I just got back into running myself after a taking a year hiatus... and now I'm training for a 1/2 marathon in December.. it's been a great way to focus on myself and not think about the chaos at home..
Since my running goals are ones that are positive ones, I have only loaded up songs on my ipod that are fun and motivating.. songs about drugs will only remind me of what I'm "running" from if that makes since...
I have songs like Born to Run, Eye of the tiger, life is a highway, devil went down to Georgia, welcome to the jungle.. things like that...
