Caster Semenya won her second 800m race in four days following her return to the track after undergoing gender tests - and insisted she can run even faster.The world champion clocked two minutes, 2.41 seconds at the Savo Games in Lapinlahti, her second win in Finland.Semanya, 19, was almost two seconds faster than in Lapinlahti, her first race for 11 months on Thursday."I got what I was looking for but next time I want to run the first 600m faster, in 1:28 or 1:29," said Semenya."This wasn't easier than in Lappeenranta as I had to push hard to the wind in the second lap."Sweden's Sofia Oberg finished in second, while Russia's Anna Verkhovskaya took third place.Semenya will head back to South Africa to continue her training regime before returning to Europe in August for further races.The teenager took the gold medal at the World Championships in Berlin last year but her rapid improvements over the distance prompted speculation over her gender.However, following the completion of their testing procedure, the International Association of Athletics Federations (IAAF) cleared Semenya to compete again last Tuesday.And Semenya has outlined October's Commonwealth Games in Delhi as her next major target.Source: BBC
