Narrative:

Takeoff without V speeds for the runway in use. The airport has no taxiway and when you land or take off you shut down the airport while you are on the runway. During arrival; ground operations; call for clearance and taxi the controllers were very difficult to understand and all transmissions had to be repeated 2-3 times until understood. I understand a nearby sector's controllers better. We arrived using runway xx and since the winds were calm and the weather clear; we set up for a runway xx departure. After push with the engines running we performed all checklist items on the ramp prior to taxi to expedite our departure and minimize our time on the runway.we taxied from the ramp to the hold short position and at that point we discovered the runway changed to xy departures. (I did not understand that the active runway had changed when we picked up the ATIS from ground.) ATC clearance was not given until after we taxied out. I was heads up taxiing the aircraft while the first officer went heads down to reset the FMGC and pull up the new numbers. We had a long taxi and I did not feel rushed as we reached the end of the runway for our 180 turn to line up. As we lined up with the runway the first officer took control and pushed the power up for a rolling takeoff. At 80K we got an ECAM warning that the numbers were missing. We both realized what had happened at the same instance. The numbers for runway xx were still posted via hard copy on the panel between us and since we were past 80K and accelerating on a flat sea level runway with no obstacles we continued the takeoff using the V speeds for runway xx. The takeoff was uneventful and the rest of the flight proceeded normally. I've kicked myself a hundred times since this happened. I know better. Whenever something changes; like the active runway; I should have called for a compete reread of the checklist and the mini brief. That would have prevented this from happening. I asked the first officer if he got us turned around but I was heads up and I did not check before the power came up. He did get the new runway in the FMGC but missed getting the V speeds and I had not checked. Although there were no external forces pushing me to expedite I did feel an internal obligation to minimize our use of the runway due to local conditions.

Title: An A319 flight crew failed to recompute their takeoff speeds when the airport reversed directions from their single runway. The continued the takeoff utilizing the data for the opposite direction rather than rejecting the takeoff at high speed.
