My legs were tired and both my anterior calf muscles got tight on me. This is the first time I've run with my garmin and it says I was .2 a mile short on my run so I kept running to 3. But the map on this says the route is 2.96 and when I drove it in my car it was 3. Since it was cloudy and rainy today I wonder if that messed with the satellite. I'll see next week when I run 3.
