10 miles is actually a nice commute. It's long enough that you actually get some exercise, not so long that it's really starting to eat into your day. My 13 mile commute takes about 45 minutes on a bike, about 20 minutes in a car, so I figure I'm getting 90 minutes of exercise but it's only "costing" me about 50 minutes (90 - 40 minutes). It's a chance to turn the otherwise worse-than-wasted commute time into something valuable. I also get a lot of audiobooks and podcasts listened to in that time.
