From the perspective of religious extremists, at least this is somewhat logical — if you’re trying to enslave women, you definitely don’t want them training to outrun you:
A week ago baton-wielding men threw petrol bombs and torched vehicles at a mini-marathon in Gujranwala, 135 miles south of Islamabad. The race – one of the first to allow female participation – ended with police firing tear gas and making more than 50 arrests. The threat of further violence forced the cancellation of other mini-marathons at the weekend in a direct challenge to President Pervez Musharraf’s policy of “enlightened moderation”. [The Guardian]
