A long period of inflation can be triggered when the inflaton is held up on
the top of a steep potential by the infrared end of a warped space. We first
study the field theory description of such a model. We then embed it in the
flux stabilized string compactification. Some special effects in the throat
reheating process by relativistic branes are discussed. We put all these
ingredients into a multi-throat brane inflationary scenario. The resulting
cosmic string tension and a multi-throat slow-roll model are also discussed.
