It has been a long season but now it is finally time for the IAAF World Championships.

When speaking to athletes during the course of this year, a recurring theme has been the balancing act involved in peaking for a moment which falls significantly later in the calendar than usual. It is a difficult trick to pull off but it would appear many have managed to do it. The recent Diamond League finals were evidence of that and there are rivalries and contests to savour right across the coming days of competition in Doha.

Here we take a day-by-day look through the world championships schedule:

Day one – Friday September 27

16:30 (14:30) M Long jump – Qualification

16:35 (14:35) M 100m – Preliminary round

The first medals of the championships will be claimed in the women’s ‘midnight’ marathon, which starts at 23:59 local time to try and avoid the worst of the heat out on the roads of Doha. “The overwhelming thrust of this is the welfare of the athletes,” said IAAF president Seb Coe in the pre-event press conference. “We are monitoring this very closely.”

Bahrain’s Rose Chelimo defends her title and goes up against athletes including Kenya’s two-time winner Edna Kiplagat. Britain is represented by Tish Jones and Charlotte Purdue.

There are six titles to be won on day two, including in the men’s 100m and women’s 10,000m.

The women’s hammer and men’s long jump are up first, with Luvo Manyonga defending his title against world indoor champion Juan Miguel Echevarria, before the women’s 10,000m, which will not feature Britain’s Eilish McColgan after she chose to contest only the 5000m in Doha. Steph Twell will be pulling on the GB vest as she races over 25 laps of the track before switching her attention to the Frankfurt Marathon.

British champion Ojie Edoburun is joined by Adam Gemili and Zharnel Hughes – who are both entered for the 100m, 200m and 4x100m triple in Doha – for the shorter of the sprint events. USA’s Christian Coleman leads the world rankings with 9.81.

Again, to avoid the worst of the heat, the two 50km race walk events start at 23:30 local time, with Cameron Corbishley and Dominic King in action for GB.

Day three sees five finals take place. After qualification on Friday evening, British record-holder Holly Bradshaw could be among those going for the medals in the women’s pole vault in what she believes to be one of the most open ever competitions.

The men’s triple jump is set to see USA’s Christian Taylor and Will Claye fight for victory and behind them there looks to be another battle for bronze. Britain’s Ben Williams believes he will be among those fighting for a medal in a season which has seen him add 53cm to his personal best.

The final of the inaugural world mixed 4x400m relay takes place, while Britain’s Dina Asher-Smith could claim a first of three medals as she targets the 100m, 200m and 4x100m triple in Doha. Double Olympic champion Elaine Thompson and multiple global medallist Shelly-Ann Fraser-Pryce of Jamaica are among her competition.

Road action continues with the women’s 20km race walk.

Authorised neutral athlete Mariya Lasitskene hopes to become the first three-time world high jump champion but faces competition from Ukraine’s Yuliya Levchenko. Morgan Lake jumps for GB.

Doha will offer the first world 5000m final since 2005 without Britain’s 10-time global gold medallist Mo Farah. All three Ingebrigtsen brothers – Henrik, Filip and Jakob – are entered, while Britain’s team includes Andrew Butchart, Ben Connor and Marc Scott.

The women’s steeplechase features Kenya’s world record-holder Beatrice Chepkoech and three British athletes – Elizabeth Bird, Rosie Clarke and Aimee Pratt.

South Africa’s three-time world champion Caster Semenya will not race for a fourth 800m gold following the IAAF’s new rules on female classification. USA’s Ajee’ Wilson leads the entries with 1:57.72, with Brits Alexandra Bell, Shelayna Oskan-Clarke and Lynsey Sharp hoping to be in action, should all have gone to plan in the earlier stages.

The men’s 400m hurdles is one of the most highly-anticipated events of the championships and the final takes place on day four, where defending champion Karsten Warholm, who sits second on the world all-time list, will likely go up against two other athletes who join him in the top four on the global all-time rankings – Rai Benjamin and home favourite Abderrahman Samba.

Nijel Amos stormed to the top of the world 800m rankings with his 1:41.89 in Monaco for the fastest time recorded since the London 2012 Olympics. USA’s Donavan Brazier will be another one to watch and British athletes Elliot Giles, Kyle Langford and Jamie Webb will be looking to make the final.

What will Noah Lyles do in Doha? The American clocked 19.50 at the IAAF Diamond League meet in Lausanne and seeks a first senior global title. Also in 200m action in Doha are Britain’s Miguel Francis, Adam Gemili and Zharnel Hughes, with Francis having clocked 19.97 this year and British champion Gemili and European 100m champion Hughes hoping to be back in action after racing the 100m.
