Thanks for the link. I knew a new one would be coming out fairly soon. I worry, however, that, as women make up an ever-increasing %age of half-marathon runners, it will be used to justify an ever-increasing number of women-centric or women-only races, thus furthering the imbalance.
It's great that more people are running; it's just unfortunate that we have so many races which exist to discourage half the population from entering (or prohibit them altogether).
