Is it correct that a private estate which has bridleways passing through it as marked on an OS map refuse cyclists to enter whilst allowing horse riders?
The estate in question is the Bathurst Estate, Cirencester, Gloucestershire.

I'm new to the area and was very politely asked to leave the estate as I'd wandered near the polo grounds but other areas such as the Macmillan bridleway sections also have the Bathurst Estate signs erected stating no cyclists.
