  We consider the coupling of racetrack inflation to matter fields as realised
in the D3/D7 brane system. In particular, we investigate the possibility of
cosmic string formation in this system. We find that string formation before or
at the onset of racetrack inflation is possible, but they are then inflated
away. Furthermore, string formation at the end of inflation is prevented by the
presence of the moduli sector. As a consequence, no strings survive racetrack
inflation.
