For one reason or another I do not have any nutritional information to accompany this wrapper.
More than likely, the wrapper is non-American, where nutritional info is not required.
Or, that portion of the wrapper could be missing or damaged.
I loved loved loved the Marathon bar! Spent years looking for a wrapper and even came close to acquiring an intact bar (with the 30-year-old bar still inside). I did finally track down a near-flawless wrapper, which I'm happy to share, if you'd like to see it!
The Marathon-like bar made by Cadbury and sold in the UK is the Curly Wurly. It's very close! In the States, you can get the Curly Wurly at Cost Plus/World Market or specialty candy stores--or purchase it online.
I, too, loved the Marathon Bar and wish M. & M./Mars would make it again! I remember this as a child back in the early seventies; a caramel braid enrobed in chocolate. I worked for Mars in the nineties and my boss told me that the bar was available in Europe under another name, which I can't remember.
I've seen Marathon Bars in Europe and Canada but they aren't the caramel and chocolate braid that we bought here in the U.S.; due to international trademarks, many candies you know and love will have different names or the bar inside isn't what you think it will be according to the label.
BY FAR THE BEST CANDY BAR I HAVE EVER EATEN. THESE WERE MADE IN THE 70'S I WOULD LOVE FOR THEM TO COME BACK INTO PRODUCTION. THEY WERE WONDRFUL!
