Hi, I've been riding my bike in my usual known distance of 24km round trip (12km each).
However my Garmin instinct 2 solar tactical had shown total distance of 42km which is way off
Here's also discrepancy in data
- exaggerated altitude gain
- excessive avg speed, if you look at speed graph there is no way avg speed is close to max speed
Reasonable data
- avg grade adj speed is quite reasonable and if you calculate distance back by having avg grade adj speed x riding time = 18.4km/h x 1.3h = 23.92 km it's also reasonable for the ride.
Please take a look at my data and help me
