The best way to swim a 100 is to remember that the first 25 is going to be fast because of the start,so you don't have to push as hard as the last three laps.  After that try to think about building each 25 up so each feels faster than the last. For example- lap two should be fast but smooth, the third should push a little more and the last should be as fast as you got.  A key to fast sprinting is to have good streamlines off the turns so you can go under the wave that is following you.
