Same here. For some reason I don't have the speed in the morning and find myself averaging 14.8 or so but I can average 16.2 on the way home most of the time. My start and end points are about the same elevation above sea level and it's all rolling hills between home and work so I'd estimate about the same amount of climbing both ways. Most of my climbs are about 3-4% but I have one each way that's about 7-8% for about 1/4 mile.
