It's not quite a sell-out at the National Athletics Centre, which is basking in the evening sun as the first afternoon session of these World Championships gets under way.
But there's still a great buzz of anticipation around the arena and a mighty roar whips up around the place as the first men's 1500m heat gets under way and continues to follow Jakob Ingebrigtsen and company round the track.
It's warm, up in the high 20s, but very still and perfect conditions for the athletes.
Men's 1500m heats
Jakob Ingebrigtsen, in bright pink shoes, starts off by heading to the back before slowly making his way towards the front over the first lap.
Josh Kerr is currently sitting in fourth.
Men's 1500m heats
Here we go then for the first race of the night.
Olympic champion Jakob Ingebrigtsen - the big favourite in this event - gets a loud cheer from the crowd.
Britain's Josh Kerr is in this heat too.
The top six go through to the semi-finals.
Heat 1: Jakob Ingebrigtsen, GB's Josh Kerr
Heat 2: GB's Neil Gourley
Heat 4: GB's Elliot Giles, US record holder Yared Nuguse
Men's 1500m heats

He is attempting the 1500m-5,000m double - a year after being a surprise second behind Britain's Jake Wightman in Eugene.
Ingebrigsten ran three minutes 27.14 seconds earlier this year which makes him the fourth-fastest 1500m runner in history.
Hicham El Guerrouj's iconic 3:26.00 world record has stood since 1998. Could it go this week?
Ingebrigtsen goes in the first heat at 18:02 BST.

Budapest’s new National Athletics Centre is a fitting arena for the world’s best athletes to deliver world-class performances.
The purpose-built 35,000 capacity stadium is situated on the Danube River, in a former industrial area which was previously inaccessible due to pollution.
It really is spectacular.
Following the event, the plan is to reduce the capacity to 15,000 with the removal of the temporary upper tier, creating a leisure and sport centre for public use.
We were treated to an upbeat opening ceremony before the start of the evening session. Plenty of tunes, an air show, and a display of flags representing every nation present at these World Championships.
The biggest cheer so far was reserved for the mascot, Youhuu, a native Hungarian racka sheep (as you suspected) who has just run the slowest 100m we’re likely to see this evening to great applause.

London 2012 Olympic heptathlon champion on BBC TV
Katarina Johnson-Thompson started off in the hurdles ok, it probably wasn't what she wanted. Kat didn't have that speed or endurance to maintain. It's good to see her come out and run that sort of time. Again, not at her best.
Katarina Johnson-Thompson has her shot put in hand and is just going through a few warm-ups.
Just a reminder the heptathlon gets back under way just after 18:00 BST.

Since winning her world title four years ago Johnson-Thompson has endured several injury setbacks and even feared her career might be over after rupturing her Achilles.
But a beaming smile on the 30-year-old's face as she found her rhythm in the high jump during the morning session spoke volumes of her current outlook.
And so she should be smiling. After two events, she is absolutely in medal contention.
Next up is the shot put, certainly not her favourite event, but she did throw a personal best 13.92m earlier this year and she’ll hope to replicate that performance here before giving her all in the 200m.

We've already had some action on the opening day.
In the first session Katarina Johnson-Thompson made a decent start to the heptathlon.
The 2019 champion had a slightly disappointing 100m hurdles but a good performance in the long jump left her fourth overall.
Laura Muir, Katie Snowden and Melissa Courtney-Bryant all progressed in the 1500m, along with big name Faith Kipyegon and Sifan Hassan.
Britain's 4x400m mixed relay team were the second-fastest qualifiers for tonight's final but Jazmin Sawyers failed to make the long jump final.

The weather was certainly not playing ball this morning as Budapest prepared to kick off the biggest sporting occasion in Hungary’s history.
Those in the city woke to dark, threatening clouds - although that did not dissuade these fans from Finland from a bit of early sightseeing.
We had the odd rumble of thunder before the heavens opened, delaying the opening event - the men’s 20km race walk - and morning track session by one hour.
The adverse weather conditions would not dampen the mood and in a well-attended morning session the heptathletes eventually got the action under way at the National Athletics Centre.
The excitement and anticipation has been building here for some time and, now that we're up and running, it feels as though we could be in for a memorable nine days of competition.
