The IAAF World Championships begin tonight as athletics returns to the Olympic Stadium, home of the 2012 Olympic Games.
All the live action from the competition will be shown on BBC One and BBC Two, with a highlights programme covering the major talking points on BBC Two each evening.
Two years ago the British team came away with seven medals from the World Championships in Beijing, four of which were gold.
This time around, a total of 87 athletes have been chosen to don the British colours - the largest ever team to represent British Athletics at a World Championships.
Here are five of those to keep an eye out for.
With four Olympic golds and five World Championship titles to his name, London 2017 could be the icing on the cake for Mo Farah as his track career nears its end.
One of the British team's brightest hopes, Farah will return to the stadium where he produced two of the stand-out moments of London 2012.
The 34-year-old is aiming for the treble double, gold in the 5000m and 10000m at three successive World Championships.
Farah’s first medal at the World Championships was a silver in the 10000m in Daegu six years ago, but since then he has only dealt in gold, claiming the 5000m title four days later.
This time around, the most decorated athlete in British athleticshistory will take to the track at 21.20 tonight for the 10000m final, before the 5000m heats on Wednesday night.
Muir is tipped to become the new face of British athletics and is a major contender in the 1500m and 5000m.
The 24-year-old will take to the track in the 1500m heats at 19.35 this evening, with the final on Monday night.
The Scot will be looking to improve upon her seventh-place finish in this event in Rio.
And she comes into the World Championships full of confidence after taking gold in the 1500m and 3000m at the European Indoors in Belgrade earlier this year.
As for the 5000m, we must wait until Thursday evening to see Muir in the heats before the final, also in the evening, the following Sunday.
Fresh from smashing the one-mile walk world record in five minutes 31.08 seconds at the Anniversary Games, Bosworth returns to London seeking World Championship success.
This month, the 27-year-old will compete over 20km, after coming sixth in the event at the Rio Olympics.
But the Anniversary Games were a taste of what Bosworth can do with the home crowd behind him, so expect him to feature highly.
Liverpudlian Katarina Johnson-Thompson has said she has fallen back in love with the heptathlon after a difficult few years which saw her finish sixth in the Olympics and 28th in the World Championships after three fouls in the long jump.
Having moved to Montpellier to train, the 24-year-old is targeting her first senior global medal in the heptathlon, having achieved a personal best score in May this year.
Johnson-Thompson’s seven events will take place across the weekend, with the 100m hurdles first up on Saturday at 10.05.
Asher-Smith returns to London Stadium as Britain’s fastest woman, having carried the athletes’ kit on Super Saturday five years ago.
There was doubt as to whether the 21-year-old would make it to the World Championships after she broke her foot in February, but she battled through to prove her fitness.
The Londoner was the first British woman to run under 11 seconds and won Olympic bronze as part of the 4x100m relay team last summer.
Heats for the women’s 200m will begin at 19:30 on Tuesday, there will then be semi-finals on Thursday before the final on Friday night.
