"Recently, my training has started to go very well," Radcliffe said in a statement on Wednesday. "I’m definitely ready to run a half-marathon, and the NYC Half-Marathon will give me important feedback about where I am.
"After the race in New York, I will consult with my coaching and medical teams and we will make the final determination as to whether I am ready to run the marathon in Berlin. It is certainly my hope to compete there."
Radcliffe, who has been struggling with injury problems, earlier this year had surgery on her right foot and has not competed since she won her third New York City Marathon in November.
The world championships in Berlin begin on August 15, with the women’s marathon going off on the final day – Aug. 23.
Two-time Olympic medalist Catherine Ndereba of Kenya will be one of the main challengers for the gold medal.
