David Carr: is it time for Ascot hero Alan King to focus on the Flat?

Here is a question that might stump even those who have spent the whole of lockdown quizzing like Richard Osman's brainier brother. Of all Britain's top-level courses, where has last week's six-time Royal Ascot winner Jim Crowley shown the greatest level-stakes profit?

Well done if you knew that a punter would have made £63 if they had put £1 on all his mounts at Aintree, thanks largely to a 50-1 success on Uncle Bert for Lucinda Russell in October 2000.

That is not brought up just in an attempt to floor eggheads but as a reminder that the 2016 champion jockey, who was beaten only on countback for the title of top rider at Ascot, is very much a product of the jumping world.
