Yes, there are a lot of differences in men's running and women's running. The fastest woman in the world is never going to be as fast as say the 20th man.
That's not entirely true. For shorter races, and up to the marathon, that is the case, but women do quite well when it comes to ultras. At the 50 and 100 mile races, women can (and do) beat out men on a fairly regular basis. (IIRC, women have a greater completion % at Leadville and the Comrades ultra, and probably other, less well-known, events.)
@roomthreeseventeen - I enjoy Crystal Palace, but I am a big Tigger fan. But, I also know that a lot of boys go through a phase where most of the current character meals aren't going to be "cool enough". I want a Peter Pan character meal - with Peter, Tink, Wendy, and Captain Hook. (I was hoping that they woud put a restaurant patterned after Hook's ship in the MK with the refurb, but that was just me.)
@Ash&Wes07 - If all you run are the Disney ones and Komen, it can skew your view of racing (or running in general). Komen (officially) did not allow men to run in the 5k until 2003 - some affiliates allowed it earlier, but as recently as 2002, the NYC and Peoria Komen races were still women-only. (It took a lot of people complaining, including male survivors, to force that change.) Disney races range from very egalitairian* to women-centric, and Komen races are women-centric (at the very least). While there are some jerks out there who don't want to be "chicked"**, I saw a lot less of that at Disney than at some other races.
* I suspect that part of it is because Disney races (IIRC) have no prize money, and are basically destination races. People run them mainly for the experience and the fun, not to set a PR or qualify for Boston.
** Some guys hate being passed by a girl, and do anything to fight it. I don't care who passes me. Until the last couple hundred yards. Try to pass me with 50 yards to go, and I am going to make you work for it. (It's a holdover from XC in HS - it was coached into us to kick as hard as you can at the end of every race. I still sprint it in at the end of a 5k or a 50k.)
