|World Para-athletics Championships|
|Location: London Stadium, London Dates: Friday 14 July – Sunday 23 July|
|Coverage: Commentary on BBC Radio 5 live, BBC World Service and live updates on the BBC Sport website and app|
The London Stadium will come alive on Friday for 10 days as the World Para-athletics Championships head to the home of the 2012 Paralympic Games.
It is being billed as the biggest edition of the event ever, with more tickets sold than in all of the eight previous championships combined.
But who are the big names, when are the big races and how can you keep across the action? Here is everything you need to know.
When is it on?
The championships open on Friday evening and run until Sunday, 23 July. There are evening sessions every day, as well as morning sessions from Saturday 15 to Tuesday 18 July and on the final Saturday and Sunday.
Don't West Ham play at the London Stadium now?
They do, but they have to share. Last weekend's Anniversary Games, the World Para-athletics Championships and the World Athletics Championships, which run from 4 to 13 August, are all being held at the venue this summer.
West Ham's first three Premier League games will be played away from home to accommodate the athletics.
How man tickets have been sold?
As of 6 July there had been 230,000 tickets sold, making it the most well attended World Para-athletics Championships in history. There are still tickets remaining should you decide to go.
How can I tune in?
BBC Radio 5 live will be bringing you commentary throughout the 10 days, as will BBC World Service, and there will be live updates on the BBC Sport website and app. You can also watch the action on Channel 4.
How many athletes? How many events?
There will 1,074 athletes competing from 91 nations, with 213 medal events. Great Britain have compiled a 49-strong team.
Who are the big British names?
Jonnie Peacock, the 100m sprint star who won gold at the 2012 and 2016 Paralympics, will look for a second world title.
Hannah Cockroft won three gold medals at Rio 2016 and can repeat the feat in London in the 100m, 400m and 800m. She already has 12 Paralympic and World titles to her name.
Aled Davies and Jo Butterfield dominated the shot put and club throw respectively in Rio and will be expected to do the same again.
Kadeena Cox made a name for herself in Brazil by winning gold on the cycling track and athletics track, and will hope to add a 400m world title to her accomplishments.
Georgie Hermitage, Sophie Hahn, Paul Blake, Richard Whitehead and Hollie Arnold will also hope to replicate their gold-winning success in Rio.
Where's David Weir?
Ten-time Paralympic medallist David Weir was never considered for selection after he withdrew from British Athletics earlier this year because of a fallout with coach Jenni Banks.
He has subsequently retired from track racing to focus on long-distance road racing and made his last competitive appearance last week at the London Anniversary Games.
The absence of Libby Clegg should also be mentioned. Clegg won two sprint golds at Rio 2016 but had to pull out of this summer's event through injury.
Where will GB finish in the medal table?
The British team finished fourth in the medal table at the last World Championships in Doha two years ago. GB had 31 medals, 13 gold, and came behind China, Russia and the US.
GB will match that tally of golds if all of their victorious athletes from Rio 2016 repeat their success.
Russia will not be competing because they remain banned by the International Paralympic Committee following evidence of widespread doping, so GB will expect to move up the table by at least one place.
Remind me how classifications work…
Each athletics event is given a code, made up of one letter and two numbers, which is called a classification. It tells you more about the type of disability the athletes in that event have.
- The first letter will either be T or F: T is for track (running and jumping events) and F is for field (throwing events).
- The first number, from 1 to 5, tells you the impairment type: 1. Visual impairment 2. Intellectual impairment 3. Co-ordination impairment 4. Limb deficiencies and short stature 5. Impaired muscle power or range of movement.
- The second number ranges from 1 to 8 and designates the level of impairment, with 1 being the most impaired.
