Forgot to mention the women's sprint also gets underway tomorrow, watch out for Victoria Pendleton in that as she looks to defend her title - the final will be on Saturday. Don't forget you will be able to catch all of the action over the next three days here on the BBC Sport website, where Peter Scrivener will be your guide for tomorrow's fun and games. Thanks for joining me tonight, goodbye for now.
Friday starts dramatically for the British team with Sir Chris Hoy and Jason Kenny facing each other in the sprint semi-final. The six-event men's omnium kicks off, with Sam Harrison taking part in place of Ed Clancy, who is ill. Meanwhile, in the non-Olympic events there's a final in the men's points race and in the women's individual pursuit before the night ends in the men's sprint final. Be ready for the fireworks.
So, after two days Britain have four medals, one gold, one silver and two bronze. Plenty more to come over the next three days, here's what tomorrow will bring....
What a night. That was some breathless racing in Apeldoorn with GB adding two more medals to their tally after gold in the team pursuit and silver in the team sprint.
"I'm really happy. I was happy with the time I did in the first round on this, because it's going quite a bit slow. It's great to be in the team with Vicky. I don't really worry about having the Olympic champion in my team, it'd be a lot of pressure if I started to worry about that. It's really important to go under 19 seconds on this track, you never know what you're going to do when you haven't ridden it before. I've got to keep building on that now."
"I want to ride behind the fastest rider and Jess has done a fantastic job. She should be really proud of herself and she's still improving. We've got the right ingredients right here, with a bit more work and focus we'll be smiling I hope. I was pleased to see we really pushed the Australians, Anna Meares has a consistent 18.8-second lap and it's going to take time to get there, but if anyone can do it I'm sure Jess can do it. I feel a lot more confident and tonight has shown I'm going in the right direction. I've got a lot to look forward to.
Time for another medal ceremony, this time it's for the women's team sprint. Jess Varnish and Victoria Pendleton stand to the right of the Australia duo who receive their rainbow jerseys. Thank you's and smiles all round but Advance Australia Fair isn't the anthem Pendleton and Varnish will want to hear in London next summer.
It's not a new world record, but there is a new World Champion in the men's 4km individual pursuit and it's Jack Bobridge who adds another gold to his team pursuit win from Wednesday. Bobridge wins in four minutes 21.141 secs, with Jesse Sergent of New Zealand taking silver and Michael Hepburn of Australia collecting the bronze.
Jack Bobridge leads by two seconds after 2250m and looks fairly comfortable, or has the Australian gone out to early, could Jesse Sergent pull him back? He couldn't, could he?
While GB's focus is very much the 10 Olympic events at the Worlds, a highlight for the purists is undoubtedly the final of the non-Olympic men's 4km individual pursuit, where Australia's Jack Bobridge, who
broke Chris Boardman's 15-year-old world record
in February, is going up against Jesse Sergent of New Zealand. The Apeldoorn track has been slow so far so another record is not expected, but who knows with this talented 21-year-old. They are just about to get underway.
Jason Kenny joins Sir Chris Hoy in the semi-final of the men's sprint after tactically outwitting Shane Perkins and charging to a convincing victory. Kenny will face Hoy in the semi-final on Friday.
In the other semi-final Gregory Bauge will take on fellow Frenchman Mickael Bourgain. Whichever way you look at it, it will be Great Britain v France in the gold medal race.
That's not the end of the racing, by the way. We've still got Jason Kenny racing in his third sprint heat, just about to get going. Kenny looks cool as the race is about to start.
World team pursuit champion Wendy Houvenaghel:
"It's such a relief in some respects but it was a great ride and we worked so well together as a team. I'm so glad we've come away with the gold medal this time. Everyone brings different attributes to this event, it's a team event and a mixture of endurance and sprint really works. I'm so pleased and it's a real privilege to have ridden with these two girls and get that rainbow jersey again.
