The Cookstown 100, which traditionally kicks off the cobwebs of winter on the 2.1 mile Orritor circuit in County Tyrone, is set to run on April 24 and 25.
Just a week later, action moves up the road to the Tandragee 100 just outside of Portadown on May 1 and 2 in final reparation for the opening international of the year – the North West 200.
Triangle circuit action is set to kick off on Tuesday May 12, ahead of final qualifying on Thursday morning, the first of the races on Thursday evening and the feature race day on Saturday May 16 with a full schedule of Superbike, Superstock, Supersport and Supertwin races on tap.
A fortnight later riders head across the Irish Sea for practice week for the Isle of Man TT, provisionally set to begin on Sunday May 31 ahead of race week, which start with the traditional opener – the Superbike TT – on Sunday June 6.
After only running for the past two years, it is understood that the Enniskillen Road Races will not be held in June 2020, nor will the Mid Antrim 150 which will once again be off the calendar.
But there will be six back-to-back rounds starting in mid-June with Kells, Cork, Skerries, Walderstown and Faugheen Road Races all running on consecutive weekends starting June 20 and 21.
Following the Isle of Man Southern 100 Road Races from July 6-9, the National circus heads back to Armoy for the Race of Legends on July 24 and 25 .
The East Coast Festival will run at Killalane on August 8 and 9, and without an Ulster Grand Prix date confirmed, rumours abound that it could run the following week – if at all.
