The men's Olympic golf event starts in Tokyo on Thursday and Caeleb Dressel goes for more glory in the pool.
A new golf champion will be crowned this weekend at the Kasumigaseki Country Club with Justin Rose, who won in Rio when the sport returned to the schedule for the first time since 1904, not selected for Team GB.
Dressel has already won a relay gold in these Games and the American could be back on the top step of the podium again after the 100 metre freestyle final, while there will be no Simone Biles in the women's individual all-around competition.
Stats Perform picks out some of the events to look out for, including the start of the women's rugby sevens competition.
MORIKAWA FAVOURITE FOR GOLF TITLE
Collin Morikawa won The Open at Royal St. George's in Sandwich this month and is favourite to add a gold medal to go with his claret jug.
Morikawa's fellow American Justin Thomas is also in with a great chance of taking the title, while Rory McIlroy is in the medal hunt and Hideki Matsuyama goes for gold on home soil.
Asked what it would mean to him to win a medal, McIlroy said: "I don't know what it would mean. I never dreamed of that.
"I dreamed of claret jugs and green jackets. I never dreamed of winning the Olympics, so I don't know what it would mean until you actually got one.
"It's a hard one to put into words. If it wasn't an option for you growing up and dreaming about it ... maybe I could articulate it a little better if I was in possession of one."

DRESSEL POISED FOR ANOTHER GOLD
Dressel threw his gold medal to team-mate Brooks Curry in the crowd after winning the 4x100m freestyle title this week.
Curry had taken Dressel's place in the team for the qualifying heats before sitting out the final and was rewarded for the part he played by a team-mate who won three golds in Rio five years ago.
Dressel will be keeping his medal around his neck if he retains the 100m title he claimed in Brazil.
The men's 800m freestyle, women's 200m butterfly, men's 200m breaststroke and women's 4x200m freestyle relay finals will also be staged on Thursday.
LEE AND ANDRADE EYE INDIVIDUAL GLORY
There will be a new individual all-around gymnastics champion after defending champion Biles withdrew.
American icon Biles opted out of the event to focus on her mental health after completing only one apparatus in the team competition at the Ariake Gymnastics Centre, having registered the lowest score of the first rotation.
Biles opened up on her struggles after Team USA took silver and it was no surprise when she decided not to go for individual gold again.
Sunisa Lee, Biles' team-mate, and Rebeca Andrade of Brazil are among the standout contenders to win gold in the absence of the 24-year-old star.
AUSTRALIA START SEVENS DEFENCE AGAINST HOSTS
It is the turn of the women to serve up rugby sevens entertainment after Fiji retained their men's title on Wednesday.
Defending champions Australia take on hosts Japan in their first Pool C match at Tokyo Stadium.
New Zealand, silver medallists in Rio, get under way against Kenya in Pool A on the first of three days of competition.
