Reuben Schoeman pipped defending champion Abdhul Malick Railoun by three seconds to take the men’s title in 37min 52sec, with Brandon Isemonger third in 38:09.
“I didn’t expect to win, to be honest. It was a pretty good race overall and I’m very happy with the way things turned out,” said Schoeman.
The 15-year-old also went on to take the double after winning the 1 500m in the men’s 14-30 age group in a time of 17:58.
The women’s 3 000m race concluded just a second after Railoun emerged from the water, with 16-year-old Carmen le Roux winning in 37:53, three seconds ahead of her 18-year-old sister Clarice. Michelle Weber followed in 37:59, ensuring that the top three women finished in the overall top five.
“I knew it was going to be tough coming up against my sister and Michelle, but I was hoping to get the win,” said Carmen, who is, like Schoeman, coached by Alisdair Hatfield at Action Swim Academy in Durban.
Weber did get her revenge in the 1 500m women’s 14-30 age group race by holding off the Le Roux sisters to win in a time of 18:27.
