7 mile mid-week long run

Seven miles in 1:34:02 (13:26 pace) along the Kingwood greenbelts. The first mile was tough, but I quickly settled into a rhythm. The weather was a negative factor. Hot and humid. Sporadic sharp left knee pain when I walked. My regimen today was run-10/walk-5. I'll continue this for the next two weeks, when the mileage is over 5 miles.
