The smallest route I typically go on since moving to The Bay Area is about 25mi and 1,150 ft. I have a handful of routes between 30-35mi that are around 1,800 ft, and those are my most common, allowing me to get about 100 mi a week and 5k ft of climbing in over 3 rides, excluding errands and such.

Yesterday was a big one at 40mi and 3,400 ft
