As a women the issue goes throughout the day. Try squatting in the bushes in riding gear if you think sitting on a toilet in riding gear is tough. Some women have gone with the "funnel" to stand up while urinating however to me it is gross to pack a plastic item that has been urinated through with me. Yuk, just Yuk. Probably the best solution is have morning coffee then start packing up, take care of business, gear up and ride without concern.
