Pregnant Paula Radcliffe has revealed she is still running every day as she targets a return to competitive action at the 2007 World Championships.
Radcliffe has eased down her training but is running every day
Radcliffe competed in her last race before the January birth by taking part in the Nike Run London 10k on Sunday.
"It's quite hard at the minute because I'm having some very up-and-down days," said Radcliffe, 32.
"Some people run the whole way through. I don't think I will, but I'm not setting in stone when I'll stop."
Radcliffe went round the Hyde Park course in 43 minutes, some way below her best time of 30:1.09, in what she described as "a fast jog."
The three-time London Marathon winner is targeting a return to her true form in time for next year's World Athletics Championships in Japan.
However, Radcliffe is uncertain whether she will contest the 10,000m or the marathon, where she would defend her title.
"It depends how the training goes and how quickly I'm doing the mileage after having the baby," said Radcliffe.
"I'll just see how it is, what kind of birth it is and how I adapt.
"If things are going better in the 10k then I'll do the 10k. But how I'm progressing in training will determine what events I run before the worlds."
With Radcliffe taking it relatively easy in London, Jo Pavey won the women's title for the second time in three years with a time of 32:29.
The elite men's race was won by 5,000m specialist Chris Thompson in 30.04.
