Break-In: Highway vs. City Miles

Since the manual states 1200 miles with no details, does anyone know if city/start-stop miles are more significant and should be the majority of those miles? For example, I doubt I could take a 1200 mile road trip that is almost all highway and have an effective break-in. I'm assuming that the components need varied speeds and RPMs, but I'm not an engineer so I really don't know. Any thoughts...? (Hoping to have my car in a week)
