While I'm on the subject of 100s. Here is another. It was previously half DC on the A1 and half on other slower roads.
A revised course is being used and it is apparently now about 80 to 90 miles of DC all based around the A1.
It's the week before the SCCU 100, so good training.
I've entered already
George this could be for you after the ECCA 100 was cancelled.
