The Swiss dominated at Sunday's Cape Argus Pick n Pay MTB Challenge at the Boschendal Wine Estate amidst scorching temperatures.

Martin Fanger and Esther Suss, both from Switzerland, were the first male and female to cross the 55km finish line. "I was surprised to win. It is my first time in this country and I didn't know the riders I was competing against today. South Africa is really cool and I think I'll be back for the MTB Challenge next year," Fanger said.

Erik Kleinhans (GT Bicycles) from Stellenbosch finished in second place with fellow Matie, Johnny Kritzinger (Schwinn), coming third. "It was hot out there, very hot. I aimed for a wine but I'm actually very happy with third place. Martin was very strong. I'm also impressed with Erik. He caught up to me in the last 1km."

David Bellairs, Co-Director of the Cape Town Cycle Tour Trust, described the race conditions as "very hot, dry and dusty, overall very testing".

Medi Clinic's Dr Basil Bonner, the official race doctor, said the medical tent had their hands full. "The weather was a major factor and we treated a number of cyclists for heat-related incidents. There were also a few falls, of which the majority were not serious."

Despite the extreme heat, a record number of 4 200 cyclists took part in the MTB Challenge, making it the country's biggest mountain biking event. "We attribute the ever increasing success of this event to the fact that it's a safe, family-friendly affair. After the race hundreds of families picnicked on the Boschendal Wine Estate's lawns, contributing to the wonderful atmosphere, commented Meurant Botha, Co-Organiser.

Last year's female winner, Heletje van Staden, flew back from the Sani2C on Saturday night to defend her title. Unfortunately the airline she flew with lost her bicycle, making it impossible for her to take part.

Esther Suss was the first female to cross the finish line.
