Hi Mikael -
I’m afraid I have some bad news for you. It sounds like you were aiming for the imperial century achievement and jersey, is that correct?
Unfortunately, 100 miles is equal to 160.9 kilometers - you just didn’t push it quite far enough this time. If you had kept going, you would have seen a pop up announcement for the achievement and had the jersey awarded to your inventory at that time. The achievement pop ups are shown no matter what units are set in your display. You can also toggle from km to miles using the U key on the keyboard to have more accurate information about your distance during an attempt at these landmarks.
I hope this information helps you the next time you attempt the imperial century, Mikael. We’re all rooting here for you now, so good luck and ride on!
