If you’re into epic/epic rock, here’s a few -
Globus Preliator - http://www.youtube.com/watch?v=5q6skxRLnsI
E.S. Posthumus Pompeii - http://www.youtube.com/watch?v=GusLypfx7OQ
Immediate Music A Call to Arms - http://www.youtube.com/watch?v=6_DkftEurYY
Coheed & Cambria Welcome Home - http://www.youtube.com/watch?v=n0H3RlaQVrM (guy sounds like Geddy Lee)
The Ironman Channel on YouTube and Hollywood use a lot of Immediate Music tracks, but they can be difficult to acquire, they only sell to producers, not the general public.
I mix epic scores with rock for my training and pre-race mental conditioning. In addition to some epic stuff, I also currently have Avenged Sevenfold, Skillet, Thousand Foot Krutch, Atreyu, Breaking Benjamin, Muse, Rise Against, Sick Puppies, SOAD and RATM.
