Triple Olympic champion Usain Bolt will compete in a 150 metre street race in Manchester on 17 May.
The race, which will be Bolt's first in Europe before the World Championships, will be shown on BBC television.
The Jamaican, 22, won gold in the men's 100m and 200m at the Beijing Olympic Games in world record times and also triumphed in the 4x100 relay.
Ethiopia's Haile Gebrselassie will be bidding to regain his Bupa Great Manchester Run title on the same day. Bolt, who will use the event partly as a tune-up for the World Championships in Berlin in August, said: "I am very excited to compete for my first time in Manchester, my first time in a 150m race and my first time in a street race.
"When I heard about the idea I thought it would be great fun and something new and exciting. Hopefully this event will be the start of many more similar events all over the world and inspire kids to take up athletics."
Bolt, a Manchester United fan, added that he had an ulterior motive for racing in the city.
"I am also looking forward to going to Old Trafford to support my team," he said. "I've wanted to come to a match for a long time and am delighted to get the opportunity."
