The 23-year-old Nyahora crossed the finish line in a phenomenal 34 minutes 34 seconds beating her 2011 time of 35 min 2 sec in the 10 kilometere race held under hot weather conditions in the South African capital, Pretoria.
Irvette van Blerk was close behind with a time of 35 min12 sec while Maxine Heine-Wacker finished third in 36 min 4 sec.
Meanwhile, in the men’s category, it was a fight to the end as the top three runners in the 21.1km distance all finished within the record time.
However, it was last year’s 10km champion, Stephen Mokoka, who grabbed the title with a record breaking time of 1 hr 4 min 35 sec, followed by Desmond Mokgobu in 1hr 4 min 42 sec and Lucky Mohale 17 seconds later.
Rene Kalmer, who has already qualified for the 2012 Olympic Games, set a new best mark as she won the women's 21.1km category. She came home in a time of 1 hr 13 min 9 sec shaving a full 1 min 16sec off the previous record to cap a sensational day of running in the Bestmed Tuks Race.
Louisa Leballo took in 1 hr 19 min 58 sec with the bronze going to Kim Laxton in 1 hr 22 min 50 sec.
