Today was my last training run before Saturday's Celtic Solstice 5-miler. Went out and did 4.1 miles in darkness, before our snow today (1-2 inches...mid-westerners, promise not to laugh!). At 2.5 miles, my Sony's battery died, and I ran the rest of the way listening only to my own labored breathing and the slap-slap-slap of my big duck feet on the pavement.
