It was heartbreak for GB's Kimberley Woods in the women's canoe slalom final, who was unable to recover after an early penalty.

The final group matches of the women's football tournament have just started.

World champions the United States are up against Australia - led by Chelsea striker Sam Kerr.

New Zealand v Sweden are also in action and it's a battle for the top spot in the group.

Team GB face Canada in their final group match at 12:00 BST.

Can she roar back into contention?

Great Britain's Zoe Smith made her first Clean and Jerk attempt at 113kg look simple.

She will be adding on another 2kg when she addresses the bar for a second time.

Now then.

Liam Broady - who was the last man into the singles draw in Tokyo - has just closed out a very tight opening set over Polish seventh seed Hubert Hurkacz.

Another one and he's into the third round...

And here is what is yet to come:

• Equestrian: British rider Charlotte Dujardin will be looking to add to her three Olympic titles as she joins veteran Carl Hester and debutant Charlotte Fry in the team dressage, which is just getting started.
• Gymnastics: One of the Olympics' biggest TV audiences will be expected for the women's team final (11:45-14:10 BST). The United States, led by Simone Biles, are the favourites but can Britain get in the mix for a medal?
• Rugby Sevens: Great Britain face the USA in the men's sevens quarter-finals (10:00 BST).
• Football: Team GB's final women's group game against Canada (12:00 BST)
• Weightlifting: Sarah Davies is in action in the 64kg class from (11:50 BST).
• Taekwondo: GB's Bianca Walkden competes for a bronze medal in the +67kg class (13:00 BST).

Here is your 09:00 look at what's happened so far on day four:

• Swimming: Britain's Tom Dean claimed a stunning gold ahead of team-mate Duncan Scott in a thrilling 200m freestyle.
• Triathlon: Britain's Georgia Taylor-Brown produced a superb run toearn a silver medal in the women's triathlon,fighting back from a bike puncture which left her well adrift of the leaders. Bermuda's Flora Duffy claimed a historic first gold medal for her nation.
• Taekwondo: GB's Bianca Walkden suffered a last-gasp defeat to South Korea's Lee Da-bin in the +67kg semi-final, while compatriot Mahama Cho lost to China's Sun Hongyi in the last 16 of the men’s +80kg.

This is my first outdoor venue and what a venue it is!

The GB team here were comfortable qualifiers.

They're absolutely up with a chance of a gold medal.

Right then, how are we all doing?

A bit bleary-eyed after another late night and/or early morning to keep up with all the action?

Do keep sending in your thoughts to #bbcolympics.

The team dressage gets under way shortly, where Charlotte Dujardin is aiming for a fourth Olympic gold medal...

Great Britain's Zoe Smith fails with her third and final snatch attempt at 91kg.

Her successful lift of 87kg is the lowest so far in the competition.

Onto the Clean and Jerk.

With 10 medals in total so far on day four, this is the best start for a British team in Games history - and the highest number of gold medals for Britain at this point.

Simon Gleave, head of sports analysis at Nielsen Gracenote, said: "Great Britain has made its best start to an Olympic Games with at least 10 medals after four days of competition.

"This smashes the record for most British medals in the first four days which was six in 2000, 2008 and 2016. Great Britain's recent successes at London and Rio began with four and six medals respectively in the opening four days."

Gracenote's virtual medal table projects a total of 52 medals by the end of the Games. UK Sport set a medal target of between 45 and 70.

Taekwondo has ended in disappointment for Bianca Walkden and we are all feeling it...

Kelechi Ehenulo: Taekwondo is a cruel sport.

Simon Wells: Lutalo speaks for a National! Gutted!

Matt Reynolds: Taekwondo has to be one of cruelest sports I've ever watched.

It's a good start for GB sailers Saskia Tidey and Charlotte Dobson. The pair are leading the way after the first three women's skiff 49er with two race wins and a sixth-place finish.

Teams accrue points after each of the 12 races equivalent to where they finish (eg. one point for coming first, two for coming second and so on). Crews then discard their worst race score, and the 10 boats with the lowest totals will progress to Monday's medal race.

Kimberley Woods will be absolutely gutted.

She's a superb paddler and she has plenty of time ahead of her but that first penalty really put her off. After that she just struggled to get the composure.

Kimberley Woods has stopped and her shoulders have dropped.

She's close to tears, she's utterly devastated with that.

It didn't start well but she was absolutely here to win a medal.

Your heart goes out to her. You just want to give her a hug.

It's not to be for GB's Kimberley Woods in the women's canoe final.

A penalty throws her off and a final time of 121 seconds leaves her out of medal contention. The 25-year-old looks devastated.

Great Britain's Bryony Pitman is flying through to the quarter-finals after winning her last-16 tie with Mexico's Aida Roman.

Pitman won 6-2 and had a huge smile on her face as she walked off.

There is to be no medal for Great Britain's Evie Richards in the women's mountain bike cross-country - though she crosses the line in a very creditable seventh place.

It is all about Switzerland though as they complete a magnificent 1-2-3.

Jolanda Neff dominated from start to finish to take gold more than a minute clear of compatriots Sina Frei and Linda Indergand.

Simon Gleave, head of sports analysis at Nielsen Gracenote, said: "The Swiss have not filled all the podium places in a Summer Games event for 85 years, since finishing 1-2-3 in the floor exercise of men's gymnastics at Berlin 1936."

Just heartbreaking for Bianca. She's put everything into this. She's won everything there is to win in the sport - except the Olympic Gold.

She has to treat the Bronze medal match now as the gold medal match.

Chris King: Absolutely heartbreaking! What an incredible match, literally down to the last second

Make sure you tune in for Bianca Walkden's bronze medal match, which will take place at 13:00 BST.
