I wouldn't reccommend running all the way to Ka on the "running of the bulls" because you will definetly get tired. I always do it and I'm still out of breath even when I get on the ride, but if you want go for it! My personal favorites are: El Toro, Kingda Ka, Great American Scream Machine, Batman the ride, and skull mountain. If you go during a week you will be able to do everything in one day. It will be expensive and I'd reccommend doing El Toro in the last row.
