There are a couple places where you can watch the CrossFit Games 2019, and in this post you can find an updated list of streaming sites:
This list will be updated whenever there is a noteworthy stream online. You can also find more streams at the CrossFit Games website.
You should probably give the official website a look too. HQ will provide the so-called world feed which is an unedited basic feed of the action which others can then use to commentate or provide additional information around and maybe build a show themselves.
Remember, this is the first year with this world feed so don’t build up too much hype. Visit different feeds and pick the one you like and which provide the most value to you.
If you spot a mistake or if you feel like one of the points need more clarification, make sure to get in contact.
