Steep technical training vs moderate runnable steeps
I do ultras that are hilly but generally runnable (or at least not super technical/scrambly). I'm fortunate enough to live in an area with lots of different options for hills/mountainsides to train on. I'm trying to figure out which is optimum to use.
There's one particular route that all the "big dogs" do laps on, while other routes are considered inferior. It climbs about 1900' in 1.25 miles, with the lower half being super twisty/technical. I am able to run maybe 5% of it. A light, nimble person with a big stride might be able to run a lot more.
I guess my question is, if the climbs in races are runnable (or at least hikeable at a decent rhythm using poles), am I better off training on similar terrain that allows me to move with a rhythm? Or does steepness trump all? Will I end up stronger for having trained steeper, even if there's not much rhythm to my movements? A lot of fast people around here say go steep or go home, but I'm not sure I agree. Thoughts?
(Yeah, of course a variety is best. Which type of terrain should I be spending *most* of my time on?)
