You need to edit your last post. You misunderstood something. Krillin said that an olympic swimmer can finish [b]ONE mile[/b] in fifteen minutes, but this is 100 miles. So it would take an olympic swimmer 25 hours if they swam without getting tired. Everyone here is supposed to be stronger than olympic athletes, hence why he estimated it would take most everyone is twelve to fifteen hours. 

Also, you're assuming that you can jump, skip, and hop over the other martial artists that are here, when actually, almost everyone here is on the same level, in terms of strength. :)
