Oxford Kidlington EGTK

So, I was just at EGTK, but I was very confused because I didn’t find a taxiway to runway 19. So I checked it at a chart and saw that there is no taxiway to runway 19. Should I hold Short then at RW 29 and ask for take-off, so TWR can tell me to back-taxi or what should I do?

Yes, Tower shall instruct you to Back Taxi.
