Jack,
If you do not have any ATC constraint, on a continuous descent and depending on the wind. I'll usually start reducing speed from 250kts at 18nm from touchdown. 12nm conf 1, 8nm conf 2, Gear Down at 2000fts (between 6 and 7 miles), then then configure for landing in sequence and ldg checklist.
With a tailwind, follow de facto's advice.
