Yeah it is. I've just done some research as well. Stanghow is ranked 138 in the list for the Ayr Gold Cup. At first that makes me think he has no chance of running in any of these Cups, but after looking at previous renewals, he would definitely get in The Bronze, probably carry top weight there, but he may actually sneak in off a light weight in The Silver Cup, so it could be either. Oh its so exciting this isn't it - waiting for a horse you actually rate to run in a nice handicap!
The only fear is it coming up soft ground. He's a good ground horse on all known form, so anything softer than Gd/St would balls his chance right up.
