After a delay due to rain followed by a number of red flag incidents, the 2018 KDM Cookstown 100 was abandoned with a number of races still to be run.
The 17-race programme started with the invitation Supersport race which was carried over from Friday night, Derek Sheils led the opening laps closely followed by Adam McLean and Michael Dunlop. Dunlop took a couple of laps to make his way to the front a lead he held taking the flag 2.8s in front of McLean. Team-mate James Cowton passed Sheils in the closing stages to nab the 3rd step on the podium.
Just before the first Superbike race started there was a sharp rain shower the organisers decided to delay proceedings until the circuit was dry.
With the sun shining the race got under way, this time it was Michael Sweeney who led off the line followed by Derek McGee, Adam Mclean, Brian McCormack and Michael Dunlop, as Derek Sheils only qualified 12th quickest he started in the second wave of riders.
As the front four fought for position, Sheils with a clear road in front of him soon made up time, Dunlop eventually picked his way to the front of the leading group and at the flag led on the road but Sheils had cut the deficit by enough to take the win on corrected time. Dunlop was second and Sweeney third.
The second Supersport race was a one-two for local team McAdoo, James Cowton took the win from Adam McLean with Derek Sheils in third after the race was declared after a red flag incident.
Derek McGee, Adam McLean and Paul Robinson respectively were the top three in the 125/Moto 3 race.
McLean also won the Supertwin race ahead of Kiwi Dan Mettam a newcomer to Irish road racing and Davy Todd. It was during the supertwin race that the rain started again causing a number of red flags. An oil spill when four riders went down at Braeside corner caused yet another substantial delay.
Pushed for time the laps were cut in each race, but another two crashes at Braeside in the Senior Support race the clerk of the course decided to pull the plug and the meeting was abandioned with a number of races still to be run, including the feature Cookstown 100 Superbike race.
