasing the ticket to attend the event scheduled for March 22, you will be entitled to attend both the training sessions starting at 6.00 am and the official competition starting at 10.00." So... pretty sure?Are you sure you can enter the practices if you have the ticket for the competition of the day? Then that can be a good idea... :agree:
But of course that only goes for the first competition, because otherwise they'd be overbooking practice seats (you cannot include a seat for early morning practice with the morning/early afternoon competition *and* the late afternoon/evening competition).
That said, I give you no guarantee whatsoever about where you can sit. I don't know how strict they (the volunteers?) will be checking the location of your seat / allowing you to enter the arena anywhere other than in the general area of your seat. So there's that to consider.
