CAPE TOWN - Caster Semenya is back to her best following a sensational performance at the Athletics South Africa (ASA) senior track and field championships in Stellenbosch on Saturday.

The Olympic silver medalist won the women's 400, 800 and 1,500 metre titles, the first athlete in South African history to win those three races at the same event.

Semenya says running in Stellenbosch feels like home.

"This is like my home ground, my first national title. I came here when I was 18 years old, so obviously when I run here I feel at home. So it's one of my second homes. I love the crowd, I love performing for them, it's more like giving back."

While it all went her way with comfortable victories in the shorter events, Semenya faced a strong challenge from US-based athlete Dominique Scott in the metric mile.

Scott took the lead on the first lap, but Semenya took advantage of a relatively slow early pace to launch her trademark kick over the last 200m as she drew clear, becoming the first athlete in the history of the annual Championships to win all three titles.

"I appreciate every achievement that comes my way, and obviously now it's up to me to improve myself for the rest of the year," Van Niekerk said.

He said, "The main goal is the Olympics, and I'd like to pick up a bit more momentum before I get to Europe and then Rio."
