For a man brought up in the chilly climes of Bergen in Norway it was something of a surprise to hear Kristian Blummenfelt say he was a bit disappointed that the temperature had not been a bit higher at Monday's Olympic men's triathlon.

Blummenfelt overcame what everyone else seemed to consider debilitating sweltering conditions to forge clear in the last kilometer of the 10-km run course to take gold — Norway's first Olympic medal in the sport.

"Our team is world-leading for heat preparation so we were a bit disappointed it was not as warm as we were hoping for," he said, as the 6.30 a.m. start and a light breeze made conditions more manageable.
