Katarina Johnson-Thompson, Great Britain's heptathlon hope in the absence of the injured Jessica Ennis-Hill, got her World Championships off to a promising start in Moscow.
The 20-year-old clocked 13.49 in the 100 metres hurdles, just 0.01 outside her personal best, and followed it up with a clearance of 1.83m in the high jump, narrowly down on her season's best.
That put her in fourth place on 2068 points, 24 off third, with Ukraine's Ganna Melnichenko leading on 2135.
Johnson-Thompson had said in the build-up she felt under no pressure, despite the withdrawal of Olympic champion Ennis-Hill leaving her in the spotlight.
She claimed experiencing London 2012 as a teenager had prepared her for anything.
The Liverpool athlete was bowled over by the noise which greeted her introduction to the crowd last summer, mouthing "wow" as she smiled the biggest grin in the stadium.
But on Monday morning there was quite a contrast, with barely 500 spectators in the Luzhniki Stadium to watch her.
Undeterred, Johnson-Thompson got her campaign off to a good start.
Ennis-Hill wished her all the best, writing on Twitter: "So strange not to be out there at the worlds! Wishing @JohnsonThompson lots of luck though. Good start :)."
Meanwhile, Perri Shakes-Drayton demonstrated her medal credentials in the women's 400m hurdles with a confident run, pulling comfortably clear of defending champion Lashinda Demus of the United States and Russia's Olympic gold medallist Natalya Antyukh.
The Londoner won her heat in 54.42 to progress as easily the fastest qualifier.
But her rival for the gold, Czech Zuzana Hejnova, also looked impressive, able to slow to a jog metres from the line such was her lead to win in 55.25.
Shakes-Drayton is aiming to make up for the agony on missing out on a place in the Olympic final in her home city by following in the footsteps of Sally Gunnell and taking the world crown.
She said: "It felt good, it was relief - I'm through without anything happening. I knew I was more than capable of making it through, but it's just pure relief.
"I just need to rest and recover properly and tomorrow's another day."
Scotland's Eilidh Child, also enjoying the season of her life, went through to the semi-finals after finishing second in her heat in 55.17, and Meghan Beesley made it a full contingent in the next round by also coming second in 55.45.
