Wednesday's racing was cancelled due to adverse conditions, so Ryan's next race came in Thursday's Supersport 600cc race where he was again embroiled in a terrific battle for the lead. Ryan, Lougher and Cummins were together throughout the 8 laps with the lead exchanging hands on countless occasions. He overtook Lougher each time at the final Castletown Corner but the superior acceleration of Lougher's machine saw him back in the lead by the time they reached the finish line and this was how it unfolded on the final lap. Ryan took another runner-up spot, missing out on the win by just 0.268 seconds although he did have the consolation of setting the fastest lap of the race at 106.534 mph.
