Jo Pavey has revealed her desire to have a second child but not before completing the transition from the track to the road at the London 2012 Olympics.

After making her third Olympic appearance in Beijing in 2008, finishing 12th in the 10,000m, Pavey took the next year off to start a family - giving birth to her first child Jacob in September 2009.

The 37-year-old had planned to make her first forays into marathon running that year while her hopes of doing so in 2010 were also put on hold as she opted to care for her newborn son.

However her long wait ended this April with Pavey making her London Marathon debut, finishing 19th with her time of 2:28:24hours inside both the 2011 World Championship and 2012 Olympic standards.

She had to pull out of a trip to Daegu with a foot injury this month but is expected to run an autumn marathon in order to prove her worth ahead of next year's Olympics.

At 37, and with Jacob to look after, Pavey's priorities have changed but, while readily admitting to wanting a second child, she insists her Olympic marathon ambitions are burning brighter than ever.

"At some stage I would love another child but running-wise the focus is 2012. It is a big opportunity and not many athletes have a home Olympics in their career," said Pavey.

"So I will definitely be running for a bit longer and if I had a second child it wouldn't be my retirement, if I am still running at a reasonable level then I will keep going.

"I need some more marathon experience, it is almost like a new sport for me, and I am picking things up now after the injury and hope to run again in the autumn.

"I feel really happy and Jacob is a bundle of energy and I am motivated by the challenge of moving up from the 5,000m and 10,000m on the track to running on the roads.

"I was pleased to achieve the qualifying time for the worlds and 2012 but there are a lot of talented girls in Great Britain and I will have to do other marathons in the lead up to the Olympics.

"Obviously not too close because of the recovery period but you are always aware that you need to show your fitness - you can't just do the qualifying time and drop off."

Despite not running a marathon in 2010, Pavey still managed to book herself runs in the 5000m and 10,000m at the European Championships - only to be forced to pull out through injury.

As well as finishing 12th in the 10,000m at the Beijing Olympics Pavey also finished fourth over the same distance at the World Championships in 2009 - and admits to having a score to settle on the track.

"It has been a natural progression for me into the marathon as I started doing the 1500m, 5000m and 10,000m and there is a bit of unfinished business in the 10,000m," she added.

"I was pleased with my position in Osaka even though I just missed out on a medal and in Beijing I had stomach problems and I would have liked to have improved my 10,000m on the track."
