I have been looking for ways to extend my route. Mostly because I think to hit my goal I'm going to need to do nearly a hundred miles a week, and my standard commute, assuming I ride all five days of the week, only provides 75 miles.
I added a mile to my ride home yesterday changing the route. I actually think there's more climbing, but it's a lot less rolling hills, which makes it a lot more enjoyable, and faster. Then again it could have just been the heat and my desire to get out of it as quickly as possible.
