Mostly anything by Switchfoot.
I dont know why, but their music just gets me pumped, keeps me going and gets me focused and in the right mindset when I am running (especially long distances). Their music definitely has that tempo that you want to keep when you are running distance.
You should def check some of these songs out by them:
Daylight to Break
We Are One Tonight
Adding to the Noise
Besides those theres one other song that I listen to that really gets me pumped when running. Its called Torre de Babel by Wisin & Yandel ft David Bisbal
