There might not be a bigger favorite in any event in any sport at the Paris Olympics than Katie Ledecky is in the women's 1500m freestyle.

The American distance great owns the 19 fastest times in the event's history and won its Olympic debut in Tokyo by four seconds, which was close by Ledecky's standards.

Roughly 90 minutes after contesting the men's 200m butterfly final, Marchand will be back on the pool deck with a great chance at another gold in the 200m breaststroke.

Though Marchand likely won't be at his freshest for the race, he'll be aided by the fact that China's world-record holder, Qin Haiyang, did not qualify for the final.

Instead, his stiffest competition will likely come in the form of defending gold medalist Zac Stubblety-Cook of Australia. Both men won their respective semifinals Tuesday night.

Tokyo gold medalist Caeleb Dressel missed out on this event at U.S. Trials thanks to breakout swims from Chris Guiliano and Jack Alexy. Both Americans made the Olympic final, but will have to up their pace to reach the podium.
