I didn't run today for two reasons:
1) I had a sad family event that distracted me
2) I woke up this morning with very sore knees. I think running on the treadmill did something to me.
In any event, I still will get my 3X this week, but I was trying to do 4. Today has sucked and I probably could have used a good run.
Hopefully, the rest of this week will go better.
