There seems to be no shortage of places to ride in Spokane. For a nice ride from downtown, take the Centenial Trail west through Riverside State Park. Taking the CT east brings you through more residential areas until you get to the state line. If you take the trail west, it'll be through parkland, and you could even continue on the country roads after the CT ends, if you want more miles. From downtown to the west end of the CT trail is about 12? miles. There are some nice country roads north and west of town if you'd like to bring your bike by car to the starting point. If you're into mountain biking, you could also ride right out of downtown to Riverside State Park. There are many more places too, if you want more info PM me.
