Blummenfelt’s latest triumph comes a week after he came out on top in the season-opening World Triathlon Championships Series leg in Yokohama in Japan.

Boosted by that victory, the 27-year-old proved too strong for his rivals in Lisbon as he recorded an impressive time of 1hr 42mins 33secs.

Blummenfelt said he was delighted to secure victory after Norway finished fourth in yesterday’s World Triathlon Mixed Relay Olympic Qualification Event to miss out on a place at Tokyo 2020.

"We missed out on the relay podium and that was a big goal, so at least a good individual race followed," said Blummenfelt.

"I knew Gustav Iden was in the second pack and catching up so just tried to keep control on the bike and stay out of trouble because I know I’m in good run shape at the moment."

Max Studer, still flying high after helping Switzerland to Olympic Mixed Relay qualification less than 24 hours before, scooped silver after finishing in 1:42:41.

"It started well with a good swim to set it up, and then the large group made it a wait for the run," said Studer.

"To qualify yesterday and get a silver here after not much racing is great, the support from the training group has been amazing. I have showed the hard work has paid off."

The bronze medal went to Spaniard Genis Grau after crossing the finish line in 1:42.55 - one thousandth of a second ahead of Germany’s Jonas Schomburg.

"I never expected third here in such a quality field," added Grau.

"I just had to go full gas at the end against Schomburg and hold on through what was a super long sprint."

Action in Lisbon is due to conclude tomorrow with the women’s World Triathlon Cup event.

It will be the second race to take place within the recently-reopened Olympic qualification window which runs until June 21.
