I've made our guys aware of the time period, at the moment I'd like to pencil in Saturday 9th Sep.

As far as race length, our default is 3 minutes depending on the numbers of club members that turn up, for Saloons that'll be 27 laps for the quickest cars.

I think mostly hosts will be working between 2-3 minutes car run time, some will run 2 lanes for each car  with 2 cars together for shorter time on each lane. For me having a 2 lane track it it is better for me to run just one lane for longer.
This is a points championship, so it is the placings of the cars at the end of each Round which matters most, the measurement used to achieve that could be overall run times or distance. Fastest laps can be recorded as a position determining measurement in the event of a “ position tie”
