Yes, Usain Bolt will lose an occasional sprint race, but you can count on him to bounce back strongly following those defeats, as he did at Oslo's Bislett Games last Thursday.

Other meet highlights included Meseret Defar's 5000-meter victory in a world-leading 14:26.90. Rising steeplechase star Conseslus Kipruto of Kenya, the 2012 World Junior champion, won his race in 8:04.48, while Caterine Ibarguen leaped 14.81 meters (48 feet, 7 inches) to beat triple jump rival Olha Saladuha (14.56/47-9¼).

Ayanieh Souleiman of Djibouti won Oslo's Dream Mile, traditionally one of the world's premier mile runs, in 3:50.53, to edge Kenya's Nixon Chepseba (3:50.95). Check out the full results from the Oslo meet.
