The 2015 Indianapolis Women's Half Marathon is going to be September 19, 2015. I ran this half this year and had a great experience. I enjoyed participating in a women's only event (something I've been wanting to do for a long time) and appreciated all the amenities and perks of the race. It's a good size (was around 700 I think, I can't remember) and now that they moved the date to be in the fall, it should be great weather.
I likely will not be doing it in 2015 as there is a local marathon/half-marathon that I have my eye on that will be the weekend after Indy.
Hmmmmmm this is REALLY tempting. My aunt and I were talking about doing this race. I'd regret training for a half in August/September in the heat here in NC though. Decisions, decisions.
