Hey Leif! Training looks good! How much of your running is off-road? I am always amazed how much slower through the forest I am than my Swedish clubmates; even the ones I can normally run with on the roads/trails.
I run mainly on trail and a little on the roads. In the winter, there is snow off and on, so I am sometimes running in the snow, which seems comparable to forest running. Once I move to a place with conditions more conducive of off trail running I will definitely increase the forest running. Right now, I will look for some new off trail routes to run.
Snow training is always a good leg strengthener!
