One of the first things I learned when I started biking to work is that the ferocity of a hill is relative to the rider. When I started I hadn't biked regularly for about 20 years and my route seemed very hilly to me, but other cyclists told me that it was essentially flat. The worst "hill" was this:

which may or may not be similar to yours. I don't know. I generally went up that hill in a 28x34 gear and stopped at the top to catch my breath. My 11 mile commute took me about an hour. I should mention that I was 40 pounds overweight and an absolute couch potato before I started biking. Some time within the first year (and I think within a few months) I was able to climb all my hills without needing to stop. Within a couple of years I could do the commute in 45 minutes. Now, 5 years later I can ride up that "hill" at 18-20 mph when I want to. I've since moved and my daily commute home looks like this:



And that's if I go up the less steep side of the hill. Coming down that hill in the morning, I can come to a complete stop near the top of the hill and coast up to 37 mph before I hit the stop sign at the bottom of the hill. So going up the hill in the evening I'm back to struggling (with a 30x27 gear), but I'm slowly beginning to adapt.

In summary, hang in there and you'll be riding strong before you know it.
