Anyone a runner? (New Delhi)

Hi there.

I'm looking to move to Delhi from Washington DC in about 3 months, and am curious about the running scene out there. I am a bit of a serious runner, who likes long races. I am aware that there's usually a half marathon in Delhi around November, no? How do people in Delhi train for something like this? I'm told to be careful as a female, especially because there are safety issues?

Any insight on this would be wonderful.

Many thanks!
