At that distance, you'll be pretty close to Glasgow or Edinburgh, depending on which route you've taken. There are some nice rolling hills for you to enjoy on the way. Nice rides on a motorbike.
Did you go through Langholm (the Muckle Toon) and up past Hawick, Selkirk and Galashiels on your way north? Or Lockerbie, Beattock and Moffat?
