For the first time since 1904, golfers will tee off at an Olympic Games, while swimming legends Michael Phelps and Ryan Lochte renew acquaintances in the pool on another jam-packed day at Rio 2016.
Sensational American gymnast Simone Biles goes for the second gold of a possible five in the women's artistic gymnastics individual all-around final, while the first rowing and track cycling medals will be awarded.
Below we take a look at the events to watch on day six in Rio.
GOLF ENDS 112-YEAR ABSENCE
Golf's return to the Olympics has already been marred by controversy, with worries over the Zika virus and scheduling concerns prompting a spate of withdrawals. None of the world's top four - Jason Day, Dustin Johnson, Jordan Spieth and Rory McIlroy - are competing in Rio.
But home hope Adilson da Silva teed off at 07.30am local time, putting the focus purely back on the action on the course.
Open champion Henrik Stenson is the top-ranked player competing for the men's individual title, but is sure to face stiff competition from Masters green jacket winners Bubba Watson and Danny Willett as well as the likes of Rickie Fowler, Justin Rose and Sergio Garcia.
PHELPS LOCKS HORNS WITH LOCHTE IN MEDLEY
It has already been an extremely successful Games for Michael Phelps, who has silenced any doubters he may have had with three gold medals - taking his career tally to 21.
Phelps now has 25 medals overall following his wins in the 200 metre butterfly, and 4x100 and 4x200m freestyle relays, and the most decorated Olympian of all time can add to his mightily impressive resume in the 200m individual medley.
Standing in his way is American compatriot and world record holder Lochte, who claimed silver behind Phelps in London four year ago and was beaten by him in the semi-final on Wednesday.
Japan's Kosuke Hagino could provide a threat and Thiago Pereira will be looking to win Brazil's first swimming medal of the Games, but it is tough to look beyond an outcome other than another moment of glory for Phelps.
BRILLIANT BILES SEEKS ALL-AROUND GLORY
Simone Biles predictably stole the show in the women's team final by guiding United States to the gold in majestic fashion.
The 19-year-old, a 10-time world champion, dominated on all four apparatus, scoring a 15.933 on the vault and a 15.800 on the floor, living up to her reputation as the world's greatest gymnast as the USA won by over eight points.
Biles is predictably the hot favourite to take the all-around title and few would bet against her producing another dominant performance in the next leg of her quest to become the first gymnast to win five golds at a single Games.
ROWERS PLAY CATCH-UP
After losing a second day of competition because of high winds on Wednesday, organisers will hope that the conditions for Thursday's rowing action at Lagoa remain clear.
The backlog caused by Wednesday's postponement means six golds will be up for grabs, with finals taking place in the men's and women's quadruple sculls, men's pair, men's four and men's and women's double sculls.
Meanwhile, British duo Helen Glover and Heather Stanning - unbeaten since 2011 - will seek to reach the final of the women's coxless pair.
CYCLISTS TAKE TO THE TRACK
After the chaos of the road races and time trials, the cycling action moves to the confines of the velodrome.
Qualifying for the men's and women's team pursuit will take place, but the first track cycling gold to be awarded is in the men's team sprint.
Great Britain are the defending champions, with Callum Skinner joining Philip Hindes and Jason Kenny - who won with Chris Hoy in London - while the French team of Gregory Bauge, Michael D'Almeida and Francois Pervis will be out to go one better than their silver four years ago and deliver an eighth gold in this event for France.
