The U.S. Olympic swim team has started swimming again after an injury-riddled season that saw it finish dead last in the pool at the 2014 London Games.

In an interview with the Associated Press, U.N. Swim director-general Jan-Michael Drysdale said swimming in Rio is a “challenge,” but the Olympics will be the “ultimate test” and the U.R.S.’s best chances of success lie in preparing for it.

The U.K. swimmers, who will face Canada at the opening ceremony on Aug. 6, will be joined in the Olympic pool by the U-23s and the 18-year-old American.

The U-18s are not expected to compete until the summer, Drysda said.

In the past, the U U.Y.s had a very good track record.

The only swimmer in history to finish second at the 1984 Olympic Games in Barcelona was U-19 swimmers Katie Ledecky and Jodie Van den Berg.

The London Games will be their first appearance in the Games since 2012.

Drysdel said he believes the team will have a strong swimming performance and will make a great showing.

But the U.-23s will face some adversity.

U.W. Swimming coach Jim Kratz told the AP the U23s have not been practicing and are having difficulty adapting to the heat and pressure of competition.

The team will also have to cope with the challenges of training in the heat, dealing with the possibility of a virus and dealing with a changing culture.

The swimming team will be supported by a poolside physician, who has been in charge of preparing for the Olympics.

Drysdale praised the swimming team’s dedication to swimming and said he is confident they will be well prepared.

“We’ve seen that when you put in the work and dedication and the hard work and the sweat and the tears and the work that’s required to swim in the water, that you can overcome any adversity that comes your way,” he said.

“I know the U.” team has been very, very dedicated.

We want to give them our all.
