Broken URLs

I'm using routing to make my links more search engine and user friendly but this is causing me an issue. If a user creates some information with a date in it ( e.g. "movies 5/4/14") then this will form part of the URL (e.g. "www.foo.com/movies+5/4/14"), when the link is clicked the Page.RouteData.Values("Name") is only "movies+5", the "4/14" is lost.

The page route I'm using is;

Routing.RouteTable.Routes.MapPageRoute("Route1", "{Name}/{*queryString}", "~/listIt.aspx")
What am I doing wrong?
