All you need to know about Day 4 of the Tokyo Olympics.
Russia's gymnasts took gold in Tokyo on Tuesday in one of the biggest upsets of the Olympics so far.
Barred at the Olympics from using its name, flag, or anthem over a systemic doping scandal, the team hung their medals around each other's necks to the music of Russian composer Tchaikovsky.
Although the Russian team's triumph was attributed to the departure of U.S. gymnastics superstar Simone Biles - who withdrew from the tournament, citing a 'medical issue' - they won by 3.5 points, a large margin.
Here are today's results:
The first gold medal of the day went to Flora Duffy of Bermuda who won the women's triathlon.
It's the first-ever Olympic gold medal for the small island of about 64,000 inhabitants and the first medal of any kind since 1976.
The 33-year-old Duffy had never finished higher than eighth in her previous three Olympic triathlons.
Great Britain’s Georgia Taylor-Brown won the silver medal and American Katie Zaferes won bronze.
