The rain hasn't put off the big names and a high-class renewal of the Darley Irish Oaks is in store at the Curragh.
One who is sure to love the testing conditions is Great Heavens, who revelled in the mud when completing a hat-trick with a runaway success in the Lancashire Oaks earlier this month.
John Gosden's representative bids to take the prize back to the UK for the fourth year running, but she faces a strong home challenge headed by Princess Highway, another progressive filly who demolished her Ribblesdale rivals at Royal Ascot.
Aidan O'Brien saddles three of the seven runners and his best chance appears to be Was, who narrowly denied the reopposing Shirocco Star in the English equivalent.
Chief support is the Group Three Kilboy Estate Stakes, in which Caponata attempts to make it three wins from as many starts.
The Dermot Weld-trained filly has barely had to break sweat at Gowran and Naas, but should face a much sterner examination from in-form mud-lover Tannery and Up, who was far from disgraced in the Pretty Polly.
The other Group Three event on the card is the Jebel Ali Stables & Racecourse Anglesey Stakes, and Cristoforo Colombo is sure to be all the rage.
Two fine efforts in defeat at Group Two level followed his debut success, and Count Of Limonade and Grafelli would need to improve markedly on their maiden form to deny Joseph O'Brien's mount.
Katie Walsh and Nina Carberry have strong claims in the Thalgo Ladies Derby Handicap courtesy of Salam Alaykum and Placere respectively, while Paramount will be looking to repeat their success of 12 months ago.
The eight-race card gets under way at 1.40 with the Darley EBF Maiden, in which Dibayani will be fancied to build on his promising debut, while Wonderful and Bendzoldan do battle in the closing Irish Stallion Farms EBF Fillies Handicap.
