The "A" qualifying standard for men's 1500m at 2003 World Champs in 3:34.90. The qualifying period began January 1, 2002.
According to Athletics 2003, a total of 24 runners met the "A" standard in 2002. One of them - David Krummenacker - definitely won't be running the 1500 in Paris, and if I counted correctly 10 of the 24 were Kenyans, so that's another seven that won't compete in that event. So far in 2003, four more runners have run sub 3:34.90 - five if you can count an indoor 3:34.66 - but a couple of them are new Kenyans. So with 3 runners per country and the inevitable no shows because of injury or whatever, you might be able to run the Paris 1500 as a straight final. Of course some countries - can we say USA? - will enter only one runner with a "B" standard so there will be other rounds but they'll be pretty thin.
