used endomondo and now trying Mytracks to keep track of rides, endomondo kept on giving silly altitudes, 600m+ in the cotswolds? My tracks is still wrong but less so, it tends to be about 50m higher than reality.
What i have noticed is that if i stop the tracking goes haywire rather than recording the same spot it shows me moving hundreds of meters in seconds.
So are there any other apps that may be more reliable? or is this just a fact of life and there is no better way.
