What makes Newmarket's G1 Darley July Cup one of the truly great races in the British Racing calendar is that it is a big sprint run on the perfect sprint track.
You will not find a better test of the fastest horses of each generation.
Obviously, speed is an essential ingredient, but so, too, is a certain amount of stamina, as the uphill climb to the finish provides the most important part of the test.
Godolphin's budding sprint star Harry Angel has all the attributes to join an illustrious group of horses, who have triumphed in this rigorous six-furlong examination that, for so many, leads to a career at stud.
Consider these names of the past three decades: Green Desert (1986), Cadeaux Genereux (1989), Royal Academy (1990), Anabaa (1996), Oasis Dream (2003) and Starspangledbanner (2010), all of whom have left their mark as stallions as well as racehorses.
The Clive Cox-trained Harry Angel, who would readily fit the profile, will be out to avenge his defeat by Caravaggio in the G1 Commonwealth Cup at Royal Ascot, reckoned by many to be the race of the entire Royal meeting last month.
The pace factor (who actually makes it) and the draw are both going to influence the result.
Jockey Adam Kirby has allowed Harry Angel to use his tremendous early speed at his last two starts, when breaking a track record in the G2 Sandy Lane Stakes at Haydock and when second in the Commonwealth at Ascot.
This time, Caravaggio and Harry Angel are drawn wider apart than at Ascot, which may relieve the early pressure on the Godolphin sprinter, thus allowing him conserve a little for the final kick for home up the hill.
The Tin Man has a very strong finish and will be ideally suited by the track, while last year's winner Limato is reunited with Harry Bentley and could be coming with a late rattle when they hit the rising ground. Tasleet is another major chance.
On a busy weekend of international racing, this year's Darley July Cup at Newmarket stands out as the major attraction. Don't miss it.
