That wouldn't be enough for me - I need more variety. Both in variations in distances but also routes and scenery.

Today I was ready for a 40 mile ride and though there are several 40 mile loops I can do from my driveway, there just wasn't anything that suited my mood. So I drove to a western suburb where I knew I could park near a good bike route and then rode further west. The first 10 miles was a familiar route, but then I rode past my mental map to new territory. I ended up in a nature preserve that has paved bike trails (an accident, I didn't know it was there) and turned east in the general direction of the car after 20 miles. Adventure!
