Mo Farah has promised "a great show" when he takes on Ethiopian legends Kenenisa Bekele and Haile Gebrselassie in Sunday's Great North Run.
The trio, who have 12 world titles and seven Olympic golds between them, will compete over the half marathon course between Newcastle and South Shields.
"I've got the track speed but it all depends on how the race goes," said Farah, now focusing on marathons.
"The most important thing is not about time, it's putting on a great show."
Farah, 30, became only the second man after Bekele to win both with his double distance success in Moscow earlier this year.
Three-time Olympic champion Bekele, 31, is making his competitive half-marathon debut on Sunday, and Gebrselassie has recorded by far the quickest time over the distance of the three men.
The 40-year-old set his best time of 58 minutes 55 seconds - the 11th fastest in history, and nearly a minute and a half inside Farah's best - in Phoenix, Arizona in 2006.
He also won the Great North Run of 2010.
"It's a unique race this weekend, and everybody wants to see a wonderful moment," said the Olympic 10,000m champion from Atlanta and Sydney.
"I am well prepared and on Sunday we will see."
Farah was due to take part in last year's race but pulled out after the birth of his twin daughters disrupted his training.
The Somali-born Londoner will focus on road running next year,
And his coach Alberto Salazar has suggested Farah may compete in the marathon at the Rio Games in 2016 rather than defend the track titles he won at London 2012.
Last year's winner of the women's race, Tirunesh Dibaba, returns after winning world 10,000m gold at Moscow.
Her main opposition will come from fellow Ethiopian Meseret Defar, the reigning world and Olympic champion over 5,000m.
The elite athletes will be joined by 56,000 amateurs in Britain's biggest participation race.
On Saturday, a high-class field takes to the streets of Newcastle and Gateshead to compete in the Great CityGames.
Britain's world 400m champion moves down in distance to compete in the 150m, while James Dasaolu, Dwain Chambers and Harry Aikines-Arteetey make up the home contingent in the men's 100m.
Hannah England, Jenny Meadows and Eilish McColgan (mile), William Sharman and Tiffany Porter (110m hurdles), and Chris Tomlinson (triple jump) are among the other Britons competing.
