What to watch for as track and field continues.

TOKYO — Athletes in track and field spent the first half of the year taking aim at — and shattering — a smorgasbord of world records. No one would be surprised to see more of them fall in the coming days, when runners and jumpers take center stage at the Games. Despite the absence of fans, Olympic Stadium will be full of drama.

There are 10 consecutive days of competition, running from July 30 through Aug. 8, when the men’s marathon will punctuate the festivities in Sapporo, about 500 miles north of Tokyo, where organizers expect cooler weather.

The finals are typically at night, though a few are set for midday so they can be broadcast to a prime-time audience in the United States. The final two nighttime sessions, on Aug. 6 and 7, will be packed with finals, including the men’s and women’s 1,500 meters, the women’s 10,000 meters and several relays. The relays are often exciting, and the Americans have been pretty good at them — whenever they manage to hold onto the baton.

Who to watch

• On the women’s side in the 400-meter hurdles, two Americans, Dalilah Muhammad and Sydney McLaughlin, are likely to renew their rivalry with an Olympic gold at stake. At the U.S. trials last month, McLaughlin broke Muhammad’s world record to finish first. But Muhammad is still the defending Olympic and world champion, and her mechanics are pure artistry.

• The men’s 400-meter hurdles final tonight pits Karsten Warholm of Norway, fresh off his own world-record performance, against Rai Benjamin of the United States, who owns the third-fastest time in history.

• Any list like this needs to include Allyson Felix, 35, the grande dame of U.S. track and field. Felix, a six-time gold medalist, is set to compete in the 400 meters in her fifth and final Olympics.

• Shelly-Ann Fraser-Pryce of Jamaica, 34, is already a two-time Olympic champion in the women’s 100 meters. She hopes to win yet another gold, this time in the 200 meters. She won the silver in 2012.

• Sifan Hassan of the Netherlands is planning something truly audacious: She is entered in the 1,500 meters, the 5,000 meters and the 10,000 meters. And after winning the 5,000, she might just be the favorite in the next races, if she can survive multiple rounds.

• At 21, Mondo Duplantis holds the pole-vaulting world record. He grew up in Louisiana but competes for Sweden, his mother’s home country.
