Aikines-Aryeetey is ranked as the British number two over 100m

Harry Aikines-Aryeetey kept up his run of good form ahead of the Olympics by winning the 100m at the outdoor season curtain-raiser in Loughborough.

The 19-year-old, who set a personal best of 10.18 seconds in Italy last week, saw off rivals Nick Smith and Ryan Scott with a time of 10.48sec.

Aikines-Aryeetey staked his claim to a spot in Britain's Olympic team saying: "They'll take me seriously now."

Heptathlete Jessica Ennis also found her form to set a new javelin best.

In difficult conditions, Ennis, who will be amongst the medal favourites in Beijing, landed a lifetime best throw of 43.08m.

The 22-year-old will now step up her preparations for Beijing at the Gotzis Hypo multi-event meeting in two weeks' time.

"I'll get a real indication of where I am at," Ennis predicted.

"I jumped 6.03m in the long jump today with a new run-up so it was nice to try that out.

I don't think anyone expected me to do that Harry Aikines-Aryeetey

On clocking 13.59 seconds in the 100m hurdles, she added: "It was a bit of a slow time into a headwind.

"But it was my first hurdle of the season so nice to get a run in."

Aikines-Aryeetey, who won the world junior 100m title in 2006, hopes his performance in Loughborough underlines his claims for selection for this summer's Olympic Games.

The Londoner missed last season with a stress fracture and must now battle Tyrone Edgar, Craig Pickering, Marlon Devonish and Simeon Williamson for the chance to represent Britain.

"It's nice to be back," he said. "Running my first race in 10.1sec, I think kind of shocked a few [rivals].

"I don't think anyone expected me to do that. I suppose it said, 'I'm out to say I'm here'."
