Running over a trip slightly short of her best, Saeed bin Suroor's five-year-old was briefly outpaced as Mick Halford's Rehana was given an easy time of things at the head of affairs.
With two furlongs to run, Pat Smullen was still sat motionless on the Aga Khan's filly but eventually Promising Run began to wear her down under Pat Cosgrave.
Deep inside the final furlong, Promising Run pulled clear and ended up being impressive.
Bin Suroor, who trained Cape Verdi to win the 1000 Guineas at Newmarket 20 years ago, said: "The pace wasn't fast and I told him to sit handy as she stays further.
"The second is a nice filly and ours was a Group Three winner as a juvenile. She'll go for the Balanchine next."
Gold Town made every yard of the running and turned the first division of the UAE 2000 Guineas Trial into a procession.
William Buick was keen to grab the rail on Charlie Appleby's son of Dubai World Cup winner Street Cry and wound up the pace from halfway.
He was able to get a breather on the turn for home before stepping on the gas and stretching well clear.
Having attained a decent level of form on turf, being by a dirt performer it was no surprise to see him reach another level on this surface.
John Ryan's Roland Rocks finished a fine second considering his last run was over five furlongs in the Flying Childers at Doncaster behind Heartache.
"It was a great performance, if you can get on the lead and get them in a rhythm over that distance it's a big bonus," said Buick.
"He won very well. He's by Street Cry, which is a huge bonus on this surface, and he's an exciting horse to look forward to."
Godolphin were also on the mark with Bin Suroor's Don't Give Up, who won the opening 10-furlong handicap, and he bookended the meeting when Mountain Hunter was steered to perfection by Christophe Soumillon from gate 14 in the last.
The second division of the 2000 Guinas Trial went to Luke Morris on the Fawzi Nass-trained El Chapo in a driving finish from Bin Suroor's Racing Country.
El Chapo won twice at Catterick for Richard Fahey before being sold for £58,000 and had to be determined to grind down the Godolphin runner.
Richard Hannon's Tangled was well fancied but missed the break and trailed in last on his dirt debut.
