Cape Town - Middle-distance runner Dominique Scott-Efurd broke another national indoor record, while Derrick Mokaleng and Carina Horn also smashed South African sprint marks, as local athletes continued to build on their fine early-season form this week.
Scott-Efurd crossed the line in fourth position in the 1 500m women's race at the fourth leg of the IAAF World Indoor Tour Series in Boston, USA on Saturday evening, covering the distance in 4:07.25*.
Scott-Efurd took a massive chunk off her own previous mark of 4:10.90 which she had set in New York in February last year.
On Friday night, Mokaleng broke new ground by crossing the line in 45.76* to win a collegiate 400m race in Lubbock, USA.
The 20-year-old athlete broke his own national standard of 46.25 which he had clocked in Albuquerque last month.
On Thursday, Horn stormed across the line in second position in 7.10* in the 60m women's race at a meeting in Eaubonne, France.
After knocking on the door the last few years, Horn shattered the 19-year-old national record of 7.15 which had been held by Wendy Hartman.
