Rainbow Peak is heading for Royal Ascot following his encouraging recent seasonal debut.
The Wolferton Handicap Stakes, a Listed contest over a mile and a quarter on June 18, is the objective for the Peter Savill-owned four-year-old.
"He runs in the Wolferton at Royal Ascot. He's been kept for that," said trainer Michael Jarvis.
Rainbow Peak was unraced as a juvenile then won all his three starts at three before going down by a head to Fareer in a hot handicap over a mile at York on his return earlier this month.
Meanwhile, Sajjhaa is to leap straight from maiden company to the highest level by taking her chance in the Investec Oaks at Epsom on Friday.
The filly, trained by Michael Jarvis, was slashed in price from 16-1 to a general 8-1 after she was left in the Classic at Saturday's confirmation stage.
"She's in great order and I think she will run," said Jarvis.
"When it gets close to confirmation time you'd be daft to have a bet, so I suppose people were waiting to see whether she was confirmed or not first.
"They only have one year to have a crack at the Classics so if you feel they are good enough they deserve the opportunity."
Sajjhaa, who carries the colours of Sheikh Ahmed Al Maktoum, only made her racecourse debut earlier this month but she could not have been more impressive in beating Saggiatore by seven lengths at Sandown.
Frankie Dettori was in the saddle that day but there are two other fillies he could ride - Godolphin's Hibaayeb or the Mark Johnston-trained Marie De Medici - should they get the go-ahead to run.
"There's no decision on whether Frankie rides. The policy is that Frankie is offered the horses to ride in the Darley set up and it obviously depends on what the others run," Jarvis explained.
