The most likely ground is the Prince of Wales Stadium, which is owned by the council, and currently used by the UG RL team, the Cheltenham Tigers RU club, and an athletics club. It's just about Champ1 standard with plenty of room for improvement. Tigers RU also own a large expanse of lands called Newlands, out of town on the way to the racecourse.
The University own a lot of land in Cheltenham and Gloucester, including The Folly, just down the road from the PoW, where the uni 2nds sometimes play and where the huge schools comp runs. There's nothing there yet, but room for a stadium if that is how they chose to go.
Aside from that, there's Cheltenham Town FC, Gloucester RFU, and potentially Gloucester City FC, with stadia that could stage pro RL.
