What you need to Know about the Olympics on Friday:

SPRINT DOUBLE FOR LYLES

Lyles will take to the track once again to try and complete the prestigious sprint triple by adding the 200m title to his victory in the 100m. The race will take place at 20:30 (18:30 GMT).

PENTATHLON SETBACK

Britain's reigning Modern Pentathlon Champion

Joe Choong

He choked back tears, and said that he felt 'gutted" after finishing 29th in the first fencing ranking round of 36 competitors.

CLIMBING FAST

Veddriq Lenardo of Indonesia won the gold medal for men's speed-climbing, a first Olympic title in history for his nation. American Sam Watson took home a bronze medal despite setting a new world record during his last race.

TABLE TENNIS SUSPENSE

China's men table tennis team defeated France in the semi-finals with a score of 3-0. However, the scoreline did not reflect the close matches that had captivated the French and Chinese crowds.

The Chinese are now aiming to win the gold medals for men's and woman's teams on Friday and on Saturday, in order to sweep the five available at the Games.

FIRST KITEBOARD GOLD

Ellie Aldridge, a British athlete, won the first ever Olympic medal.

Kiteboarding Gold

Lauriane Nolot, of France, won the silver medal and Annelous Lammerts from the Netherlands took the bronze.

KAYAK CHAMPION

Lisa Carrington of New Zealand led her women’s four-person kayak crew to gold, bringing her Olympic total to six golds. She also won one bronze medal with this stunning performance.

In the 500 metre final, the four-man German kayak team beat Australia by just four hundredths of a sec. Spain took the bronze.

STEEPLECHASE FALL

The International Olympic Committee reported that Ethiopian Lamecha Girma has recovered the day following a shocking fall during the final of the men's 3,00 metres steeplechase on Wednesday.

The 23-year old world record holder, who was sprinting full speed at the time, tripped on the third from the last barrier and fell onto the track where he laid motionless for several moments.

Sailing GOLD

Ruggero Tita of Italy and Caterina Banti, the reigning Olympic champions, won gold at the mixed multihull race after a confident final race that confirmed their overall victory.

After battling their way to the front of the fleet, Austrians Lara Vadlau (left) and Lukas Maher (right) won the gold medal in the mixed dinghy.

SPRINT RELAY

The United States made a first step in ending their 4x100m relay drought for men when they won the heats on Thursday. They will have a lot of firepower left to unleash as Jamaica was eliminated after two failed changeovers.

After qualifying the fastest, it looks like the U.S. Women's Team will also be able to take back their title from Jamaica.

MARATHON SWIMMING

Sharon van Rouwendaal, a Dutch iron woman who trained with Moesha Johnston in Australia, won her second Olympic gold medal for 10km marathon swimming.

Chinese Drop Call

China's antidoping agency has urged the International Testing Agency (ITA) to intensify the testing of U.S. track athletes after Erriyon Knighon, an American sprinter, tested positive for trenbolone.

Knighton was found to have a positive test this year, but was not banned from the Paris Games because an arbitrator determined that the likely cause of the result was contaminated meat.

MAKE WEIGHT

Vinesh Phogat announced that she has retired from wrestling after the Indian was disqualified before the Olympic Women's 50kg Freestyle Final on Wednesday.

Phogat, 29, was supposed to compete with American Sarah Hildebrandt to win the gold but she fell 100 grams short. She spent hours in the sauna and starved herself for a whole week to reach her competition weight.
