Olympic star Caster Semenya says she is not worried about world records, only a gold medal.

The South African women’s 800m favourite was expected to cruise into Saturday’s final after racing in the last night’s semifinal.

After cruising through the heats with a time of 1:59.31, Caster is expected to put her foot on the accelerator now.

The Limpopo-born star boasts a season’s best of 1:55.33, which is also the fastest time by any woman since 2008.

The Olympic record (from Moscow 1980) sits at 1:53.53, with the 33-year-old world record at 1:53.28.

But Semenya is only focused on finishing first.

She says: “I’m not focused on the records, I’m just focused more on enjoying my championship. Times don’t matter in championships.

“What matters is a gold medal, silver or bronze, so we don’t worry about times at the moment.”
