James claims second world title
Great Britain's Becky James has won her second gold medal of the Track Cycling World Championships with victory in the women's Keirin.
The 21-year-old from Abergavenny, sprint champion on day four, claimed her fourth medal from four events with a sensational triumph. She has a haul of two gold and two bronze medals from her third senior World Championships.
Britain finished the first World Championships on the road to the 2016 Olympic Games in Rio de Janeiro with five gold medals.
The women's team pursuit squad of Laura Trott, Dani King and Elinor Barker won gold, Jason Kenny won the men's Keirin and Simon Yates the men's points race to go with James' double.
The Welshwoman is the undoubted star of the five-day event, which she capped with a memorable win.
She was drawn behind the motorised Derny bike, with Germany's Kristina Vogel immediately on her wheel, and the Briton was forced to lead out as the pacing bike swung off the track with three laps to go.
Cuba's Lisandra Guerra Rodriguez made the first move with two laps to go but James held off the charge, and an attack from Gong Jinjie of China, to claim a stunning win, again celebrating with her grandparents, Kathleen and Ioan James.
Gong was second, with Guerra Rodriguez third.
Vogel, the sprint runner-up and considered the main challenger going into the final, crashed on the inside of the track, known as the Cote d'Azur, and failed to finish.
The World Championships are taking place without the now retired Victoria Pendleton, six times the world sprint champion, and Australia's Anna Meares, the Olympic champion, who is taking a sabbatical.
James, girlfriend of Wales rugby union wing George North, won two junior world titles in 2009 and is Britain's heir apparent to Pendleton, who won nine world titles across the sprint disciplines.
Three times Pendleton won three medals at World Championships, most recently in 2009, but never did she win four.
James, who is in the form of her life and won team sprint and 500m time-trial bronze medals in the opening two days, now has, emulating Meares, who won four in Melbourne last April.
James won Commonwealth Games silver behind Meares in 2010, but has only belatedly recovered her form after appendicitis and an Achilles injury which meant she was not in contention for London 2012. Rio 2016 is now firmly in her sights.
James said: "Oh my gosh. I can't believe it. Wow. It's going to take a good week for it to sink in, or two weeks, or a month.
"I just need someone to pinch me and tell me if it's really happening to me. I feel like it's a complete dream apart from the pain in my legs."
