Got a Garmin 520. The Garmin Connect app works well for setup of the interval workouts and subsequent downloading to the device. I reckon it is a good buy. Thxs Guys.

Is the touch screen not tricky to operate on a MTB, over rough terrain?.

I need to upgrade my Garmin device. I see that the 520, 810 & 1000 devices have an "Interval Training" feature. Do this work effectively for interval training? Does it give an sound when the interval starts and when it stop?
