World Athletics Championship 2017: Day One



Evening folks! Today marks 5 years since the start of the 2012 London Olympics, and this week many of that summer's biggest stars return to the Olympic Stadium. It's @hannakin__ here with live coverage of Day One of the 2017 World Athletics Championships.

Tonight is the beginning of the end for two of 2012's biggest stars - Mo Farah will look to defend his 10,000m title, whilst Usain Bolt will run a bit later on in the 100m heats. The other main action from tonight comes in the form of the the Women's 1,500m heats, where Britain's Laura Muir will begin her quest for gold.

Field action this evening includes Men's discus and long jump qualifying, and Women's pole vault qualifying.

We'll keep you abreast of all the action tonight, but here are some of the key times: 19:35 - Genzebe Dibaba and Caster Semenya in 1,500m heat #1 19:45 - Holly Bradshaw in Pole Vault qualifying group #1 19:48 - Laura Muir in 1,500m heat #2 21:00 - Usain Bolt in the 100m heat #6 21:20 - Mo Farah in the 10,000m final

Already underway are the Men's 100m preliminary races. Top #3 from each of the four races go through as well as 2 fastest losers. Fastest qualifier after two races is Turkey's Emre Zafer Barnes with 10.22. Sitting in the 2nd fastest loser spot at the moment is Dyland Sicabo of the Seychelles with 11.01.

Last two races considerably faster than the first two, no DQs by the looks of things. And a National Record already this evening! Slovakia's 100m record broken by Jan Volko, winner of the 3rd heat with 10.15.

Right then, 100m prelims finished, that National Record of 10.15 survives as the fastest qualifying time. Fastest losers both coming from that final race, Comoros' Ambdoul Karim Riffayn with a 10.59 and Cameroon's Jean Tarcicius Batambok with a 10.71.

Up next on the track are the 1,500m heats, 6 fastest from each race qualify automatically, with 6 fastest loser spots up for grabs. First race just about to get underway, WR holder Genzebe Dibaba goes in this one, as well as 800m olympic champion Caster Semenya, and Brit hope Jessica Judd.

Jessica Judd leading things out on this first lap, Dibaba just took a look down the back straight of the second lap and now starting to move up as the begin they penultimate lap.

Judd clearly taking some encouragement from the crowd, continuing to stretch things out from the front, Dibaba on her heels and a bit of a gap forming between them and the main pack as they hear the bell.
