When the gods tap you on the shoulder, it's wise to take notice.
There's only one Proclaimer in the 4.10 at Ayr, so it's logical to assume that we should be looking for a trip of 250 miles rather than 500. A quick check with the AA guide shows that the distance from Julie Camacho's Star Cottage stables to Ayr Racecourse is exactly 250.4 miles. That's via the M6, of course, and I'm sure that pedants in the audience will point out that you aren't allowed to 'walk' on a motorway.
Moving from divine guidance to logic, his last run rather petered out because he didn't look fully fit and Haydock appeared to be particularly testing that day. He didn't take up an entry on Monday (not soft enough), and I think today's ground should suit him very well. As I've said elsewhere, this season's 3yo ratings are very much a matter of opinion, and I've no idea whether he's well treated here or not. But on the assumption that Julie wouldn't send him this far to have a (probably) hard race without good reason, the 7-2 currently available doesn't seem too miserly.
