Two golds and a star performance were the highlights for City of Norwich Athletic Club at the indoor calendar's top event.

The Aviva England Athletics Open Under-20, Under-17 and Under-15 Indoor Championships held at the National Indoor Arena, Birmingham, is the highlight of the indoor season.

This year's event saw a plethora of records fall during the two days at the end of February, while eight CoNAC members took part in disciplines ranging from sprints, jumps and throws.

But it was the final race that produced the performance of the championships.

The under-15 boys' 400m heats had already seen Norwich's Aaron Pitt, a relative newcomer to the event, storm the first lap of his heats so hard he had a 15m lead, before easing off to win through.

The final saw Pitt amaze the crowd with a fantastic sprint from the start, finishing 2.58 ahead of his nearest rival and recording an unbelievable 51.01 to take gold. It was the second fastest time ever run in the UK for the age group.

Katie Vickery had started proceedings off in the under-15 girls' long jump, where she finished sixth (4.79m).

She also managed a good run of 8.5sec in the 60m sprint heats later in the day. Ellie Blunt, in the same event, ran a new personal best of 8.13 with Ella Stephenson stopping the clock at 8.2 in the heats and achieving a new PB in the semi-final with 8.13.

In the under-17 women's 60m Victoria Mitchell turned in 8.5 with fellow team-mate Clieo Stephenson passing through the heats and semi-final, equalling her lifetime best of 7.88 in both.

She then took fourth in an extremely close final, in 7.91.

Clieo narrowly missed out on a bronze medal after officials consulted the photo finish in what was a fantastic final.

The second day of the competition started with Clieo, this time competing in the under-17 women's 200m semis - one complete lap of the banked indoor oval circuit.

Clieo acquitted herself well running 25.75 against the backdrop of running three 60m races the previous day - but she just missed out on the final's qualifying time.

Laura McDonald competing in only her second under-17 triple jump competition managed 11.17m with her first jump to take silver, and CoNAC's first medal at the championships.

Sophie McKinna, who competes for Great Yarmouth AC, closely watched by her coach Jeff Capes and boosted by her success earlier this year at the Southern Indoor Championships, threw a colossal 13.24m in the under-17 women's shot to take a well deserved gold to give CoNAC even more success to celebrate.
