The colt is trained by Simon and Ed Crisford at their Newmarket yard, which has already sent out 78 winners this season. That's a yard firing on all cylinders, one with the know-how to get a first-timer ready and the experience to spot what a horse can do. For a debut runner, that counts for something. But until Shimmering Shadow actually races, there is nothing to judge except the hope that comes with good breeding and a competent stable.
