Today I tested the navigation/ routes function of my Garmin 510 with a Spruit route in preparation for Berg and Bush as I had never used the function before. When I got to the end, the Garmin peeped, displayed end of "training ride" & then switched off by itself straight away. I now have no data from my ride as the ride wasn't saved which you usually do manually. I don't want this to happen after 99km of Berg and Bush Day 1 & I'm a bit bleak that I've lost a ride in terms of stats, goals, Strava, Vitality etc etc. I don't want it to happen again, please help. Thanks!
