Great photos, looks like a really beautiful ride! Sebastian is a cutie pie, I always really wanted to take my schnauzer along, I think she would have loved it, but she passed a few years ago so I just have to bring her in spirit.
My Strava thing seems to be fixed, turning off my location (gps) and then turning it back on again seemed to do the trick, I think it was sending weak gps signal, so it was cutting out. Ahhhhhh technology ;)
Sorry she passed. It's fun seeing dogs enjoy a ride.
