Mandy the MIG, halfway through the anticlockwise Sellaronda in the Dolomites.
Fantastic emtb route, 37 miles, 1120m ascending, 5 ski lifts, 5 proper trails up to red, one crash {crashing not mandatory}. It circles the Marmolada glacier, you pass through many ski resorts, so only need to take minimal supplies with you, loads of place to eat en route. Took about 5hrs with a 30/40 minute lunch stop.
Navigated the whole thing with Komoot, which was amazing. Used one battery and one bar from another.
