Bourne athlete Emma Hornsby broke the Nene Valley Harriers heptathlon club record when finishing 11th in the English Under-20 Multi-Events Championships at Bedford.
The 17-year-old, who had previously set the under-15 pentathlon record, scored 3,859 points on her first attempt at the seven-discipline event.
Hornsby, ranked fifth in the country in the under-17 pentathlon last year, has been in fine form this season and the Bourne Grammar School pupil recorded a sprint double at the Lincolnshire championships last month.
She began at Bedford with third place in her heat of the 100m hurdles, clocking 17.21, and then went within a centimetre of her high jump personal best with 1.57m.
A first-time clearance at that height brought hope of a new best but she was unable to get over the bar at 1.60m.
A third round effort of 8.11m in the shot was followed by a personal best of 26.77 in the 200m, where she won her heat by more than a second.
A second round effort of 5.23m in the long jump got her off to a solid start on the second day and she then threw 16.95m with her final effort in the javelin, having begun with two no throws.
She ended the championships with second place in her 800m heat, clocking 2:38.24.
