Cape Town - The Absa Cape Epic got underway at Meerendal in blustery conditions on Sunday.
The 26km route, with around 700m of climbing proved a tough proposition for the riders, especially with strong winds throughout.
Karl Platt and Urs Huber (Bulls) were first over the line in a time of 1.04,37, a minute ahead of Nicola Rohrbach and Matthias Pfrommer (Centurion Vaude by Meerendal 2).
Samuele Porro and Damiano Ferraro (Trek-Selle San Marco A) finished in third.
The women's prologue was won by Robyn de Groot and Jennie Stenerhag (Ascendis Health) in a time of 1.17.35. They finished in 50th overall.
As is the norm, a number of sports people from other disciplines are taking part in the event.
Ex-Springbok Marius Hurter has teamed up with ex-Welsh international Colin Charvis. The pair ended in 636th position after completing the course in 2.12,32.
"Ja, it was quite windy and we were bobbing and weaving a bit," said Hurter.
Other participants in this years event include adventurer Riaan Manser and ex-Springbok captain John Smit.
