MEDILLIN, Colombia (AP) -- Niek Kimmann of the Netherlands won the men's time trial and Caroline Buchanan of Australia took the women's race at the BMX World Championships on Saturday.
Kimmann covered the course in 36.858 seconds, edging Sam Willoughby of Australia by 0.037 seconds. Maris Strombergs of Latvia, the two-time Olympic gold medalist, finished third.
Buchanan finished in 41.641 seconds, 0.301 seconds better than Laura Smulders of the Netherlands. Mariana Pajon of Colombia, the 2012 Olympic gold medalist, was third at the course named in her honor.
The world championships conclude Sunday with the men's and women's elite races. A top-three finish for an American rider would guarantee an automatic berth on the U.S. Olympic team for the Summer Games in Rio in August.
