A dramatic photo finish in rowing, a runner who finished her heat with one shoe and the world fastest woman is crowned at the Rio Olympics.
Here are some noteworthy numbers from Day 8 of the Summer Games:
1,001: The U.S. took home its 1,000th and 1,001st gold medals of the Olympic Summer Games Saturday when the women's and men's swimming teams won each of their 4x100-meter medley relays. The women were led by Simone Manuel, the men by Michael Phelps.
28: How many gold, silver and bronze medals Michael Phelps has won in the most decorated Olympic career ever. His last medal at Rio was gold (No. 23), won in the 4x100-meter medley relay, and Phelps says he won't be back at the Olympics to collect more — he's retiring from Olympic competition.
10.71: How many seconds it took Elaine Thompson, of Jamaica, to become the fastest woman in the world. She finished the 100-meter dash with daylight between her and double defending Olympic champion Shelly-Ann Fraser-Pryce, who took bronze.
34: The world ranking of tennis player Monica Puig, who won Puerto Rico's first gold medal by defeating No. 2-ranked Angelique Kerber, of Germany, Saturday. Puig is also the first Puerto Rican woman to win any medal.
30: The number of people who were detained Saturday while protesting against the Olympics following clashes with police. Rio state security officials said in a statement that the protesters were wielding long planks of wood and throwing rocks at police as they tried to march toward the Olympic stadium, where track and field events are being held. Left-wing critics of government corruption and hefty spending on the Olympics at a time of deep recession have held several small protests in the week since South America's first games have begun. They say money is badly needed to fund schools and hospitals.
22: The number of gold medals to be won in 13 different sports on Saturday. Competitions wrap up in swimming and rowing — but they are just heating up in track and field, which will award five golds: for the women's 100 meter sprint and the heptathlon, and the men's 10,000 meters, discus and long jump. There are four medals up for grabs in swimming.
10.07: The number of seconds it took Usain Bolt to run his 100-meter heat, his first race at the Rio Games. His time trailed that of his longtime rival Justin Gatlin by .06 seconds, but Bolt was running into a headwind while the American had the wind on his side. The 60,000-capacity stadium was filled with noisy fans, a stark contrast with the opening day. The crowd had been difficult to calm and silence ahead of the start of races, but when Bolt put his fingers to his lips for silence, all went quiet.
Nearly 1 million: Gallons of of clear water being transferred from a practice pool to the Olympic diving pool, which was drained of green water Saturday, according to The Associated Press.
9:34.70: The time it took Ethiopia’s Etenesh Diro to finish women's 3,000-meter steeplechase after having run the last half mile of the semifinal with only one shoe. Diro was leading her heat when her right shoe became loose. She finally yanked it off, caught up to some of the runners and ended up finishing seventh. She was originally knocked out of the competition, but advanced to the final on appeal following protests from the Ethiopian team.
6:41.34: The number of minutes it took for a dramatic photo finish in the men's single sculls. Olympic champion Mahe Drysdale of New Zealand and Croatia's Martin Damir both clocked the same time but officials called the race for Drysdale after studying a photo of the finish.
3: The number of consecutive Olympic gold medals the U.S. rowing team has won in the women's eight. The U.S. beat Britain and Romania on the final day of the Rio regatta to win the third gold. The U.S. has dominated the event since 2006 and now has 11 straight world and Olympic titles, an outstanding dynasty in team sports.
1: The number of Russian track and field athletes allowed to compete at the Rio Games. But long jumper Darya Klishina was booted before the competition begins on Tuesday. She's appealing the ban. IAAF spokesman Yannis Nikolaou told the AP Saturday that the governing body revoked Klishina's eligibility based on new information it received last week. It's not clear what the new information is. The Russian team was banned over allegations of a widespread, state-sponsored doping program but Klishina was originally allowed to compete in Rio because she is based in the U.S.
