Funny. I only have one practice session a day, but I practice for as long as I have time for. My fingers don't get tired or sore from practicing for several hours, unless I'm doing palm muting or trills at full speed. Then it starts to hurt a bit... If I practice, take a 15 minute break and then pick up the guitar again and continue to practice, that's when the fingertips start to hurt like hell...
