re: your blog comment
What I am saying is that speed workouts aren't a necessity but they will provide performance gains. That said, with the increase of speed work comes the increase chance of injury.
Running injuries don't necessarily show up the moment they happen.
The bottom line is I've never hurt myself running slow. I'm not trying to discourage speed work, I just think one needs to build up to consistent frequency and that takes time.
Length before strength and strength before speed. Go long, add force (hills), then go fast.
Good point. Could have done it on the hill workout earlier in the week though I do honestly believe that it was the very steep downhill that i stupidly chose to run on my route.