Finally time to take a breath from what has been a frantic night of racing as the British women's pursuit team head up onto the podium to collect their gold medals and rainbow jerseys... oh and the flowers, don't forget the flowers. Huge smiles all round.
So, Hoy looks in top form in Apeldoorn, but so too does World Champion Gregory Bauge as he cruises past Scott Sunderland and into Friday's sprint semi-final. Fellow Frenchman Mickael Bourgain also qualifies.
It was never going to be that easy, was it? Jason Kenny leads from the front but finds a late burst from Commonwealth champion Shane Perkins too much to handle. That's one heat each. This one will go to a decider.
Sir Chris Hoy eases into tomorrow's sprint semi-final with a comprehensive victory over Robert Fostermann. The arm goes up from Hoy as he crosses the line, much to the delight of the GB fans, his days work is done. Can Jason Kenny follow? He's up next.
A fantastic start from Australia gives the world champions the jump on Jess Varnish and Victoria Pendleton and the British duo are unable to peg back their rivals and take silver in 33.525 seconds. Australia's winning time is 33.237 seconds. That's a third straight world championship title for Anna Meares and Kaarle McCulloch. They will take some beating in the run up to 2012.
AUSTRALIA WIN GOLD IN THE WOMEN'S TEAM SPRINT 1950:
China make the most of an under-performing French duo to take bronze in 33.586 secs in the women's team sprint. Now for GB.
In the other two quarter-finals Gregory Baurge outclasses Scott Sunderland and Mickael Bourgain edges out French compatriot Mickael D'Almeida - only the first of three-heats gone so far, though.
Jason Kenny doesn't like doing things the easy way. The 23-year-old shows an incredible turn of pace to pip Australia's Shane Perkins on the line in his first heat.
Sir Chris Hoy comes from behind to beat German Robert Fostermann in the first heat of his quarter-final. The big Scot has the confidence to hang back and attack late. Very impressive.
BBC cycling commentator Chris Boardman:
"That was really well executed, they made the most of their abilities. It was a punchy ride from Dani King and they can take a lot of confidence from that."
What a dominant ride from the GB pursuit team. Wendy Houvenaghel, Laura Trott and Dani King put in a stunning ride to win the world championship in 3 minutes 23.419 seconds with United States trailing in 3:25.308. Youngsters Trott and King have certainly put their names in the frame for the Olympic team.
GREAT BRITAIN WIN WOMEN'S TEAM PURSUIT GOLD 1925:
New Zealand edge out 2010 world champions Australia in the women's team pursuit third-place race to claim the first medal of the evening. It's a bronze, the same colour medal they won in Copenhagen 12 months ago. GB next up in the final against the United States, Laura Trott to lead GB off.
No go for Matt Crampton in the sprint repechage as he finishes third in his heat. Only the repechage winner will go into the quarter-finals later.
BBC Cycling commentator Chris Boardman:
"I think Jess Varnish may well have booked her place for the Games. It's going to be a fantastic final."
The Australian duo of Anna Meares and Kaarle McCulloch power into first place in 33.342 secs but Lithuania can't bump GB out of the top two. Victoria Pendleton and Jess Varnish will race Australia for gold at 1945 GMT.
Wow, lung-busting 18.9 secs opening lap from Jess Varnish and Victoria Pendleton finishes it off in style to take GB top of the times in 33.356 secs - one heat to go, and it's the Australians against Lithuania.
Here come the top teams. France flying against Germany, although both setting impressive times. France go top on 33.601 secs with Germany second on 33.618 secs
The Ukraine are fastest so far with a time of 34.373 secs, but with the Netherlands out on track the home crowd have found their voice and fancy urging their team into top spot, there's a terrific noise in the Omnisport Velodrome.
Things moving along quickly in the velodrome, the women's team sprint is getting underway. Victoria Pendleton and Jess Varnish will ride in heat seven with the Chinese duo.
