Sand, have you tried listening to an audio book on slower runs? Better than music on a slower pace
Can't do those while running. I don't pay good enough attention to really catch anything (I've tried). A lot of times I'll have music on random and not have a clue when I'm done what played.
Not knowing what you usually listen to, try slower music.
My usual play list includes stuff like Disturbed, Papa Roach, Drowning Pool, Stone Sour, Sevendust,Tool, Slipknot, etc.
When I go out on slower runs it's a totally different playlist - Oasis, Coldplay, Dave Matthews, John Mayer, Muse, Vitamin String Quartet, etc.
Like you, I find it very difficult to focus on longer + slower runs, so I set my music to make it more natural to just go nice and easy.
