... when my iPhone lost signal.

Is the data Strava collected since I'd begun this ride (I'd created then saved a route plan in it before I started out; signal lost about the 1/2 point) recoverable maybe?

Once I noted signal had returned, Strava showed me the Home Page with a Start button, so I began a new Record from that point.

Going back into Strava, I've done a new route that covers the route I rode this morning: 18.56 miles, 1,530' elevation.

Are there apps that can do a more reliable job of recording this kind of activity when cell signal strength is less than desired? I see several clubs use RideWithGPS for routing events, maybe that one's worth a try for some of the 'dead zones' around where I live and ride.
