Long-ish mountain bike ride today...

So I decided to take the day off today and go for a mountain bike ride. Initially I planned on just out and back from my house to the top of the Millcreek Pipeline tail. When I got to the top I decided to keep going up the canyon and then rode up to Dog Lake. From there I rode Big Water to Mill D North Fork, and then down Big Cottonwood Canyon and back to my house. I think it was between 30-32 miles total. Not too bad, I never really stopped other than to eat. Overall it took me about 4.5 hours, overall almost 7 miles an hour. I'd like to get to where I could average 10. I felt pretty weak today in comparison to how I felt earlier this week, so I think that a 10 MPH average is doable.
