Is There a Better Application for Less, Longer Sessions?

If you're doing something like a lot nger, like an ultra marathon, there may be a better application for fewer, longer sessions. If running more frequently for shorter periods of time allows you to run faster at a given intensity, then that's likely going to yield greater performance returns. O next is what is your advice for preparing for steep climbs and technical, rocky trails if the area you live in doesn't have either? How or, in other words, how pare for a mountain race from the mid west? A excellent question. I don'think it's necessary right or wrong answer. It's going to be just specific to your set of circumstances. So thanks.
