2013-12-24 - Eight Parking Garage Stair Repeats

~1.7 miles @ ~15 min/mi

Stars twinkle overhead; the temperature has fallen now to near freezing after the past few days of silly warmth. Kristin leads on the odd-number repeats and I go first on the even-numbered ones, as we descend the eastern staircase and climb the western side 8 times. GPS signal shadows and reflections make for wacky maps.http://zhurnaly.com/images/running/Garmin_GPS_stairwork_map_2013-12-24.png
The Garmin is far more consistent on elevation measurement, with its barometric sensor, than the iPhone Runtastic using only GPS.http://zhurnaly.com/images/running/Garmin_elevation_stairwork_2013-12-24.png
