The dates in the currently unpublished calendar are:
7th November - Essex 3Rs
5th December - Stansted Express
16th January - Kelvedon Oyster
13th February - Knights Templar Compasses
Usual 10am start, probably from a car park.
I'm aware that another organiser is offering GPX validation for their calendar rides (and free control towns otherwise), if that's something you wanted to consider for ACME?
That will be Organiser choice to offer per event.
