Katarina Johnson-Thompson won the heptathlon at the Gotzis Hypo-Meeting with a personal best and world-leading score of 6,813 points.
The 26-year-old Briton extended her overnight lead by leaping the furthest in the long jump – 6.68m.
She also performed strongly in the 800m to finish ahead of second-placed Latvian Laura Ikarniece (6,476) and Xeria Krizsan of Hungary (6,469).
Her previous best score was 6,759 as she won European silver last year.
After the long jump, the Commonwealth champion’s javelin throw of 42.92m and second-best time of 2mins 8.28secs in the 800m were enough to secure the best heptathlon score of the season so far.
Having been sixth overnight, fellow Briton Tim Duckworth finished 17th in the decathlon with 7,981 points, as Canada’s Damian Warner (8,711) won ahead of Grenada’s Commonwealth champion Lindon Victor (8,473).
Duckworth’s most impressive mark of the day was 4.90m in the pole vault, keeping him seventh after eight events, but he drifted with a 1500m time of 4 mins 57.65secs in the final event.
After day one of the annual event in Austria, Johnson-Thompson led with 4,034 points having gone highest in the high jump before claiming the quickest 200m time.
The competition in Gotzis is considered the biggest combined event outside of the major championships and attracts many of the world’s best multi-eventers.
Johnson-Thompson’s compatriot Niamh Emerson, 20, was forced to withdraw after two events on day one following the recurrence of a knee injury.
