I've always considered 8 hours as "the goal". Ran a 8:10 back in August of 2010, moved away for a while, then moved back to the mountains and was able to focus on the TCT again. Finally got it under 8 hours. Barely. I think I've got a 7:45 in me by the end of the summer. I'm sure someone else out there has sub-7 potential...
