Sunday Long Run (12 miles @ 9:28 min/mi)

Due to yesterday's snow I did this run on the basement treadmill. I was supposed to do an easy pace for 10 miles then speed up to my 10K pace for the last two. I attempted the speed up during mile 10 running at an 8.4 MPH (7:08 min/mi) pace for a half mile when my treadmill flipped the time counter and the belt stopped (exceeded 99:59). I reset the program and kept running, but lost the will to go fast - it was hard enough to psych myself up to run fast when I was tired, much less after I've had to do an abrupt stop.
