The B777 low drag/ low noise approach is flap 5 gear up. In still air this can be maintained to 2000ft (about 7 miles) on a 3 degree approach. At this point the landing gear is lowered and flap 20 selected. Airspeed reduces and at about 1500ft (5 miles) landing flap can be selected. The speed then reduces to Vref+5 just before 1000ft, which is the first 'approach gate' for a stabilised approach. A tailwind or headwind would move the gear selection point up or down the approach +/- a mile.
