Berlin, Germany: British heptathlete Katarina Johnson-Thompson enjoyed a small lead over Nafissatou Thiam after two events Thursday as the Belgian sought to add the European crown to her world and Olympic titles in Berlin.
The Briton raced to 13.34sec in the opening 100m hurdles, just four-hundredths off her personal best, while the Belgian could only manage 13.69.
Thiam, whose best of 2.01m was set in May, then recorded three fails at a disappointing 1.94m in the high jump.
That was mirrored by Johnson-Thompson, who set her personal best of 1.98 when finishing sixth in Rio, a position she improved to fifth at the London worlds before winning golds at the Commonwealths and also at the World indoors pentathlon in Birmingham in March.
With the the shot put and 200 metres to come later Thursday, Johnson-Thompson has racked up 2,193 points, a lead of 51 over Thiam. The heptathletes will also compete in the long jump, javelin and 800m on Friday.
In track qualifiers Thursday, France's 800m world champion Pierre-Ambroise Bosse safely negotiated his heat to advance to Friday's semi-finals, with the final to be raced on Saturday.
Double defending champion Adam Kszczot of Poland also made sure of his progress in a bid to emulate the three gold medal showing by his teammates in the field.
Thursday's evening session sees six events in which medals are up for grabs: the 200m, 400m hurdles, 3000m steeplechase and javelin for the men; the 100m hurdles and pole vault for the women.
- Mekhissi going for gold -
France's three-time Olympic medallist Mahiedine Mekhissi, who is gunning for an audacious double in Berlin, could make history when he takes to the track for the steeplechase.
The 33-year-old has already won the steeple three times (2010, 2012, 2016) and the 1500m once (2014) and should he win the steeple would take over from sprinter Christophe Lemaitre as the French athletes with the most golds on the European stage.
He would also join the trio of German Harald Schmid and British pair Roger Black and Mo Farah, the sole athletes to have won five golds.
On Saturday, Mekhissi runs again, in the 5000m this time, but he insists he remains focused first on the steeplechase.
"It's not going to be simple even when you're favourite," he said.
"When you're the number one, you're expected and other athletes aren't just going to let you run and get the victory. It's up to me to work myself and go looking for that title."
Mekhissi added: "You might think that with four European titles, I have less hunger, but me, I'm always hungry for more, I always want to run.
"That's why I'm here and why I train. I don't take part in major championships just to take part. If I run, it's to perform, to shine and win medals for the France team and myself. That's what stimulated me, to do what others have never done."
