Step one and we're on our way.

Shaken off a bit of rust and got rid of any nerves and here you are cursing through to the next stage to take on the world number 2.

As Olympic debuts go, that's not bad from Charley Davison.

Watch key moments from the early events of day two at the Tokyo Olympics including a swimming shock, new sports taking centre stage and heartbreak for Jade Jones.

Cheddar came out very strong in the opening round but Davison matched her for workr ate and it was the accuracy and punch selection that was the difference.

She will be really pleased, a real confidence boost for the GB camp. It was an excellent display. It couldn’t have gone any better.

A very impressive performance from Great Britain's Charley Davison. She is through to the last 16 of the women's fly 48-51kg with a unanimous points victory over Rabab Cheddar of Morocco.

She will face the tournament number two seed Yuan Chang of China next.

James Williams: Bradly Sindon take a bow, wonderful comeback, go for gold.

Adam Bond: What a performance from Bradly Sindon! Loved watching that.

Richard: Bradly's kicks are Sinden him to the final!

Like what you did there Richard.

Fantastic start by Great Britain's Charley Davison, she has taken the opening round 10-8 against Rabab Cheddar of Morocco in the women's fly 48-51kg.

Davison, who is making her Olympic debut, returned to boxing in 2019 after seven years out, during which time she had three children.

Simone Biles was in qualifying action a little earlier, and here's how the American performed with her beam routine...

Once again Bradly showed the resilience, the mental fortitude that no matter what the situation is he can always come back from behind. He was seven points down at one point and he pulled it back and now Bradly Sinden is Team GB's first medallist of this Olympics.

I wonder what's going through Bradly Sinden's head right now? He has a little bit of time to recover from that semi-final victory before going for gold against Uzbekistan's Ulugbek Rashitov at 13:45 BST. Make sure you tune in...

Bradly's key to victory is really that close range, he got close to his opponent, and he is really good at mixing in those headshots. He is very good at getting his leg around from those awkward angles.

If you're just catching up with what happened so far this morning, here's a quick look...

• Great Britain's first Tokyo 2020 medal is guaranteed as Bradly Sinden reaches the men's taekwondo final (about 13:45 BST)
• But two-time Olympic taekwondo champion Jade Jones lost her first round match with Kimia Alizadeh, ending her hopes of winning a third gold in Tokyo
• Two-time defending champion Andy Murray has withdrawn from the men's singles with a minor thigh strain.
• Australia's world number one and recent Wimbledon champion Ashleigh Barty is out in the first round of the women's singles.
• World record holder and Olympic champion Adam Peaty breezed into the 100m breaststroke final in a time of 57.63.
• US golfer Bryson DeChambeau and Spain's Jon Rahm are out of the Olympics after testing positive for Covid-19.
• And 18-year-old Tunisian Ahmed Hafnaoui won a superb gold in the men’s 400m freestyle.

Great Britain's Lizzie Deignan, who finished 11th, on BBC TV: "It was a weird old day, I was between a rock and hard place really. From midway through I was on my own but unfortunately on my own but also marked so I didn't have the freedom to ride as a solo rider. Tactically I think I did the right thing it just didn't go my way.

"It was a weird race, although there are small teams there are agendas within team. Because the race is so hot and so humid all of the moves were a bit blunted, there wasn't that kind of spark. It was a defensive race but still really hard.

"I'm obviously really disappointed but I have the perspective that I put myself in the position to be here, I have had a great team behind me. We have had a pandemic and we have still had an Olympics and there is so much to be thankful for. "
