KGV Field Usage

It appears horses are being taken into the KGV Field on Crick Bridle road. Please note that this field has specific guidelines to its usage in the deeds and horses are not permitted in the playing field. The horses(s) has left deep hoof print holes in the soft surface which could be a dangerous trip hazard for people and dogs that may be running around in there. Such holes can also cause damage to mowing equipment.
Motorbikes have also been using the playing field. Please note that this is also not permitted, again, an activity that could be dangerous to other users of the field.
Can we politely request that the field is only used for its intended purposes such as walking and ball games.
