According to a press release from the CrossFit organization in October 2018, the CrossFit Open is slated to open registration today (the 10th of January).
CrossFit Headquarters hasn’t said much on the topic, short of recently releasing the 2019 CrossFit Games rulebook
We assume, like previous years, past participants should get an email and notification if they have the app installed once registration is live.
According to rumors from Morning Chalk Up, the custom leaderboard is coming back.
The official kick off date for the Open is Thursday, February 21 and will run for five weeks. TBD on the number of workouts though; HQ can be sneaky like that.
