Targets and Triumphs: Key Highlights from Day Eight of the Paris Olympics

Sha'carri Richardson aims for 100m gold to end the U.S. drought, facing tough rivals from Jamaica. Simone Biles vies for her third gold in the vault final. The day features 31 champions crowned, including highlights from boxing, swimming, fencing, and cycling.

PARIS, Aug 3 (Reuters) - Sha'Carri Richardson will be looking to end the United States' gold medal drought in the women's 100 metres on Saturday but will face fierce competition from Jamaica's jet-heeled sprinters. In all, 31 champions will be crowned on day eight of the Paris Olympics, with U.S. gymnast Simone Biles competing for her third top podium spot of the Games, this time on the vault.

World champion Sha'Carri Richardson's long-awaited Olympic debut got off to a sizzling start on Friday, cruising through her heat with a winning time of 10.94 seconds. Richardson's Olympic dreams came crashing down around her three years ago when she tested positive for cannabis and had to miss the Tokyo Games. The final takes place later on Saturday.

Simone Biles will be chasing her third gold medal of the Paris Games on Saturday as she faces off in the vault final with Brazil's Rebeca Andrade, the only gymnast to ever "stress out" the American superstar. Look out for Andrade's unprecedented triple-twisting Yurchenko vault, which she has yet to debut at the Games. This vault would bring Andrade's scoring potential significantly closer to that of Biles.
