What a difference a year makes for Jessica Judd.
Twelve months ago she slumped in a car park in Birmingham and sobbed uncontrollably.
With the Olympics in sight, she suffered a meltdown at the trials, her legs turning to jelly and her world crashing down around her.
Fast forward a year and Judd ran a 4:03.73 personal best to make the semi-finals of the 1500m at the World Championships in London.
The 22-year old - a two-time world medal winner at youth and junior level - was the first British athlete in action and made all the running in her heat.
Reigning champion Genzebe Dibaba and former world gold medalist Caster Semenya finally came through to take the top places while Judd's time qualified her comfortably, promoting a wide and disbelieving smile.
"That was amazing and it felt so, so good," said Judd, who finished second at last month's team trials.
"To get a personal best was fantastic and I've never heard a crowd like that in my life - that's the highlight of my year.
"It was a really stacked heat and I was tenth fastest going in, so I knew that I couldn't hang about and it would be really, really hard to qualify.
"I couldn't hear myself think out there, I normally work out how I'm feeling by listening to my breathing but I couldn't hear a thing.
"I just had to put my head down and charge. As we came down the top straight I realised I'd got into the top six and was even able to ease off a little bit."
Judd will be joined in the semi-finals by team-mates Sarah McDonald, Laura Weightman and medal contender Laura Muir.
Muir is a proven Diamond League campaigner and arrives after setting the British records over 1000m and 1500m this season.
"I'm really happy where I'm at, training has been going really well, so I just want to get through the rounds and conserve as much energy as possible for the final," she said.
Elsewhere, the British trio of CJ Ujah, James Dasaolu and Reece Prescod made light work of their 100m heats, easing through to Saturday’s semi-finals.
It was a simple task, too, for Holly Bradshaw, requiring just one effort to hit the qualifying height in the women’s pole vault.
Bradshaw finished fifth at last summer’s Olympic Games in Rio, but, spurred on by the 55,000 fans who packed out the London Stadium, she sees no reason why this can’t be her time to shine.
“I’m feeling really confident, and like nothing can faze me. I’m so in control of my performance,” she said.
“There are some really good girls who have made the final, so it’s going to be a good battle but I’m definitely going to be up there fighting for one of those medals.”
But elsewhere, it wasn’t to be for discus star Nick Percy, as he bowed out of the World Championships with his effort of 56.93m proving not enough for progression.
