Over this summer, I've been training to run a marathon and am just about to reach the milestone of half-marathon, and I'm pleased as punch about it. Only problem is, I reach mental exhaustion before physical exhaustion, sort of tired -of- running instead of tired -from- running. One way that keeps me from losing focus is rotating around a few playlists that work for me (right now it's a variety of Dropkick Murphys, Miracle of Sound, the Outlaws, and Queen) but I'm interested to hear what works for the Escapists' running community. Any good jams that I should think about adding to my playlist?
