Michael, good for you to keep going with moist feet - seems like you've gotten thus far by not finding excuses.
Today I got in 4.25 miles in 40 minutes - that included a cool down period, achieved 5K in about 29 minutes. The treadmill I was on had an absolutely unreliable heart rate device, when I stepped on it said 198 - when I had finished my first mile it said 88, I found it amusing.
I walked into the locker room after a great stretch and thought "I don't know if I've ever been happier".
But now, I work!
