THE last time Lizzie Armitstead raced in Glasgow she left with a Commonwealth Games gold medal around her neck.

While that triumph came on the road, the 26-year-old British rider showed her appetite for winning hadn't waned as round four of elite track cycling's Revolution Series came to the Sir Chris Hoy Velodrome.

In the opening session of the day, Armitstead, who rides for top Dutch women's team Boels-Dolmans, pulled off a series of aggressive attacks to win the women's 20km points race by a dominant margin.

The Olympic silver medallist took three laps on the main field and won four of seven sprints to finish on 89 points with Emily Kay (Team USN) second on 56 and 11-time Paralympic champion Dame Sarah Storey (Pearl Izumi Sports Tour International) on 44.

"I didn't really go in there with a plan to make it that hard for myself but I can't help myself when I'm in a race. I just become a different person," said Armitstead. "I love Glasgow. This is my first time on this track. It's nicer than Manchester - it's faster. It feels good. The venue is more intimate as well."

When Glasgow hosted the event last year, Armitstead was behind a microphone on presenting duties. "Yeah, I was doing some punditry," she said. "If I get the chance to ride, I prefer to ride, obviously. It's what I'm better at. I'm not very good at anything else."

For Armitstead, winner of the 2014 UCI Women's Road World Cup, it marked her second track outing of the year, having raced in round three of the Revolution Series in Manchester at the start of January. "Before that, I hadn't been on the track for a year," she said. "I never prepare for it. I just come in fresh and hope for the best.

"It's nice to come here and get confidence, see where I'm at, but it's difficult to see without the girls I'm racing on the road. My competitors are over 140km, so it's very different. It's good for an ego boost."

Scotland's Charline Joiner (Team WNT) finished fifth in the race and showed good early season form by pipping Armitstead on the line to take the opening sprint.

"I told myself: 'I need to win a sprint for the crowd in Glasgow, just to give everyone something to cheer about'," said Joiner. "They definitely had plenty to cheer about with Lizzie, though, seeing a world-class rider in action. She has so much power and is an unbelievable rider. I'm happy with how it went. I was fifth overall but would have liked a podium to be honest."

Armitstead, who will compete in the Tour of Qatar this week, looked strong again in the elimination race but had to settle for second as Kay stormed through to steal the win on the line. Scottish newcomer Neah Evans had an impressive ride and managed to hang on for third.

"It was good, I really enjoyed it," said Evans. "I'm naturally a sprinter so it's a lot longer than I'm used to racing but I'm definitely pleased with how it went."

The women's 10km scratch race proved another edge-of-the-seat thriller. Armitstead went off the front with 10 laps remaining where she was joined by Kay, Joiner, Emily Nelson (Team USN) and Manon Lloyd (Team USN).

It looked like the break would stick but a subsequent lull in the pace saw Ellie Coster (Team USN) and Storey catch the quintet. In the ensuing sprint for the line Nelson won out with team-mate Coster second and Armitstead third. Joiner was fifth.

The one-day event saw a record 30 Scots take part including Callum Skinner, who took a clean sweep of four golds at the 2014 British National Track Championships last September.

In the men's sprint, Skinner, riding for Great Britain, posted the second fastest time in qualifying with 10.046sec with only Olympic champion Jason Kenny faster in 9.972sec.

Skinner saw off Jiri Janacek of the Czech Republic in the quarter-final, while fellow Scot Jonathan Mitchell produced a blistering ride to beat Welshman Lewis Oliva (Team USN) and claim his place in the semi-finals.

Mitchell put in a brave effort against Kenny but couldn't do enough to progress. Skinner, meanwhile, dispensed with British team-mate Matt Crampton to tee up a thrilling final against Kenny.

After the cat-and-mouse formalities were concluded, Kenny proved the victor in two straight races. In the bronze medal race, Mitchell again rode well but lost 2-1 to Crampton.

Yet, both Scots could draw many positives from their efforts, not least Mitchell who remains a relative rookie in cycling terms having only taken up the sport in earnest a little over two years ago when the velodrome in Glasgow opened.

In the men's 30km points race US rider Bobby Lea (Majola Pushbikers) won with a final tally of 67. Irishman Martyn Irvine (Madison-Genesis) finished second on 50 points withYoeri Havic (Netherlands) third on 40.

Lea's winning streak continued in the 15km scratch race as he beat Adam Blythe (Orica-GreenEdge) into second with Rui Oliveira (Ignitr) third. Scot Phil Trodden (Rigmar Racers) was fourth.

The men's keirin final had three Scots in contention with Skinner, John Paul and youngster Jack Carlin. After a photo finish, Oliva finished in top spot with Carlin second and Paul third.
