Ohuruogu, who pulled out of a race in Italy last week with a sore throat, runs in Norway tomorrow and the UK trials in Birmingham next week.

At the Bislet Games in Oslo she will face Sanya Richards, her biggest rival for world gold in Berlin in August.

“I’ve got my voice back for a busy couple of weeks, with Norway and the UK trials,” the Londoner told BBC Sport.

“I hear Sanya will be there in Oslo so it should be a good race.

“But I focus on myself purely because I don’t really have any extra energy to focus on anyone else.”

American Richards, who took Olympic bronze behind Ohuruogu in Beijing, won the opening event of the six Golden League meetings in Berlin a fortnight ago.

But Ohuruogu, 25, has her sights set clearly on arriving in her best shape at the World Championships.
“It’s great to have the Golden League and I’m hoping to do as many as I can this year, but the trials and domestic races have to come first,” she said.

“We don’t want to do too much. The championships are what I work towards.”

“It’s important that I go out and run well. Obviously I want to do well but I don’t hang medals around my neck before I get to championships.

Ohuruogu was speaking at an Aviva UKA Academy training session for local competition winners aged eight to 15 at her home track, the Lee Valley Athletics Centre.

“Just turning up and giving kids a five-minute talk is something I try to make time for,” she continued.
“We athletes who are running now are not going to last forever. We need to encourage and support the youngsters coming up.”

Ohuruogu, who lives in Newham, is already excited about the prospect of the Olympics coming to London in 2012, even though she has not given much thought to taking part.

“Everywhere you go in East London you’re constantly reminded of the Olympics.

“Even though they see the stadium I don’t think people really know what’s there but I do feel they’re excited about it and just waiting to see what it will be like when it arrives, not thinking so much about competing. I’m excited that people get to experience the biggest sporting spectacle ever and it’s coming to my hometown.”
