Horse riding and saddlers - recommendations for visitors

[Indiindeed]

My 3 teenage daughters and I are spending some time in the northern Cotswolds in early October. We are after recommendations for places where we could hack out for a few hours in beautiful countryside. Looking for something a bit more than an hour tourist hack as we're all capable riders (have own horses and can easily canter, gallop, jump). We won't have helmets (and possibly not boots) with us so will need somewhere who can provide.

Also looking for good saddlers in similar area for general riding gear including riding wear, horse boots, helmets and back protectors.

Would love some recommendations from real people, rather than trying to gauge a place from a web page.

Thanks
