Emily, Laura Trott is my hero too.

Here comes sprint number eight and it's not one that will worry Trott.

David Puckridge: @LauraTrott31 is just amazing. A marvel. Remarkable. All the superlatives!

Andy Battle: @LauraTrott31 is simply outrageous. The best track cyclist ever?

Emily Sutton: Laura Trott is my hero - I've never been so amazed or impressed by anything as I am by her cycling and power.

Seconds after Canada should have scored the equaliser, Sara Däbritz  makes it 2-0 with a low, long-distance shot to put Germany within touching distance of the final.

Laura Trott has a 29-point advantage and the three at the front for this sprint are not in the gold medal hunt.

Twenty-nine laps until Trott makes history.

Germany's Stephan Feck, receives a penalty after a restart dive. 

...You may remember Feck from London 2012 where he drew attention, after a flop dive. 

Niiice. The top three go head-to-head-to-head on sprint six.

Guess who won?

Laura Trott.

Jolien D'Hoore and Sarah Hammer are only focusing on each other - they are deadlocked on 200pts in silver position.

Croatia's Sandra Perkovic takes the gold in the women's discus final, throwing a distance of 69.21m.

Over half of this race gone and Laura Trott is in a stronger position now than when she went into this final event.

It's starting to get confusing now.

Laura Trott and Amelie Dideriksen go for sprint points and have to weave through the back markers as they charge over the line.

Trott is 28 points clear. She can smell the gold... if gold smelt of anything.

As it stands:

Trott - 201

Hammer - 177

D'Hoore - 176

Look at that battle for silver.

Great Britain's Hannah Mills and Saskia Clark will win gold in the women's 470 in Rio - just so long as they finish Wednesday's medal race.

Mills, 28, and Clark, 36, hold a 20-point lead going into the finale, after finishing second and third in Tuesday's races.

"The Brits just have to successfully complete the double points Medal Race without disqualification," says British Sailing. , external

“Lost for words – I can’t believe it!” Mills told BBC Sport's Shirley Robertson.

Clark added: “For the last three years it’s been a bit of a joke saying we want to be 20 points clear going into the medal race, because it’s so hard, and we are! I can’t believe it.”

Laura is an incredibly tenacious and gutsy rider. She is very strong willed and a real fighter.

Five riders lap the main field and that will give them all 20 points. It doesn't affect the top three of Trott, Hammer and D'Hoore though.

And Trott snaffles a cheeky point on the sprint.

Ah, the fabled fast food restaurant in the athletes' village.

Apparently the food is free - and it's now become a tradition to gorge yourself after your competing is done.

Hindes will be a mess after this lot...

This is the worst case scenario for the podium placed riders behind Trott.

Sprint number three... there's five riders at the front and none of them are a threat to Laura Trott. They cross the line and this is perfect for Trott, let riders who are out of the picture hoover up all the points her rivals could have claimed.

Belgium's Jolien D'Hoore, one of Laura Trott's closest rivals, makes a move ahead of the second sprint and Laura Trott marks her.

D'Hoore takes second and 3pts, Trott takes third and 2pts. Sarah Hammer has taken five points so far and is second, 22 points behind Trott.
