Jessica Ennis-Hill has claimed that she has a "feeling of slight disappointment" after her day-one performance at the World Athletics Championships heptathlon in Beijing.
The Briton, competing in her first international championship since London 2012, has a 60-point lead on Katarina Johnson-Thompson following the first three events.
However, Ennis-Hill has suggested that her results could have been a little bit better.
Ennis-Hill told BBC Sport: "I am pleased. I have that feeling of slight disappointment because I'm always comparing myself to my best.
"Generally, I'm really happy to be in this position right now."
Both Johnson-Thompson and Ennis-Hill produced season-best times in the 200m, finishing one-two.
