Olympic 5,000m and 10,000m finalist Jo Pavey will sit out the World Championships in August after announcing she is pregnant with her second child.

Pavey, who also claimed the silver medal at the European Championships in Helsinki in a memorable 2012, is due to give birth in September and will therefore miss the Worlds in Moscow.

Next year’s European Championships is the target for her comeback while the 2016 Olympic Games in Rio de Janeiro is a longer-term ambition.

“I fully intend to carry on and my aim is to make the team again in 2016 for the Olympic Games in Rio,” said 39-year-old Pavey.

“It will be very special if I can make those Games. I’ll be getting older, but I have been very encouraged to continue after running a PB in the 10,000 in London.

“Not many long-distance runners make four Olympics so going for a fifth has that extra added dimension, I still want to be competitive and would not be aiming to go just to take part. It would be a great opportunity.”

British Athletics head coach Peter Eriksson said: “We are delighted for Jo and (husband) Gavin and will work with her to ensure she can return to competition in 2014 in great shape.”
