I used my new Garmin Forerunner 101 GPS for the first time this morning. I checked the distance of my "6" mile course. The course is actually about 6 1/2 miles. No wonder I was so tired earlier this week. I had added about 20% instead of 10% to my run. I stopped today after 6 miles and felt pretty good.
The temperature was about 45F when I left. A strong 10-15 mph wind was blowing. It was hard to go South into the wind but was great when going North to have that tail wind. My wakeup HR was 50.
