Trainer Warren Greatrex has given Keeper Hill the go-ahead to run in the Neptune Investment Management Novices' Hurdle at the Cheltenham Festival.The six-year-old has won his last three races in the manner of a most progressive horse and will now step into Grade One company on Wednesday. Greatrex said: "He runs in the Neptune. "We looked at the race and the horse has improved a lot since his run at Huntingdon. I think he deserves his chance. "If he puts it altogether in the race he will put in a good performance. I don't think we have seen the best of him yet."He has schooled well and his work has been brilliant."
