Where has my route gone in the Activity app? I did a cycle ride at the weekend and recorded the workout on my Apple Watch. When I finished I saved the workout and could see the route in the Activity app on my iPhone.

Now a couple of days later I can view the workout stats such as distance and average speed. However, I can no longer see the route. I can see routes for other workouts.

Has anyone else experienced this and has a fix for it? I'm sure the data is still there
I recently had the same issue. I force restarted the watch and the next activity it showed a map again. 
Still testing if it resolved the issue for ever.
