The 43-year-old Briton is due to receive a bronze medal from the 2007 International Association of Athletics Federations (IAAF) World Championships later this year after a retrospective drugs test on Turkey's Elvan Abeylegesse was positive.

She had originally finished second but has now been stripped of her silver medal, which was re-allocated to the United States Kara Goucher, who was promoted from third. 

A special ceremony is due to be held during this year's IAAF World Championships in August for Pavey to be awarded her medal. 

"People have joked about the fact I already know I'll be receiving a medal at the World Championships, even though it's one from 10 years ago," Pavey, preparing for the Virgin Money London Marathon on Sunday (April 23), said.

"But I want to be there competing.

"I'm honoured to finally receive it, it'll be really special.

"It's bittersweet having missed it 10 years ago. 

"It should have been a day of being proud but I was lying on the track at the end feeling frustrated, disappointed and that I'd let friends and family down."

Pavey added: "It will make up for it a great deal.

"I'm very grateful to everyone who has made it happen, to the people who caught the athlete who doped to those who arranged for me to have a ceremony."

The field for the London Marathon was supposed to be led by Kenya's Olympic champion Jemima Sumgong, who was due to defend the title she had won 12 months ago. 

She is no longer competing, however, following a positive test for erythropoietin.

Sumgong is now facing a four-year suspension.

"There are still cheats out there but it's nice things are going in the right direction," said Pavey.

"There's still work to do, the news Jemima Sumgong has been caught is devastating.

"When you see people running amazing races you want to think, 'Wow, I really admire that person'.

"It's a shame athletes like that are putting a question mark over performances."
