(CNN) -- French legend Julien Absalon took his status to new heights when he became the first rider to defend the men's mountain bike Olympic title.
Sabine Spitz of Germany celebrates her victory in the women's mountain bike on Saturday.
Absalon kept the gold in French hands for the third Olympics in a row -- following Miguel Martinez's victory at Sydney in 2000 -- thanks to a commanding display early in the 36km race which left his rivals trailing.
"The Olympic Games is a massive motivation for every athlete and four years passes quickly, as it has from Athens to Beijing," said Absalon, who finished well ahead of compatriot Jean-Christophe Peraud with Nino Schurter pipping world champion and Swiss compatriot Christoph Sauser to the bronze medal.
A highly-fancied Swiss trio failed to match Absalon's early pace after he had begun to steadily grind out a lead by the second of the eight scheduled laps.
"It's great to do the double. It feels totally different (from 2004), but this just confirms what I achieved in Athens," added Absalon, who denied that he had made his victory look easy.
"I had as tough a race as everyone else. When I saw the chance to make the break I went for it. After that I really gave it everything I had."
In the women's 27km mountain bike race, defending champion Gunn-Rita Dahle from Norway was one of several contenders to fall victim to a course that was finally mastered by Germany's Sabine Spitz.

She started fast and was soon racing on her own to gold ahead of Poland's Maja Wloszczowska, who finished with the silver ahead of Russian Irina Kalentieva.
"I feel pure joy at what I have finally achieved after so many years of hard work," said Spitz. "Winning the gold medal at the Olympic Games is the crowning glory."
