The first Olympic skateboarding champion will be crowned on day two of the Tokyo Games.

Ariake Urban Sports Park will be the venue for the first skateboarding action in Olympic history on Sunday.

Elsewhere, it will be the turn of the women to contest the cycling road race after Richard Carapaz produced a brilliant ride to take gold for Ecuador on Saturday.

Stats Perform picks out of some of the standout action to look out for at the end of the opening weekend of competition.

HUSTON FAVOURITE TO MAKE SKATEBOARDING HISTORY

The men's street will be the first skateboarding event, with four heats followed by a final at 12:25 local time.

Nyjah Huston of the United States is the favourite to top the podium, with 16 street skateboarding medals to his name in the X Games.

Tokyo-born Yuto Origome won gold at the World Street Championships in Rome this year and it would be a great story if he can follow that up with an Olympic triumph on home soil.

Skateboarding great Tony Hawk said on Saturday of the sport's introduction: "I'm surprised it took this long for them to figure it out.

"I believe they needed a youthful energy to the summer Games and it's overdue."

DUTCH DUO UNPRECEDENTED DOUBLE

Anna van der Breggen and Marianne Vos have already won Olympic gold medals and they will go in search of a second in the women's road race.

No female cyclist has won the event twice, but the 2012 champion Vos and defending champion Van der Breggen will start the course at Musashinonomori Park looking to achieve that feat.

EYES ON THE POOL – AND ON THE BEACH

The first swimming medals of the Games will be handed out on Sunday following Saturday's heats.

There is an open field in the men's 400 metre medley final – the first event of the day – after home favourite Daiya Seto failed to qualify.

The women's event does feature Hungary's Katinka Hosszu, though, as she aims to protect her 2016 gold, won with a world-record time that stands to this day.

Meanwhile, Australia will take to the pool confident of another gold in the 4 x 100m freestyle relay final, boasting the title, the world record and by far the best qualifying time.

A new water sport should garner some attention, though, as surfing makes its Olympics bow.

Tsurigasaki Surfing Beach – preferred to a wave pool – plays host for the first and second rounds on Sunday.

Reigning world champions Italo Ferreira and Carissa Moore will hope it is a debut to remember.

USA TO GET ON THE BOARD?

While China are sitting pretty already with four medals, the United States will hope not to have to wait too much longer for their first.

Not since Munich 1972 had they ended the first day of the Games without a medal as was the case on Saturday.

The basketball medals are a long way off being handed out, but plenty of American focus will be on Team USA's opener against France.

Preparations for Kevin Durant and Co have not been ideal and Les Bleus beat USA at the 2019 FIBA Basketball World Cup.
