Birthday celebrations started early for Hercules Wimbledon’s sprinter Rechmial Miller when he clinched his place in the IAAF World Junior Championships at the Bedford International Stadium on Saturday.

Eight days before he turned 18, Miller secured his call-up by taking the junior men’s 100m title in 10.47 seconds running into a 0.8mps headwind.

Earlier, he won his heat with the backing of a forceful 3.3mps headwind in 10.43secs, easily the fastest of the 42 runners taking part to set himself up as favourite to take gold.

The wind dropped slightly for his semi-final to 2.6mps and he again posted a comfortable win in 10.45secs, again the fastest time of the 23 semi-finalists.

Miller did not disappoint in the final which he won by a comfortable five-hundredths of a second - about half-a-metre - to clinch his place in the team for Poland.

The IAAF World Junior Championships are held in Bydgoszcz from July 20.

Teenager Miller, who won silver and bronze medals, respectively, at last year’s Commonwealth Youth Games and IAAF World Youth Championships said: “I’m obviously very pleased to have made the team.

"It’s been my main target for this season. I now hope to run faster than ever in Poland.”

Miller is Britain’s top U20 100m runner this season, with his 10.34secs clocking in the Loughborough International meeting in May.

That time took five-hundredths of a second off his previous legal life-time best for the distance set when racing to silver in the Commonwealth Youth Games in Samoa last September, although he did clock a wind-assisted 10.35secs at the Bedford International Games in May last year.

At the other end of the age range, Hercules Wimbledon’s men’s veterans team looks set to reach the Southern Veterans League final for the first time in their history.

They have a comfortable lead in the South London division after winning their third match at Wimbledon Park.

The team was just beaten in their opening match at Kingsmeadow, but secured victory in their second encounter at Ewell Court.

The win was underpinned by a trio of club age records and a host of winners.

Dean Cheeseman gained a double success in the over-35 high jump and triple jump while Mike Amsden won the 200m in that age group.

He then linked up with Vic Ray, Dominic Bokor-Ingram and Mark White to win the 4x200m relay.

Bogor-Ingram and White also won the over-40 and over-50 200m events.

Other over-40 winners were Stephen McDuell (800m) and Stuart Fraser (5,000m). Charles Laurie took the over-60 triple jump while Peter Giles broke the club age record in winning the over-70 800m.
