Marianne Vos of the Netherlands won the women's UCI World Championships road race for the second time, to add to her gold medal in this event from the London Olympics this summer.
There were perfect conditions for the women's UCI World Championships road race and all was well until the 19th minute, when a spectacular pile-up took out half the peloton.
A puncture was the most likely culprit.
It didn't affect the leaders, including Olympic gold medallist Marianne Vos who went on to win the race over 129 kilometres (80 miles).
Vos powered away from a leading group of five riders on the final climb up the Cauberg to cross the line in front of thousands of cheering fans - showing understandable patriotic pride.
The victory brought to an end a string of five world championship silver medals for Vos, who won her first world title in 2006.
Rachel Neylan of Australia was second, while Elisa Longo Borghini of Italy finished third - but it was Vos who deservedly crossed the line first in three hours, 14 minuites and 29 seconds to cap her glorious summer.
