While following a planned course during a long multi-day race, my Garmin Edge 530 suddenly stopped following the course, forcing me to reload it.
It happened many times (5-10 times per day), and It had been the first time I observed this behaviour.
The courses where longer than usual (350 km), the settings where the same I had been using before without any problem (recalculation off etc.).
The only noticeable difference was that I had many Strava segments during the course, and my feeling Is that they somewhat "took control" over the main course when active, possibly causing the problem when an "off segment" was detected (as It sometimes happens).
Someone has experienced a similar problem?
Thanks
