Nature Strip, the world’s top-rated sprinter, is on course for a mouth-watering clash with American raider Golden Pal in the King’s Stand Stakes on Tuesday, while Home Affairs runs over a furlong further in Saturday’s Platinum Jubilee Stakes.
Galloping individually over four furlongs, they stretched out having been restricted to canters since their trip over.
Compatriot Artorius, from Anthony and Sam Freedman’s operation, also worked ahead of his run in the Platinum Jubilee Stakes.
Waller's only previous runner at the royal meeting, Brazen Beau, took second place in the 2015 renewal.
After a trip totalling around 40 hours, with stopovers in Singapore and Dubai, connections are pleased with their condition in the build-up to next week.
Waller is not underestimating the opposition, which includes American 'banker' Golden Pal.
