Human Factors
Unexpected last minute change of runway from RNAV Runway 29R to ILS runway 11L. Winds were calm forecast to pick up out of the west at our arrival time. No digital ATIS; didn't find active runway until listening to ATIS on radio well into the arrival. On downwind vectors advised of pair of military aircraft we would follow on approach. Turned base and cleared for visual approach to Runway 11L. As we turned in towards the airport; we crossed a knoll just north of the final approach course. We were descending and crossed over the top of the knoll at about 1;400 feet AGL. The GPWS activated and announced pull up terrain; the FO (First Officer) executed an escape maneuver as he had been trained.  With autopilot off speed quickly accelerated and still in the flaps 2 configuration we exceeded the limit speed by about 5 knots for 5 to 10 seconds before speed reduced back into normal range. We advised TUS that we were missed approach and were vectored around to another visual approach and landing.Cause - Higher than normal workload; changing runways; keeping traffic in sight and terrain awareness.On calm wind days be prepared for approach from either direction on smaller airports with only one primary runway. Study terrain areas to plan for visual approach altitude you want to be at crossing them.
Air carrier flight crew reported GPWS Alert on approach to TUS airport.
