Nicky Henderson expressed his delight after Brain Power, Peace And Co and Josses Hill took part in a racecourse workout at Kempton.The trio were in action for just over a circuit of the Sunbury venue, with Josses Hill taking them round before Champion Hurdle contender Brain Power went on a furlong and a half out, followed by Peace And Co.That is how they finished, and Brain Power's rider David Mullins said: "He felt very good, we all came up on the bridle and it feels like he's in great form. Hopefully he will stay going the way it is."He added: "He is an improving horse and I can't wait to be on him at Cheltenham."Peace and Co, who could head for the Imperial Cup at Sandown, which would set up a potential bonus bid at Cheltenham, was partnered by Jerry McGrath, who said: "That will have done him the world of good, getting him in the paddock nice and relaxed, and he settled very well."There's still a big pot in him. To be fair they have spent a lot of time at home getting him to settle and relax, as he showed today. He really has switched off. This time last year he would have run away with you, but this year he is more amenable."Henderson said: "That was good, and exactly what I wanted and hoped for. Josses Hill was great, you can see why he wants that bit further."Brain Power was great, he was tanking throughout and he loved it. David said that's the way he wanted him to go."You saw a different horse today with Peace And Co. This time last year he would have been a hundred yards in front before the winning post the first time round. That's his first anything, but we've been doing lots of work at home."We might be looking at the Imperial Cup and things like that."
