Silver service resumed by McGlynn

Archibald, meanwhile, put in a courageous ride for third spot in the women's 25km points race, finishing behind double Olympic champion Laura Trott, who won gold for England, and silver medallist Elinor Barker of Wales.

The 20-year-old from Milngavie made a massive surge in the final sprint of the race to claim the all-important five points she needed to gain a medal.

With her blue and white saltire-inspired hair tucked beneath a sleek aerodynamic helmet, she pedalled around the track like the proverbial swan, gliding serenely atop the surface while underneath the legs were going like pistons.

"It's an unbelievable pain," she said, describing the sheer physical effort required. "In my first Scottish National Points Race, I basically fell off my bike at the end.

"I had this kind of awakening moment where I remember this is what it feels like to empty yourself and it's only on very special occasions; that was one of them. It's an odd life and there's been quite a few bets and promises about getting on that podium.

"I'm really glad I didn't screw myself over and followed it through. I'm not disappointed to lose to Laura Trott and Elinor Barker, they are really classy riders."

Scotland have previously only won two medals in women's Commonwealth Games track cycling: Kate Cullen's bronze in the 25km points race in Melbourne eight years ago and the silver Charline Joiner and Jenny Davis took in team sprint in Delhi. That tally now stands at an impressive five.

For visually impaired rider McGlynn, 41, from Paisley, and her sighted pilot Haston, 33, from Edinburgh it marks their second silver of the Games.

"We always aimed for a gold medal but the English girls are top of their game," said McGlynn. "The competition here was the best in the world with the two Australian pairings and [Welsh rider] Rachel James who was pilot for Sophie at the world championships [when they won double gold]. It is top competition and for us to come away with a silver medal, we're delighted."

Haston added: "I wanted to win this one, but two silver Commonwealth Games medals is absolutely brilliant. Sophie and Helen were fantastic. That was a cracking ride. Well done to them."

Triple Paralympic champion McGlynn said that losing her UK Lottery funding at the end of last year provided a much-needed spur to prove her doubters wrong. "I still don't think I have peaked," she said. "I'm quite happy to be still second in the world. Yeah, I think I've proved something."

For Haston, meanwhile, it may mark her last competitive ride as a tandem pilot. "I always said I would finish after Glasgow because I don't get paid to cycle so I need to go back and work," she said. "Unless there is funding out there, it's back to work for me."

In the men's keirin, Scotland's Callum Skinner finished fourth in his heat and failed to progress to the second round. That left the nation's hopes pinned firmly on the stocky shoulders of John Paul and his compatriot Chris Pritchard, the latter rider having won his first heat in heroic style.

But it was not to be with Pritchard placing an agonising fourth after being beaten to the line by the cruel margin of 0.03sec to miss out on a place in the final. Paul, riding in the same heat, was sixth.

They finished ninth and 11th overall. Afterwards Pritchard climbed into the stands and proposed to his girlfriend Amanda Ball who, with 4500 eyes upon her, promptly said yes. McGlynn's long-term partner Graeme Hinchliffe also got down on one knee.

Australia's Matthew Glaetzer won the keirin with Sam Webster of New Zealand second and Mohd Azizulhasni Awang from Malaysia third.

The women's sprint finished in an Australian 1-2 with Stephanie Morton the victor and Anna Meares having to be content with silver as she missed out on claiming a record sixth Commonwealth Games gold.
