A bit of description of your route profile. About 17 miles. The Trinity River is about halfway through the ride with a climb of about 700 ft in each direction (yes, uphill, both ways)

Most of the route is through residential neighborhoods. A little bit on a MUP, a few blocks of multi-lane highways, and a couple miles of rural two-lane.
What kind of bike you ride.
Primary bike is a 1994 Nishiki Sport XRS
Backup bike is a 1973 Schwinn Varsity
How you carry your gear and what or how much (volume) stuff you bring on the ride.
Change of clothes, towel, toiletries, lunch, repair stuff. Carry it in panniers on the Nishiki or in the baskets on the Varsity.
Distance & time (average speed if you care to share)
Takes me anywhere from about 1:05 to 1:30 to ride the 17 miles each way The biggest factor is the headwind which is usually on my way home.
