I ran 5 miles on the treadmill las night.  The first mile at 8:something/mile with 1%incline, the next three at 7:53/mile with 1% incline, and the last mile at various speeds and elevations, the last 0.3 miles was somewhere below 6:30/mile.

Essentially, a tempo run. However, I believe my outdoor tempo is faster than my treadmill tempo, and I am unsure if a treadmill tempo run is as effective as an outdoor tempo run.  I'll have  to do some investigating to find out.

Hopefully, I'll be able to get at least 5 more miles in tonight, and again tomorrow, after work.  Which will put me at 22 mi for the week, unless I can get a run in Christmas Eve morning and Christmas day.
