My guess on the differing distances for the woman vs. the men is that the range of competitiveness is fairly wide for the woman. Sure in the US we know they can cover the distance but does it lend itself to a truly competitive event?
For instance, the men do a mountain road stage of 125 miles; maybe a lead group of 8-10 riders with a sprint finish and the last placed rider showing-up 45 minutes later. For woman a 125 mile mountain stage would most likely be a single rider death-march with riders spread-out over the road for the next few hours. Yes possible, but from a competitive standpoint not too interesting. Heck, until a few years ago even a womans criterium would be a bunch of riders circling a course with a few coming-off every lap until a lead group remained and a sprint contested by the remaining 5-10 riders. Interesting to those invested in such an event, but for most with a stomach for a competitive event a field of 50 post-pubescent, wild-assed Juniors circling with five attacks a lap with a finish gutter-to-gutter would be more akin to racing than the female criterium miss-and-out.
So, with a womans Kilo instead of 500m, the time difference of first to 15th place would be sizable, same with 4000m pursuit with the 15th rider having no competitive chance before they even put on their shoes. Even on the world stage, you would be able to drive a truck through the time of 1st to 15th.
So relax everyone, there is some value to this and unless a lot has changed over the past 25 years, my guess is that when it comes to racing, a top-notched Intermediate rider barring outdated gear restrictions would still give the top female riders a good run for their money.

I'm pretty sure if the women's events were exactly the same as those of the men the results would show the women kicking the men's asses all over the track and the cycling world just isn't ready for that! Especially in the case of Sarah Hammer--she is one tough competitor! Just my two cents, of course!
