My husband and I are driving from the PacNW to the Tucson (Oro Valley) area with our 10year old 40-lb dog who takes daily 2-3mi walks, and two road bikes for a 10-day stay in early January.  We are moderate day-hikers and cyclists, given our fitness levels are low at this time of year due to the bad weather severely limiting availability here.

We'd appreciate people's suggestions concerning 8-mile or less day hikes (preferably allowing dogs) and <30mile cycling routes.  We've hiked some of Sabino Canyon and Catalina State Park last April while there.  Also, we did the whole 100 mile Bike Path Loop in 2 days last April, but we were in much better cycling shape than we are currently.

If there are any other "can't miss" ideas to see/do while there (i.e. like the Franklin Car Museum we saw), I'd really appreciate the suggestions.
