That’s a good idea…..
The Southern 100 is a proper race with a mass start over the 4.25 mile Billown road circuit at Castletown.
It is Monday-Wednesday evenings for practices and some races plus a full race day on the Thursday….all in a week in mid July. All classes up to 1000cc and sidecars.
It is becoming very popular as the TT has too many long gaps in the day when nothing happens.
It has my vote…..as a local.
