Sophie McKinna lit up the Norfolk AAA Championships at Lynnsport, King's Lynn, with a new British record at under-17 level in the shot putt.

The Great Yarmouth athlete recorded a throw of 15m 71 to beat the British record, with her effort having to be remeasured by officials for record purposes. She also had a narrow foul of more than 16 metres.

There is surely more to come from the Geoff Capes-coached athlete as her sights are set on the World Youth Games in July.

That throw leaves her at least two metres clear of the next best thrower in the country.

Another to top the national rankings was hammer thrower Callum Brown.

He threw a tremendous distance of 68m 21 and he will also set his sights on international honours later in the season.

This was outstanding throwing for so early in the season. In fact the cool breezy conditions were no encouragement at all to the athletes, but that didn't hold back the throwers at all.

Michael Painter was another thrower to top the rankings with an excellent throw of 63 metres in the under 17 age group and, just for good measure, he also took the shot and discus titles, in the latter event he threw an excellent 45m 21.

It was good to see King's Lynn girl Emma Tilbrook back to form after a season ruined by injury last year.

Winning several events, her best performance came in the under 17 long jump with a distance of 5m 49.

Gemma Vickery was yet another hammer thrower in form as she threw 34m 81 in the under 17 girls event.

Clearly performances on the track were affected by the conditions.

Perhaps the best performance here came from Clieo Stephenson a 25.7 seconds time in the under 17 200m. She also won the 100m.

Karen Hindle from Diss won the 100m, 200m and 400m in the veterans category. Carol Filer had a fine long jump of 4m 67 in the veterans section.

While there were large, enthusiastic fields in the younger age groups, there was a distinct lack of competitors in the women's section.

The second day of the Norfolk championships will be on June 26 at Sportspark in Norwich where there should be some very good javelin throwing as well as the 1500m events.

The contingent of Norfolk athletes currently studying in the USA are producing more excellent performances.

James McLachlan, last year's English Schools long jump champion jumped 7m 63 in Indianapolis. Britain's best jumpers such as Greg Rutherford had better be wary.
