KINGSTON, Jamaica (AP) Usain Bolt spent a few minutes on the grassy infield of National Stadium after his race Thursday night, putting himself through some very slow cool-down jogs.
It was an easy end to an easy night.
Officially beginning his quest for a third consecutive Olympic gold medal in the 100-meter dash, Bolt cruised through the quarterfinals at the Jamaica National Senior Championships - which serve as his country's trials to decide who goes to the Rio Games in August.
No one has ever won three golds in the 100, which is what both Bolt and Shelly-Ann Fraser-Pryce could do in Rio. They'll be among the favorites to qualify for the team on Friday night, when the 100 semifinals and finals are held about two hours apart for both the men and women.
Bolt completed his quarterfinal in a jog-for-him time of 10.15 seconds. Fraser-Pryce won her quarterfinal in 11.38 seconds.
