Do you mean three quarters of a mile away or 3 to 4 miles away? Map link doesn't work so not sure.
Last year the traffic jam almost reached back to Swindon big queues onnthe A419 both ways and from elsewhere. Almost everywhere close by is no parking without permits (some no access) as they try and filter you into Fairford from quite a distance away now. You could try using the old A417 from Cirencester to Lechlade and Fairford and stopping in one of the villages on the way and cycling the rest.
