Every morning I climb a pretty major hill on my way to work where my average speed is between 5 and 8mph for about 2 miles. What is the safest thing to do when traveling at such low speeds? The sidewalk is poorly maintained, so that's out of the question. I would feel guilty riding in the lane and forcing rush hour traffic to go 5mph while I huff my way up the hill. Usually I just ride to the extreme right (in the door zone actually) and then merge left when I need to turn. Merging into the lane makes me nervous every morning and I'd like to find a way to safely avoid it. Any thoughts?
