Crunching the Numbers

After running for four months with my Garmin 305, I finally installed the device's software and uploaded a season's worth of runs onto my computer.

One thing I've realized: I usually don't wait long enough for the satellites to pick up my Garmin before I start running. I'm not exactly a patient person, alas. Garmin doesn't start tracking my run until after I've already logged a half-mile. Which means that Garmin undertracks my mileage.That also means that the first mile of my runs read abnormally slow: 13 to 14:00/mile instead of 9:30/mile or so.

Does this happen to anyone else?
