Scotland's Mark Stewart takes the next five points. He's only three points away from a place on the podium.

New Zealand's Keegan Hornblow hurls himself up the standings as he kickstarts a solo attack and laps the field. That takes him up to sixth.

We've got a new leader! The Isle of Man's Matthew Bostock, along with Olivier Bleddyn of Australia, launch a move and they lap the field for a third time.

Bostock leads on 72 points with 54 laps to go.

Twenty points for Wales' William Perrett and he's up to second with 50 points.

Bermuda's Conor White is the only rider who hasn't picked up a point yet.

Ah! Scotland's Logan Maclean was going for the five points there, but he's pipped across the line by Australia's Blake Agnoletto and he has to settle for three.

At least he's on the board now.

Matthew Bostock of the Isle of Man has moved up in the standings.

A 20-pointer for lapping the field helps him storm up to third with 49 points, just two behind New Zealand's George Jackson in the gold-medal position.

There's a long, long... long way to go, though.

This actually is ridiculous, isn't it?

Sixty laps down. Just 100 more to go.

I'm exhausted just watching them out there.

The Welsh riders claim the big points on the latest sprint, with William Perrett getting the five and William Roberts claiming three.

Perrett is sitting in second with 27 points.

A big cheer as Scotland's Elliot Rowe, along with six other riders, lap the rest of the field. George Jackson was in that group and he leads with 30 points.

Rowe is on 20.

That concludes the judo programme.

A relatively disappointing day for the home nations but Emma Reid made sure it wasn't an empty-handed one.

The English judoka held onto her gold from Birmingham in the women's under 75kg category with a cold, classy performance.

Australia's Oliver Bleddyn makes an early move and laps the rest of the field and he gets 20 points for his efforts.

George Jackson of New Zealand gets another five points a few minutes later to take his total to 10.

George Jackson of New Zealand takes the first five-pointer of the points race. England's William Tidball is right behind him to win three points for himself.

There's about six or seven riders out at the front, a quarter of a lap in front of the rest of the field.

A beast of a race.

160 laps. 25 miles.

Strap in, because we're in this for the long haul.

Ask Me Anything

A mass-start race of 40km (160 laps) with points scored in intermediate sprints, which are held every 10 laps.

Five points for the winner followed by three, two and one for the next three over the line.

There are also 20 points on offer for lapping the field.

Tactics vary, with some riders sitting at the back to conserve energy and contest the intermediate sprints, while others try to gain a lap by breaking off the front and rejoining the back of the main bunch.

The winner is the rider with the most points at the end of the race.

We're nearly there, folks. Just one last race in the velodrome and it's going to be a cracker.

Here comes the men's 40km points race...

What a match!

Paula Monta of Tonga thought he'd won it but he only gets to add a yuko to his waza-ari as Canada's John Messe A Bessong got enough of the leg to prevent the ippon.

Monta picked up another yuko but then the Canadian earned a waza-ari of his own to draw the score line closer.

In the dying seconds, Messe A Bessong took Monta to ground but he was only able to collect a yuko to concede a 12-11 loss.

Sixth place finisher in the keirin, Lowri Thomas, has just spoken to us in the mixed zone. She's full of praise for teammate and winner of four golds, Emma Finucane.

"Welsh Cycling and British Cycling do a brilliant job of bringing once in a generation talent through more than once in a generation and Emma is that."
