I did my LT workout yesterday on the treadmill. Originally, because it was heavy rain outside, but also, because the controlled environment appealed to me at this time: I wanted to get some solid indicators if I'm able to run steady 20 minutes at sub-6:30 pace, and how it feels. No distraction from weather, hills, traffic.

It went better than expected. After 20 minutes of warmup at 8:00/mile, I switched the TM to 6:27/mile, and I ran 20 minutes that pace. It wasn't too hard. At no time I felt I was over my LT. I certainly could have done it a lot longer.

I guess this is another indication of a 54 VDOT. I'll do my training accordingly. I will probably need at least 55 to run sub-3 hour in Bowling Green, but I have a lot of time.
