The United States led the way with 30 total medals at the 2017 World Championships, which more than doubled the tally of the second-best nation, Kenya (11).

The team is once again stacked with top contenders, including Coleman, who won two silver medals in London. He finished ahead of Usain Bolt in the 100-metre final but lost out to Justin Gatlin, and ran the anchor leg in the 4x100-metre final, finishing behind Great Britain.

Coleman isn't without controversy. Per CNN's Ben Morse, he escaped a one-year ban for violating anti-doping rules thanks to a loophole in the regulations, allowing him to compete in Doha.

He seemingly made a mistake in the "whereabouts" system on three occasions in one year, but Coleman argued that "filing failures relate back to the first day of the quarter," and as such, the three missed tests spanned more than a year.

He criticised USADA for how it handled the matter:

Now eligible to compete, he won't face Noah Lyles, one of the other top contenders for the gold in the 100 metres. Lyles has decided to focus on the 200-metre sprint. Reigning champion Gatlin remains a threat, and NCAA champion Divine Oduduru has shown tremendous speed this season but could be fatigued after the long collegiate season.

The 33-year-old Allyson Felix, winner of 11 World Championships gold medals and six Olympic gold medals, will be competing at the event for the ninth time, and the first time since giving birth to a daughter in 2018.

She has been building up her form well, showing excellent pace earlier this month:

Felix is expected to be a part of the 4x400-metre relay team. She finished sixth in the individual event at the U.S. Championships this summer.
