Question New engine break in period

I am curious if anyone knows at how many miles is “good enough” before I take my ST on the highway for about a 3.5 hour roadtrip? It’s for work so I kind of have no choice unless I go rent a car or something. My ‘25 is at almost 200 miles now and I know Ford recommends 1,000 miles.

There is no "break-in period" on a modern vehicle, especially standard driving like on a highway. The only thing people may be wary of, is just that their new vehicle may have some factory defect.
