(CNN) -- World champion Caster Semenya raced to her second 800 meter victory in four days following her return from an 11-month absence to undergo gender tests.
The South African athlete won in two minutes, 2.41 seconds at the Savo Games in Lapinlahti, Finland, two seconds faster than the time she produced in her comeback race in the same country last Thursday.
"I am very pleased with my performance," the 19-year-old told AFP. "I got what I was looking for, but next time I want to run the first 600m faster, in 1:28 or 1:29.
"I don't know where my next race will take place. Now I'll fly back home and start to train harder."
Semenya emerged from obscurity at the beginning of last year to run world class times over 800 meters, culminating in victory over the distance in the world championships in Berlin in August.
Her runaway gold medal performance in one minute, 55.45 seconds raised eyebrows and the International Association of Athletics Federation (IAAF) announced at the championships that they would be conducting tests to determine her gender.
Earlier this month, the IAAF gave her the all-clear to run again as a woman.
Semenya is now targeting a gold medal in October's Commonwealth Games in Delhi.
