Lizzie Armitstead secured her third medal at her first World Track Cycling Championships as she battled to win bronze in the women's 25km points race.

Armitstead's bronze was Britain's ninth medal of the competition - two gold, four silver and three bronze.

"I'm the first British female to medal in a bunch race since 1988 and that was the year I was born," she said.

After the excitement of her sprint gold on Saturday, Victoria Pendleton failed to qualify for the keirin final.

The event was eventually won by China's Guo Shuang with France's Clara Sanchez taking the silver, and Willy Kanis of the Netherlands securing bronze.

The other British rider still competing on the final day was Jonny Bellis, who finished 13th in the men's omnium.

Bellis was 10th in the points race and 11th in the final event, the one kilometre time-trial as the event was won by Australian Leigh Howard.

France's Gregor Bauge succeeded the injured Sir Chris Hoy as world men's sprint champion after seeing off Malaysian challenger Azizulhasni Awang in the deciding round of three.

Britain's three entrants in the event - Olympic silver medallist Jason Kenny, Ross Edgar and Matt Crampton - were all eliminated in the quarter-finals.

Armitstead had already taken gold with the pursuit team and silver in the scratch race in Poland.

That made her the most successful member of the 19-strong British squad, alongside Pendleton, who also won time trial bronze and team sprint silver.

"I'm making a name for myself in this event and that's what I wanted to do," she said.

"Hopefully, I can secure my place in the future on the track, in the Olympics and so on.

"I'm happy but I can now admit to myself that I'm tired."

Italy's Giorgia Bronzini took gold in the points race, with silver going to Cuba's Yumari Gonzalez Valdivieso.

Her third place that event was the one that pleased Armitstead most.

"From lap one I felt awful," she said.

"The bronze is the most satisfying. It's strange, just because I've made it onto the podium.

"I'm really happy to get there, it's my favourite event and it's an Olympic event.

"I definitely exceeded my expectations halfway through that race - I didn't think I was going to come away with a medal there, so I'm really pleased."

The Otley-born rider will now revert to the road, spending the summer in Belgium with her Lotto-Belisol team.
