Belgrave Harriers Dwain Chambers felt his two 60m races at British Indoor Grand Prix meeting last Saturday was good preparation for next month’s IAAF World Indoor Championships.

The 35-year-old former indoor world champion clocked 6.55secs in the preliminaries, then posted 6.66 in the final at National Indoor Arena, Birmingham, where he finished fourth behind his in-form domestic rival from Croydon, James Dasaolu.

Dasaolu suffered a thigh strain injury immediately after crossing the line first in 6.50 and is set to miss the world indoors in the Polish seaside resort of Sopot.

“The two races I’ve had here have been good so were the times,” said Chambers.

“I haven’t been in this type of competition for a while so it’s good preparation for Poland.

“I’m getting faster. That’s the second fastest time I’ve ran in a few years so it shows that it’s still there but I’ve still got some work to do.

“Hopefully there’s some other races I can get into before Sopot to help me improve.”

And Chambers was beaten by Dasaolu for the fourth time this season but says his rivalry with the Croydon sprint sensation is good for athletics in this country.

He said: “It’s healthy competition. It’s good for us, good for me, good for him, good for the country, it’s all great.”
