Belgium took the gold and the rainbow bands after finishing 10 points ahead of GB, with 44 to Barker and Nelson's 34. Australia finished third despite suffering a crash during the 30km (120 laps) race.

"I was nervous because we'd only ridden one each before, we didn't know what to expect," Barker told BBC Sport on riding the madison.

"I'm not surprised at all by the Belgians wining," she added, "they are a madison nation, so hats off to them, they were impressive."

The silver medal is Barker's second of the 2017 championships, having taken second place in the scratch race on day one. Britain now has four medals with Chris Latham's bronze in the scratch race and Katie Archibald's stunning gold in the omnium.

Elsewhere, there was disappointment for young sprinter Ryan Owens in the men's sprint, as he lost out on a bronze medal, losing 2-0 to New Zealand's Ethan Mitchell. Owens claimed fourth place on his debut in the World Championships.

Chris Latham was also unable to make an impact on the men's omnium, with France's Benjamin Thomas narrowly winning his first world title ahead of former champion Aaron Gate of New Zealand in the final points race of the competition.

Earlier in the day, Katie Archibald missed out on a place in the finals of the individual pursuit by 0.258 seconds, which was eventually won by the talented young American rider Chloe Dygert, who took her second world title in these championships after victory with her country in the team pursuit.

"I don't feel fantastic, I woke up in agony. Maybe I would have slept better if I hadn't had so many messages," Archibald told BBC Sport

"I thought I could still give it a good go but I'm pretty disappointed and a bit embarrassed if I'm honest, I put in a lot of work.

"On paper it looks like I've not moved on in two years, so I don't feel so good about that. But it's amazing to have won the omnium world title."

Russia's Daria Shmeleva won the day's only other event in the women's 500m time trial, with Britain's Katy Marchant unable to make the cut for a final spot.

The championships continue tomorrow into the final day of events, with the men's madison providing the finale.
