Max possible speed in pathfinder?

So a friend and I were discussing speeds in pathfinder. He thought the max speed was about 600 ft per round. I thought there might be more buffs for this though. So how fast could a character built exclusively for speed go?

Limits

  • Speed must be reached using only feats, abilities, and racial traits. No spells allowed and it must be done by a playable race in the core books.
  • Any level
  • The character may not use items to enhance speed.
  • Core Rulebook only
