The Prefontaine Classic will provide an early look at World Track and Field Championships contenders, live on NBC, NBCSN and NBC Sports Live Extra on Saturday.
The annual Diamond League meet in Eugene, Ore., will carry extra significance this year, given it will be contested on the 40-year anniversary of the death of its namesake, 1972 Olympic 5000m runner Steve Prefontaine.
Competition starts Friday night, with Olympic and World champion Brittney Reese in the long jump, Olympic bronze medalist Reese Hoffa in the shot put, Bernard Lagat and Galen Rupp in the 5000m and Olympic and World champion Mo Farah in the 10,000m.
