World Record - Heptathlon - WIC 2012
There was no such concern for Ennis-Hill, although she failed to reach the heights she might have expected, throwing a best of 13.86m in a consistent series that could best be described as solid if unspectacular.
The second-fastest athlete in Britain over 200m this season, Johnson-Thompson somewhat redeemed herself by living up to her billing as the quickest heptathlete in the field to triumph in 23.27sec for a much-needed points boost to end the day.
Ennis-Hill was just metres behind her team-mate, crossing the line in 23.49sec as Thiam felt the full force of her lack of pace, slipping from top of the leaderboard with a pedestrian time of 25.10sec.
All of which meant that, once the complicated calculations had been made, Ennis-Hill was ensured that familiar viewpoint from first place overnight looking down at her rivals.
Top of the standings with a points tally of 4057, the reigning champion may be 101 points down on her score at the same stage during London 2012, but she will start the second day with a significant 72-point lead over second-placed Thiam.
Akela Jones, of Barbados, will resume in third, with Johnson-Thompson knowing she must overturn a 100-point margin on her British compatriot if she is to s****h the gold medal away from her.
