Olympic champion Pendleton beat Guo Shuang of China 2-0 in the best-ofthree final of the women's sprint on the same afternoon Sir Chris was ousted from the corresponding men's event in Copenhagen.

Sir Chris was bidding to reclaim the title he won in 2008 in Manchester prior to winning three gold medals at the Beijing Olympics.

But the 34-year-old Scot was beaten 2-1 by defending champion Gregory Bauge in the quarter-finals after being caught napping in his second round clash with Germany's Robert Forstemann.

Pendleton had a minor crash before coasting to a fourth successive women's sprint title and a fifth world champion's rainbow jersey in six years.

Lizzie Armitstead, meanwhile, claimed her second silver - and Britain's seventh medal in total - with second in the women's omnium.

Pendleton believes the accident may even have helped her deliver Britain's second gold.

"Having a little crash like that can sometimes give you quite a big adrenaline spike, so maybe it helped me in the end," said Pendleton.

Wins in Palma, Manchester, Pruszkow and Copenhagen have followed for Pendleton, who will ride for keirin gold tomorrow.

"I'm kind of expected to do so well these days that it feels like par for the job," she said.

"The whole world has such high expectations of us, it is difficult and only the best - as in gold - ever feels good enough."

Sir Chris  won the men's keirin at the Ballerup Super Arena on Thursday for Britain's first gold and had no excuses for his early exit.

"You've got to be the master of your own destiny and I made an error in the second round and I paid for that dearly," he said.

The gladiatorial sprint duels usually feature cat and mouse games in the first two of the three-lap contests, but Sir Chris was stunned by the tactics employed by Forstemann.

The German had apparent issues with his bike and officials requested it be adjusted, leaving Sir Chris to wait for almost four minutes.

When the whistle finally went, Forstemann was off, sprinting the entire three laps (750metres) and leaving Sir Chris to play catch up.

The Briton was slow starting on a big gear but responded, only to be beaten in a photo finish.

"I hold my hand up, it was my own mistake," he said.

"It's a three-lap race and there's nothing to say you can't attack from the start.

"It doesn't happen very often but it did and all credit to him for having that intuition to give it a go."

Sir Chris reached the last eight at the second opportunity, qualifying through the repechage, before coming up against Bauge (pictured).

In a titanic tussle with his successor as world champion, Sir Chris won the first contest before Bauge won two in a row to progress.

The manner of the defeat to Forstemann is unlikely to be repeated.

Hoy said: "If people are willing to take almost suicide moves to beat you, it's a backhanded compliment, because in a normal race they wouldn't have the speed to beat you.

"It's an important lesson I've learned, but it means now that it's in the back of my mind for every race - I won't lose like that again.

"But this is world standard racing, this is as good as it gets, so you can't expect to dominate every single race, every single time.

"As I've said numerous times I would sacrifice every medal between now and the London Games to be Olympic champion again."
