North West 200: Alastair Seeley dominates first practice

Alastair Seeley posted the fastest times in three of four qualifying sessions in tricky conditions on the opening day of practice at the North West 200.

The Carrickfergus rider was quickest in the Supersport, Superbike and Superstock classes with James Hillier leading the Supertwins times as rain affected first practice in the Northern Ireland road racing event.

Michael and William Dunlop were second and third in the Supersport session.

Final practice takes place on Thursday morning with three races that evening and a five-race programme on Saturday.
