I used 2 sets today: formula and slalom. And had 2 tracks. I cannot merge the tracks in gpsresults, so I manually uploaded and merged the tracks.
Al speeds are made with the 8.6, only the best alpha is made with the Formula + 11m2
Goal for today: 200+ km. And I did it.
It was not easy. Wind in the morning just enough for the 11.0m2. It was hard. Pumping, and pushing the legs all the time. Later on wind increased (after 60km with the formula) and I took the Slalom.
