Usain Bolt begins his farewell meet — the world championships — live on The Olympic Channel: Home of Team USA and streaming here on and the NBC Sports app on Friday at 1:30 p.m. ET.

Bolt, in the last individual event of his career, gets started with the 100m first round at London’s Olympic Stadium. He will race between 3:20 and 4:15 p.m. ET.

Bolt and top rivals Justin GatlinChristian Coleman and Yohan Blake will be among the heats, with 24 men advancing to Saturday’s semifinals if the same format is used as in 2015. The final is also on Saturday (NBC and streaming, 3 p.m. ET).

The lone medal event to open the 10-day meet is the men’s 10,000m (4:20 ET), where Brit Mo Farah will look to win a third straight world title in the 25-lap race. Like Bolt, Farah is bidding farewell to the track this season, but he will continue racing on the road in marathons.

Farah’s biggest competition in this race has traditionally come from Kenyans — Olympic silver medalist Paul Tanui and world silver medalist Geoffrey Kamworor could challenge him. U.S. champion Hassan Mead was 11th in the Rio 5000m.
