Sven Kramer eased to another 5,000 metres victory as the second leg of the International Skating Union (ISU) Speed Skating World Cup season opened at the M-Wave Stadium in Nagano in Japan.
The Dutchman, a triple Olympic champion and long distance specialist, won the opening race over the longest distance in Harbin in China last weekend and was in fine form again in the 1998 Winter Olympic host city.
He clocked 6min 15.17sec, a new track record, to again ensure that his compatriot Jorrit Bergsma would have to settle for the silver medal.
Bergsma was timed at 6:15.70 as Kramer, who also claimed a surprise 1500m win in Harbin, again took top honours.
The podium was an all-Dutch affair as Douwe de Vries won bronze with a time of 6:17.65.
The Netherlands also came fourth on a day of dominance, with Erik Jan Kooiman stopping the watches at 6:18.58.
Elsewhere, the Czech Republic's Martina Sábliková also backed up her Harbin title by winning the women's 3,000m.
The three-times Olympic gold medallist was timed at 4:03.56, another track record on the Nagano ice.
Dutchwoman Antoinette de Jong, who finished in 4:04.53, had also broken the course best but could only watch as the Czech went quicker still.
Sábliková raced away from another Dutch skater Marije Joling, who eventually finished eighth.
Anna Yurakova claimed a surprising Russian bronze in 4:05.24.
Thanks to their back-to-back victories, Kramer and Sábliková have 200 points each at the top of the 5,000m and 3,000m standings respectively.
The World Cup leg will continue tomorrow with the 1000m, team pursuit and team sprint finals for both men and women.
