Great information! It raises so many questions for me. For example, I have been road running now for 4 years and I am doing roughly 100km/week. If I want to get into trail running, should I target a specific volume of vertical climb per week? Do you think it is necessary to do some specific ankle strengthening exercises? Also, while running 6 days/week, how do you decide which day to do strength training?
Great question! In my personal opinion if I might... the vertical training that you'll aim will be 100% to the kind of race you are doing that season ...
