The GB pair won the third sprint to go second briefly behind the Dutch. And even after Evans crashed, they stayed in touch in fourth overall.
After the race was briefly halted due to a crash suffered by a New Zealand rider, they managed briefly to get back on to the virtual podium, winning the eighth sprint out of 10.
But they were running on empty by that stage. When Denmark attacked them late on, they had no response, eventually finishing fourth overall behind Holland, Australia and the Danes.
“It’s so frustrating,” Evans conceded. “But our ultimate goal is the Olympics. We’ve learnt a lot here.”
Sprinters Jack Carlin and Joe Truman both failed to qualify for the sprint quarter-finals, Truman relegated for cutting the corner after thinking he had beaten Australian Nathan Hart.
It followed disappointing performances in the men’s and women’s team sprints and in the keirin.
“It hasn’t been our best week,” conceded sprint coach Justin Grace. “No excuses. We’ve got good riders and they’re in pretty good shape, but we haven’t executed very well this week.”
