Spalding youngster Rosie Fresen soared to a Nene Valley Harrier indoor pole vault record at Lea Valley on Sunday.
The teenager only began training for the pole vault recently after filling in to score points in the league last summer.
She has taken to the event like a duck to water and cleared 2.50m when lining up in the under-17 women’s age group at the Metaswitch Indoor open meeting on Sunday, and she was unlucky to fail at the next height.
Another under-17, Bourne teenager Megan Pusey, also recorded an indoor personal best with a time of 28.94 in the 200m.
Earlier in the day, Pusey had competed in the two rounds of the 60m – recording times of 8.78 and 8.68, which was just eight-hundredths of a second from her personal best.
The first round caught her off guard with some very fast starters but the Nene Valley athlete, competing in the event as a sharpener for the longer sprints, was not fazed and she won her heat in the second round.
Fellow Bourne athlete Jasmine Allen jumped 4.52m in the under-15 girls long jump, finishing third overall.
She showed a good improvement from her first event at Sheffield just two weeks earlier and recorded her second best ever indoor jump.
Allen also competed in the 200m, recording a time of 28.74 as she used the event as a sharpener for the championships being held early next year.
Bourne Town Harrier Cameron Everist won the junior race at the Frostbite Friendly League at Hinchingbrooke Park, Huntingdon, on Sunday.
He won by seven seconds in 9.25 with local youngster Nathan Davey finishing fifth for Nene Valley Harriers in 9.51.
Jonathan Palmer was the leading local in the senior race, the Bourne Town Harrier finishing tenth in 30.40.
Despite his efforts over the five-mile course, Bourne finished last of the 16 teams and remain bottom of the league after three of the six races.
Nene Valley Harriers won on the day and now hold a one-point lead over Hunts Athletic Club.
Nene Valley also lead the junior league, where Bourne Town Harriers are in eighth place, having finished sixth on Sunday.
