There's movement at the top end of the leaderboard in the golf as Ireland's Leona Maguire hits back-to-back birdies from the first to move onto six under, seven shots off the lead.

We are still expecting the golf to go to a fourth day but there are contingency plans in place with a tropical storm expected to hit the Kasumigaseki Country Club at the weekend.

It means today's round could be crucial.

If the weather means they cannot play on Saturday, the final round could also be played on Sunday, with the event being declared a 54-hole tournament with the third round leader claiming gold if no play is possible at the weekend.

Round three today and round four on Saturday both start early and begin on split tees, with groups playing from holes one and 10, to avoid the extreme heat and to try finish the event before the expected storm hits.

Dawid Tomala is way ahead of the chasing pack - a gap of almost two minutes with 8km to go.

Looks like gold is going to the Polish athlete unless he somehow fades badly in the closing stages.

David: Looks like they’ve been caught shoplifting and they’re trying to make a quick inconspicuous getaway?

Kelly: Literally looks like me speed walking for the train I’m about to miss

Dan: I've been watching the Olympic Racewalking on mute and playing Bee Gees and disco classics underneath and it works *so well*

Simon Gleave, head of sports analysis, Nielsen Gracenote: "Tokyo 2020 is now Great Britain's fourth best Olympics and second best outside the UK, after Rio 2016. The 51 medals are seven ahead of the number our pre-Olympic forecast had at this stage. Galal Yafai is also guaranteed gold or silver so we have adjusted our projected British medal total upwards to 60, including 18 gold medals as the number of golds is now four ahead of schedule.

"Only London 1908 (146 medals), London 2012 (65) and Rio 2016 (67) have produced more medals for Great Britain than Tokyo 2020.

"Compared to London and Rio at this stage, Tokyo has not produced as many medals with 52 in London and 55 in Rio by this point.

"The 16 golds won so far fall well short of London's 25 and Rio's 22 at this stage."

American Nelly Korda leads the women's golf at the halfway stage after a superb nine-under 62 to go four shots ahead.

The world number one made nine birdies and an eagle but missed the chance of a historic 59 with a double bogey on the 18th hole, to sit at 13 under overall.

Denmark's Nanna Koerstz Madsen and Emily Kristine Pedersen are tied for second with India's Aditi Ashok. Britain's Jodi Ewart Shadoff is level par, while Mel Reid is six over.

Korda doesn't tee off until 09:18 BST with Inbee Park one of the early movers this morning as she moves onto one under through two holes and four under overall.

Whooping at a grapefruit grind and being wowed by reverse triple tail whip, these Olympics have provided many moments where we've cheered on things some of us had probably never heard of a couple of weeks ago.

But like all good things these Games must come to an end. There's just three days of competition remaining, what more magical moments could we witness before the curtain comes down on events in Tokyo?
