Cycling time trials are among the highlights on what promises to be a captivating day five at the Olympic Games on Wednesday.
Japanese gymnast Kohei Uchimura will attempt to defend his individual all-round title on Wednesday, while the women's table tennis final will be contested and another four swimming gold medals will be won.
UCHIMURA TO CONTINUE ALL-ROUND DOMINANCE?
The magnificent Uchimura won gold in the men's team final at Rio Olympic Arena on Monday and it would be a turn up for the books if he fails to take the individual all-around title two days later.
Ten-time world champion Uchimura has won every individual all-around gold medal since 2009 and will be expected to top the podium once again in Brazil.
Uchimura racked up a massive bill for playing Pokemon Go in the Olympic village and fell from the high bar in preliminary qualifying on Saturday on what has so far been an eventful Games for the 27-year-old.
FROOME EYEING TIME TRIAL GOLD
Chris Froome missed out on a medal in a dramatic men's road race on Saturday, but the three-time Tour de France winner will be expected to mount a stronger challenge in the time trial.
The Brit won bronze at his home Games in London and showed his time-trial prowess by winning stage 18 of the Tour last month, but faces strong competition over the 54.6 kilometre course.
Tom Dumoulin of the Netherlands is well fancied to be in the medals, while Germany's Tony Martin should also be in the mix in an event which starts at 10am local time.
The women's time trial gets going at 8.30am local time, with Dutch rider Ellen van Dijk and New Zealand's world champion Linda Villumsen ones to watch.
ROWING FALLS VICTIM TO WEATHER AGAIN
The men and women's quadruple sculls finals were due take place at the spectacular Lagoa venue, but Wednesday's rowing schedule was wiped out by the weather.
High winds forced organisers to cancel the day's proceedings, marking the second time during the Olympic regatta that rowing has been cancelled because of weather, with last Sunday's action also having been postponed due to the conditions.
Places in the final had been set to be decided in the women's pairs, lightweight men's and women's double sculls, men's fours, as well as the men's and women's eights - with the postponement putting further strain on the schedule-makers.
MCEVOY AND HOSHI AIMING TO TAKE CENTRE STAGE
After yet more heroics from Michael Phelps in the pool on Tuesday, Natsumi Hoshi and Cameron McEvoy are among the swimmers eyeing gold at the Olympic Aquatic Stadium on the fifth day of competition.
Hoshi claimed bronze in the women's 200 metre butterfly in London four years ago, but is looking to add an Olympic title after being crowned world champion last year.
Australia's McEvoy is favourite to win the men's 100m freestyle final, while the men's 200m breaststroke and women's 4x200 freestyle finals are also on the schedule.
