Anyone know what the longest straight stretch of land in the game is (with no wild pokemon)? I know one of the previous games (gen 3 or 4, possibly both) had its longest stretch of land outside the daycare so it was easy to just go back and forth until your eggs hatched.
Skyarrow bridge is definitely the longest, but Route 3 is far more convenient. When making multiple eggs of the same species to get the right nature or ability, it's a faster process to use Route 3. The Daycare man will get your attention when the next egg is ready.

You can also fly to the battle subway and run the infinite circle inside. Its about the same distance, if you use Fly, as the bridge. Volcarona has flame body AND learned Fly, so you wont need to waste a slot.

Go to the battle subway, and position yourself almost to the outside ring, one in. Then just go around. and around. and around! - you can put something heavy or tape down the walk button and just leave it there for days! :D
