It kinda depends on just what kind of time you are shooting for in that marathon... The stuff that you're listening to, though upbeat, ain't got much "kick" to them... No offense...

See, if I were going to run a marathon I'd shoot for a little quicker a pace and throw in some:

AC/DC
Spooky Tooth
Jethro Tull
Metallica
Poison
Ten Years After
Led Zepplin
The Kinks
Cream
Bon Jovi
more "Black Crows"
Mississippi Fred McDowell
Jessie Mae Hemphill

Yeah, them folks get that marathon time down a few minutes...
