Evergreen Dartford shot putt star Scott Rider continued his preparation for next month's Commonwealth Games by winning the British Championships in Birmingham for the first time this weekend.

Rider will represent England in Glasgow, having finished in the top-10 in the previous two games in Melbourne and Delhi.

The 36-year-old - runner-up in the British Championships in 2010, 2011 and 2012 and who finished third in 2008, finally topped the podium with a throw of 18.34m to make it two wins and a second in three competitions so far this season.

There was also medal glory for two more Kent athletes.

Sprint sensation Adam Gemili is also preparing for the Commonwealth Games, but the World Championship 200m finalist in Moscow last summer had to settle for second place in the event in Birmingham on Saturday.

Having cruised through his heat, winning in 20.71secs, the Dartford star, 20, who runs for Blackheath & Bromley AC, finished the final in 20.61, 0.19secs behind champion Danny Talbot and almost two-thirds of a second off his own Personal Best.

In-form Tonbridge AC race-walker Tom Bosworth set a superb new national record in the 5,000m walk.

The 24-year-old set a blistering new best time of 19:16.82 - smashing his PB, set at the event last year, by 22 seconds - to claim second in the race, behind Australian guest Dane Bird-Smith, but taking the British title.

Tonbridge AC clubmate Guy Thomas was seventh in the same race in 23:21.

Gillingham throwing star Shaunagh Brown is also heading to Glasgow next month.

The Blackheath & Bromley AC star, 24, could only finish 10th in the hammer, in which she will represent England, 10m short of the PB she set two weeks earlier, with 56.09m.

However she was only one place outside the medals in the shot putt, finishing fourth with a throw of 15.46m.

Glasgow-bound Orpington long-jumper Lorraine Ugen was fourth with a best leap of 6.38m, Deborah Martin of Ashford AC was eighth in the high jump final with a clearance of 1.74m while Medway & Maidstone AC sprinter Andre Wright finished third in the semi-finals of the 100m in 10.44secs.
