There are high hopes for the British boxing team in Tokyo and it has been an impressive start for the first fighter in action, women's featherweight Karriss Artingstall.

The 26-year-old, who is a gunner in the Royal Artillery, beat Botswana’s Keamogetse Sadie Kenosi, the world number four, in her opening bout with a unanimous 5-0 win.

Artingstall was dominant throughout as Kenosi struggled with her headguard in all three rounds and she needed to take a time out for it to be adjusted.

She will now face Brazil’s Jucielen Romeu in the round of 16.

Time to take a breath after that road race.

At 10:30 BST, Great Britain's men's hockey team will begin their campaign against South Africa.

An hour later, at 11:30 BST, the GB women's football take on Japan.

Then, at around 12:40 BST, Adam Peaty begins his campaign for gold in the 100m breaststroke.

Here's Richard Carapaz's winning moment.

Of course, the 234km was well worth it for him.

However, if you've ever put yourself through an ordeal and come away with nothing, do let me know. Text and tweet.

One more thought on that road race. Can you imagine slogging your guts for six hours and coming away empty-handed?

Is there a more gruelling event in the Olympics?

It took 63 hours from waters breaking to our first born arriving. That was gruelling. My other half had a rough time too.

Neil: That road race was brutal!

Sarah Wixon: Throughly enjoyed the men's road race at Tokyo 2020. Absolutely in awe of the cyclists and how mentally and physically challenging it is.

GB's Adam Yates, who finished ninth, speaking to BBC Sport: "It was a really tough day but I think we did the best we could. In the end I just didn't have the legs.

"I was cramping everywhere. First race back in a long time and I just did the best I could.

"There was a bit of a head wind on the final straight. I think with the guys there, I was never going to win anyway.

"I tried to go a little bit early on the other side. I'm not sure where I finished in the end but I couldn't have done much more. Good day in the office.

"It was a tough day in general, having two guys down early. Also, I haven't raced in a long time and everyone else is coming from the Tour.

"It wasn't the most ideal prep - but I think we can be happy. We'll come back and try again."

With no medal in that men's road race, Great Britain won't register on the medal table until tomorrow at the earliest. They won't be the only team ending today empty-handed, either...

Men's road race at the Tokyo Olympics?

Completed it.

If you weren't with us earlier, GB's Geraint Thomas retired. He never recovered from a crash that included team-mate Tao Geoghegan Hart.

Phillip Hudson: Six hours of cycling to finish two seconds off of a medal. Pain.

Richard Askam: What an effort from Adam Yates. Nothing left at the end. Such a tough race.

After all that, Adam Yates finished ninth. His brother Simon was 17th.

What a finish. I don't think I've seen people that spent before!

That is some courage we have seen from all the participants.

Everyone was spent in the end.

Carapaz, by the way, has won what is only Ecuador's second ever gold at the summer Olympics.

Wout van Aert of Belgium has been confirmed as the silver medal winner. Tour de France champion Tadej Pogacar from Slovenia has won bronze.

Adam Yates went first, but faded quickly. It was between Tadej Pogacar and Wout van Aert for silver and bronze. Too tight to call.

Go on lad!

Get ready for this battle for silver and bronze.

Adam Yates is in there.

Sprint finish...
