I ran the forerunner 35 with endomondo connection today side by side with my phone running endomondo.
Comparing the 2 graphs in endomondo, the phone https://www.endomondo.com/users/340857/workouts/920605490 shows pace & altitude & the watch shows pace, cadence & heart rate https://www.endomondo.com/users/340857/workouts/920606267.
Does anyone know why the watch chart does not also show altitude?
