The first kilometer/mile

What is the best way to drive the first kilometer/mile to reduce both wear on the cold engine and fuel consumption?
  1. Pulse and engine-on glide, like I always do? The glides are usually longer than the pulses, so the engine is idling cold more often than not, which it really shouldn't be doing.
  2. Pulse and EOC? The engine isn't running cold then, this also extends the distanse before reach operating temperature. In my case, before killing the engine I'd have to wait for the turbo to cool down after each pulse, so I'd still be idling the engine. And once I'm ready to kill it I'll almost be ready for the next pulse.
  3. Steady driving in gear? This may speed up warmup time, but the engine won't be operating in the most optimal rpm/load range, so I'll burn more fuel.
  4. Other ideas???
