Radcliffe has not raced competitively since last October

The marathon world record holder, 33, wants to make her comeback on the road as part of her build-up to August's World Championships in Osaka, Japan.

"If things go well, I hope to be racing again in June - and a road race would be a better way to start," Radcliffe told The Daily Telegraph.

"I will race as soon as I'm ready but I don't want to commit to anything yet."

Radcliffe has now headed to her American base in Colorado where she will step up her training.

The 33-year-old started running again less than two weeks after Isla was born and is now just two kilograms over her normal weight.

"Recent tests I had done at Loughborough University showed I was close to normal fitness," said Radcliffe.

"I felt then as if I wasn't too far away from being ready to race. I am cautious - I don't want to get two months down the road and have problems.

"I will definitely be OK for Osaka."