It's Australia 2-0 France in the final two heats, Scott Sunderland beating Michael D'Almeida and Shane Perkins edging out the dangerous Kevin Sireau. The three-heat 1/4 finals await the winning riders later tonight.
That's power. World champion Gregory Bauge dominates against Robert Fostermann of Germany and barely breaks a sweat as he cruises to victory.
It's a battle of the Brits. Jason Kenny pips Matt Crampton on the line. Kenny looked confident and well in control there.
Frenchman Mickael Bourgain beats Tsubasa Kitatsuru. Sir Chris Hoy is quickly out on track against Matthew Glaetzer and the Olympic champion puts on a masterclass as he comes from a long way behind to ease past his opponent, nodding to the British contingent in the stands as he crosses the line.
Right then, almost ready to get underway at the velodrome. Refresh this page to get the video coverage up top. Sir Chris Hoy will get GB's evening going in heat two of the men's sprint.
You might be thinking there are a couple of names you don't recognise in the British squad at the Worlds, worry not. Sam Harrison, 18,
Laura Trott, 18, and Danielle King, 20,
are making their senior world championship debuts at this event, but you wouldn't think so from the way they are performing. GB cycling head coach Shane Sutton says they have all been picked on form and there's a strong chance they could feature in London. Exciting times.
_SamHarrison_ on Twitter:
Sam Harrison was scheduled to take part in the individual pursuit today but having taken Ed Clancy's place in the omnium, GB pulled him out, meaning he will have to wait until Friday for his track return. Judging by his tweet (below), it seems he's not a man who enjoys time off.
"Never thought I'd be someone to struggle to do nothing all day, but today really has pushed me to my limits!"
Quick amendment to 1800. The live video coverage will actually start at 1830 GMT. Apologies if you have been watching a blank screen patiently, expecting to see some of the finest track riders in the world, it's coming... soon.
By the way, our man on the ground in Apeldoorn is prolific tweeter
who has produced this
beauty of a guide
to what is going on at the five-day event, and why it matters.
All set then? Good. But don't forget you need to get involved too. How? Easy. Send me a tweet using the hashtag
or text me using 81111 (UK)
Of course you don't have to rely solely on me to bring you the best from the track tonight, oh no, you can watch live coverage on the BBC Sport website (but in the UK only I'm afraid)
and on the red button
from 1800 to 2100 GMT
, and listen to live commentary on BBC 5 live Sports Extra
from 1905 GMT
Quick formality for you, here's the important figures from this morning's action: WOMEN'S TEAM PURSUIT
1. Great Britain 3 min 23.642 sec
2. United States 3 min 23.965 sec
3. New Zealand 3 min 24.701 sec
4. Australia 3 min 25.253 sec
Despite the lack of gold medals on day one, it wasn't all doom and gloom in the Netherlands. British cycling legend Chris Boardman picked out the
emergence of 18-year-old Sam Harrison
, who came into the team pursuit for the ill Ed Clancy, as his highlight and Sir Chris Hoy felt the sprint team were
"heading in the right direction"
ahead of London 2012.
The pursuit trio of Wendy Houvenaghel, Danielle King and Laura Trott will go for gold at 1915 GMT
, but there's plenty to focus on before then. After coming through two qualifying rounds this morning, Sir Chris Hoy, Jason Kenny and Matt Crampton are involved in the sprint 1/8 knock-out round at 1830 GMT
and that's followed by qualifying for the women's team sprint final at 1850 GMT
, where Victoria Pendleton and Jessica Varnish will attempt to put themselves into contention for the rainbow jersey.
Evening, all. So, the British men had to settle for
bronze medals in the team pursuit and team sprint
on the opening day of the 2011 Track World Championships on Wednesday. But tonight GB's women take centre stage at the Omnisport Velodrome in Apeldoorn and after a blistering performance in qualifying this afternoon we could see a first British gold medal when the pursuit team take on the United States in the final.
