Hmmm...

So... I changer the Nanos to ACE, and they are working better for me. Today in the woods, getting my new measurings. Got some distancies, but not all. And in the wekend is the 5 Nations in France. There is lots of down- and uphills, so again, lets see.. Maybe half way have to take bottle of Champagne, cause we are in the Champagne are ;).
