Early in a training program, the discomfort of not being in shape and/or weighing too much makes most every run unpleasant. Slowly progress is made and there is the OCCASIONAL run that feels good. Sometimes it comes when it is unexpected: like this morning. Seven miles, clipping along nicely, no adverse effects from the previous day. I like that.
Looking forward to more. By the way, halfway through the year and at 970 miles. After a poor beginning, 2300-2400 seems doable.
Keep on moving!
