Has anyone ever hiked a 8k meter/26k ft. mountain?

Just read into thin air by Jon Krakauer and it has piqued my interest in doing some big mountain climbing. Does anyone here have any experience climbing any of the huge mountains in the world, or even some of the 2nd tier type mountains like Kilimanjaro, Denali, or Vinson? Any info or trip reports would be greatly appreciated, as I think I am aiming for a Kilimanjaro trip about a year from now. Thanks!
