Your last chance to watch Usain Bolt race is very likely Saturday.
Bolt, one week after being upset in the world championships 100m final, is expected to anchor the Jamaican 4x100m relay team during NBC’s live coverage from London from 3-5 p.m. ET.
Bolt and the Jamaicans crossed the finish line first in all seven Olympic and world championships relays dating to the 2008 Beijing Games.
However, the island nation is losing its sprint dominance. Not only was Bolt relegated to 100m bronze by Americans Justin Gatlin and Christian Coleman, but Jamaica also lacks depth.
