Did my first run for Dec last night - on the treadmill. 4 miles closer to my 100 mile goal (by Jan 8th). I'm at 19/100 so far.

Discovered two things:

1) running on the treadmill with a DVD playing is less boring than running with headphones because I get visual stimulation as well

2) our treadmill is calibrated incorrectly! I've been doing so much running outside that I've gotten really good at telling what RPE gives me what overall pace. As soon as I got on the treadmill last night, it was obviously off. It said it was moving at a 5.0 mph pace, but it FELT much closer to a 5.8 or so. I think the belt moves too fast (the speed of it does shift periodically during a run). Ah well - it is still better than running on busy country roads in the dark anyway. I won't die from a 'too fast' treadmill.

You know...now that I type this, I think I might try a couple more outside runs and then an indoor run on a treadmill at my gym. We'll see if my RPE is as accurate as I think it is (assuming the gym treadmills are correct)!
